  • Characterizing Elements of Urban Planning in Magna Graecia Using
           Geophysical Techniques: the Case of Tirena (Southern Italy)
    • Authors: F. Cella; V. Paoletti, G. Florio, M. Fedi
      Pages: n/a - n/a
      Abstract: We present the results of a geophysical study at the site of Pian della Tirena, near the town of Nocera Terinese (Calabria, Italy). Geophysical imaging is a recent technique providing a reliable mapping of the three‐dimensional magnetization distribution below the ground and, thus, effectively estimating the depth of buried structures. The site studied gained archaeological interest following the hypothesis of the presence of two adjacent, but distinct, settlements. The first one of Hellenic/Hellenistic age (the Temesa of Brettian age), the second (called Tempsa) of Roman age. Even though the site was recently excavated, extensive investigation was not possible due to the broadness of the area and the scarceness of traces at the surface, making it difficult to plan a targeted survey. Two detailed geophysical (magnetic and electromagnetic) surveys were performed in 2006 and 2013 to provide the archaeologists with precise information about the type and position of the buried structures, and increase the efficiency of the investigation. The survey aimed to: (i) confirm and outline the existence of a true urban settlement instead of isolated dwellings; (ii) locate centres of manufacturing activities (local pottery and metal handicrafts); (iii) verify the existence of a boundary wall or road around the settlement. Our three‐dimensional analysis and interpretation detected several anomaly trends, most of which show a rather regular shape and orientation. This allowed us to infer the possible existence of a well‐developed urban network. The final results provided an archaeological interpretation, building upon the urban network and different use‐zones within the town. Copyright © 2015 John Wiley & Sons, Ltd.

  • Spatial Configurations of Water Management at an Early Angkorian Capital
           – Combining GPR and TerraSAR‐X Data to Complement an
           Archaeological Map
    • Authors: Till Frieder Sonnemann
      Pages: n/a - n/a
      Abstract: Hariharalaya was a medieval political centre of the eighth–ninth century ce, located on the northern shore of Lake Tonle Sap in Cambodia. Mapped in detail in the 1990s by means of aerial photographs and ground surveys, more recently ground‐penetrating radar (GPR) and high‐resolution satellite synthetic aperture radar (SAR) were applied to further interpret this complex archaeological landscape. In combination with remote sensing imagery, the two radiofrequency‐based imaging techniques were used to complement the existing archaeological maps. The area housed an extensive low‐density urban complex of earthen mounds and ponds, approximately 5 × 5 km square and centring on the Bakong, an early Angkorian state temple, crossed and encircled by a mostly disconnected water‐management network of embankments and canals. Extensive GPR surveys, conducted predominantly on the existing small roads and paths criss‐crossing the landscape, appraise the visible archaeological features with subsurface information. The analysis verifies the existence of channels and embankments, complementing the information with depth and width. The identification of additional, now desiccated, canals and river channels assisted in connecting a number of already mapped archaeological features, and helped to distinguish possible later additions, thereby untangling the water‐management network. Spotlight TerrSAR‐X satellite data together with satellite images of the visual spectrum complemented the analysis, by providing information about water saturation in areas inaccessible to ground surveys, marking out palaeochannels and providing clues about the landscape before development took place. This three‐dimensional interpretation informs on the functioning of this particular early Angkorian hydraulic system, adding to the understanding of water management in medieval Southeast Asia.

  • Green Waste and Archaeological Geophysics
    • Authors: James Gerrard; Liz Caldwell, Alisa Kennedy
      Pages: n/a - n/a
      Abstract: Environmental concerns, supported by regulatory frameworks, have encouraged the conversion of organic and biological waste into fertilizers and soil conditioners (so‐called green waste) that are being increasingly used on arable fields. Recent work has shown that the level of ferrous contaminants within this waste can have a detrimental impact on shallow geophysical prospection methods that use the principles of magnetism. This paper highlights the negative impact of this new agricultural practice on the historic environment and calls for tighter regulation of green waste. Copyright © 2015 John Wiley & Sons, Ltd.

  • The Impact of Spatial Sampling and Migration on the Interpretation of
           Complex Archaeological Ground‐penetrating Radar Data
    • Authors: Lieven Verdonck; Devi Taelman, Frank Vermeulen, Roald Docter
      Pages: n/a - n/a
      Abstract: In this paper, the impact of spatial sample density and three‐dimensional migration processing on the interpretation of archaeological ground‐penetrating radar (GPR) data is assessed. First, the question of how to determine the sample interval required to take full advantage of the spatial resolution capabilities of GPR without oversampling is addressed. To this end, we transform a test profile into the frequency–wavenumber (f–k) domain and estimate the required sample interval from the wavenumber values. For the presented data set, collected at the Roman town Ammaia (Portugal), this resulted in a transect spacing approximately three times the distance prescribed by the λmin/4 criterion (where λmin is the minimum observed wavelength). Second, the effect of three‐dimensional migration is assessed. The data set, sampled as prescribed by the analysis of the f–k plot, is migrated with two‐ and three‐dimensional phase‐shift algorithms, and the migrated results are compared with non‐migrated data. It is shown that certain subtle features are better resolved by three‐dimensional migration. Third, it is investigated whether three‐dimensional migration following the application of an interpolation algorithm such as Delaunay triangulation or interpolation based on τ‐p transform, can further relax spatial sampling requirements. For the GPR data shown in this article, it is demonstrated that interpolation and three‐dimensional migration of slightly aliased data, collected with a transect spacing equal to five times the outcome of the λmin/4 criterion, still allow a faithful reconstruction of the original, non‐aliased time‐slices.

  • Gradiometer and Ground‐penetrating Radar Survey of Two
           Reducción Settlements in the Zaña Valley, Peru
    • Authors: Parker Vanvalkenburgh; Chester P. Walker, Jennie O. Sturm
      Pages: n/a - n/a
      Abstract: In this study, we utilize ground‐penetrating radar and gradiometer survey to map buried architecture and investigate the political dimensions of the built environment at two Spanish colonial period archaeological sites in Peru's north coast region, Carrizales (C123) and Mocupe Viejo (74). Based on historical sources, we argue that both sites were founded during the Toledan reducción movement – a large‐scale attempt by Peru's viceregal government to forcibly resettle indigenous populations into planned towns in the 1570s ce. Coupled with excavations, geophysical survey has revealed diversity in how these planned towns were constructed. At Carrizales, domestic architectural features revealed through gradiometer survey and confirmed through excavations suggest that the town's layout broadly conformed to the prescriptions of reducción plans, centring on a large plaza and following a rectilinear layout. Ground‐penetrating radar results at the site were limited by high soil salinity. In contrast, at Mocupe Viejo, ground‐penetrating radar, gradiometer survey, and excavations have recovered no evidence of a gridded street plan, and demonstrate that the church was located in an idiosyncratic position. Together, these results suggest that the resettlement process was contested and that plans were modified to serve more proximate political, ecclesiastical, and practical concerns, illustrating the limited reach of colonial state power in the sixteenth century.

  • Geophysical Investigations on the Viking Period Platform Mound at Aska in
           Hagebyhöga Parish, Sweden
    • Authors: Martin Rundkvist; Andreas Viberg
      Pages: n/a - n/a
      Abstract: Aska hamlet in Hagebyhöga parish, Östergötland (Sweden), is famous among Viking scholars for a rich female burial under a low cairn that was excavated in 1920. The main visible archaeological feature of the site is an enormous barrow, but its contents have not been excavated. As the barrow is oval and has an extensive flat top, it has been hypothesized previously that rather than a grave superstructure, this might be an uncommonly large raised foundation for a long house. We occasionally see this type of feature at elite manorial sites from the period ad 400–1100. We have tested this idea at Aska with ground‐penetrating radar, securing the clear and detailed floor plan of a post‐supported hall building almost 50 m long. Its closest known architectural parallel, also sitting on a similar platform, has been excavated at Old Uppsala, the late first millennium ad political and ceremonial centre of the ancient Swedes. At Aska, it appears that we have found another such real‐world correlate of the Beowulf poem's royal mead‐hall Heorot, but in this case located in a smaller and less powerful polity. This all suggests a petty royal status for the owners of the Aska hall, who enjoyed connections with Scandinavia's top political elite. Copyright © 2014 John Wiley & Sons, Ltd.

  • CORONA Photographs in Monsoonal Semi‐arid Environments: Addressing
           Archaeological Surveys and Historic Landscape Dynamics over North Gujarat,
           India
    • Authors: Francesc C. Conesa; Marco Madella, Nikolaos Galiatsatos, Andrea L. Balbo, S. V. Rajesh, P. Ajithprasad
      Pages: n/a - n/a
      Abstract: Here we illustrate a ground map approach that uses orthorectified CORONA KH4B images and declassified topographical maps to study historical land‐use dynamics and to help planning archaeological survey in the monsoonal semi‐arid alluvial plains of North Gujarat, India. In spite of its generalized use in archaeological applications, CORONA photographs have rarely been used in Indian archaeological contexts. The methods discuss a cost‐effective and integrated protocol for: (i) obtaining ground control points (GCPs) and orthorectify CORONA photographs when very high‐resolution imagery or detailed topographic maps are not available; and (ii) evaluating the integration of declassified datasets into Google Earth Pro for addressing archaeological surveys in remote areas. The merging of CORONA imagery with declassified USA and the former USSR historical military maps provided a picture of the human–environment interaction in North Gujarat of the past 40 years, prior to the intense development of mechanical agriculture and regional irrigation channels. We conclude by identifying the human and climate‐induced taphonomical processes that are obliterating a fragile landscape characterized by archaeological scatters located in fossilized sand dunes.

  • A Template‐matching Approach Combining Morphometric Variables for
           Automated Mapping of Charcoal Kiln Sites
    • Authors: Anna Schneider; Melanie Takla, Alexander Nicolay, Alexandra Raab, Thomas Raab
      Pages: n/a - n/a
      Abstract: Analysing the spatial distribution of anthropogenic relief structures can contribute to the understanding of past land‐use systems. With automated mapping routines, small relief forms can be detected efficiently from high‐resolution digital terrain models (DTMs). In this study, we describe an approach for the automated mapping of charcoal kiln sites from an airborne laser‐scanning DTM. The study site is located north of Cottbus, Germany, where an exceptionally large historic charcoal production field has been documented in previous archaeological surveys. The goal of this study was to implement, evaluate and improve an automated GIS‐based routine for mapping these features based on the template‐matching principle. In addition to the DTM, different morphometric variables were evaluated for their suitability to detect kiln sites. The mapping results were validated against a comprehensive database of kiln sites recorded from archaeological excavations and via manual digitization. The effects of irregular kiln‐site geometry and DTM noise were evaluated using synthetic DTMs. The results of the synthetic DTM mapping show that the template‐matching results differed depending on the morphometric variable used for the mapping process. In accordance with this observation, a validation of the mapping procedure for the field site suggests that feature mapping can be improved. In particular, the number of false detections can be reduced using a combination of morphometric variables. For the validation area, the kiln sites with diameters of at least 10 m were mapped using the automated routine, with detection rates that were close to those of manual digitization. Therefore, the described method can considerably facilitate the mapping and distribution analysis of kiln sites or similar small relief forms that are prominent in a specific landscape.

  • Structure of an Ancient Egyptian Tomb Inferred from
           Ground‐Penetrating Radar Imaging of Deflected Overburden Horizons
    • Authors: Adam D. Booth; Kasia Szpakowska, Elena Pischikova, Kenneth Griffin
      Pages: n/a - n/a
      Abstract: Geophysical data acquisitions in most archaeological campaigns aim to image the target structure directly. The presence of a target, however, may be inferred from its interaction with surrounding layers, if its relationship with those layers can be characterized sufficiently. In this paper, we show the use of ground‐penetrating radar (GPR) to detect the subsurface continuation of the Ancient Egyptian tomb of the high‐official Karakhamun (Theban Tomb 223) at the South Asasif tomb complex (Luxor, Egypt). Data were acquired using a Sensors & Software pulseEKKO PRO system, equipped with antennas of 500 MHz centre‐frequency, on a silty–sandy sediment surface directly over the target structure. A test vertical radar profile (VRP) suggested that the tomb superstructure was buried too deeply beneath sedimentary overburden to be imaged directly: 500 MHz energy would propagate for only ~2 m before becoming undetectable. Attenuative layers within that overburden were strongly reflective, however, and could be used to provide indirect evidence of any underlying structure. When observed in the GPR grid, these layers showed a discrete zone of deflection, ~0.9 m in amplitude and ~4 m wide, aligned with the long‐axis of the tomb. This deflection was attributed either to a collapsed vestibule beneath the survey site, or sediment settling within an unroofed staircase descending from ground‐ to tomb‐floor‐level; supporting evidence of this was obtained towards the end of the excavation campaign and in the following year. We highlight the value of such indirect imaging methods as a potential means of improving the capabilities of a given geophysical survey system, in this case allowing the GPR to characterize a target at greater depth than would typically be considered practical.

  • A Comprehensive Magnetic Survey of a Neolithic Causewayed Enclosure in
           West‐central France for the Interpretation of Archaeological
           Features
    • Authors: Vincent Ard; Vivien Mathé, François Lévêque, Adrien Camus
      Pages: n/a - n/a
      Abstract: This paper describes an interdisciplinary study of the Neolithic causewayed enclosure of Bellevue (Chenommet, France). Geophysical investigations and archaeological excavations were used alternately in order to optimize the acquisition of accurate data at different spatial scales: mapping of major structures was obtained by magnetic prospection of the whole site, while excavation identified small features weakly expressed in the prospecting results. Measurements of magnetic susceptibility and total magnetic field anomalies were also recorded during the excavation in order to identify the source of the magnetic signal of the ditches. This mutual transdisciplinary contribution is also methodological: the geophysics reveals archaeological information invisible to the eye of the archaeologist and, in turn, the excavation allows refinement of the interpretation of the geophysical data by identifying the sources of signal variations. This article presents the results of the first comprehensive magnetic mapping of a Neolithic causewayed enclosure in the west of France. Copyright © 2014 John Wiley & Sons, Ltd.

  • A Multidisciplinary Approach to Reveal and Interpret ‘Missing’
           Archaeological Features at the Masseria Pantano Site in Apulia (Southern
           Italy)
    • Authors: Massimo Caldara; Marcello Ciminale, Vincenzo De Santis, Mariangela Noviello
      Pages: n/a - n/a
      Abstract: A non‐invasive investigation, integrating aerial photography and high‐resolution magnetic survey, was carried out at the Masseria Pantano site (Apulia, Southern Italy) to obtain a more detailed reconstruction of an extensive ancient settlement, which revealed different phases of human frequentation. The results of the ground‐based survey were also used to guide some archaeological excavations, which brought to light, mainly, parts of Medieval wall and column foundations. The correlation between the magnetic anomalies and archaeological remains was very satisfying, except for the lack of a source body that could explain the origin of a positive anomaly, the intensity and extent of which is very significant. A supplementary magnetic survey combined with stratigraphic interpretation from two boreholes, followed by susceptibility measurements, were able to solve this interesting partial misunderstanding between archaeological and magnetic data. This approach revealed clear evidence for a canal, probably Roman in date, which lies beneath the presumed ancient surface identified during the excavation. Copyright © 2014 John Wiley & Sons, Ltd.

      Abstract: The city of Iznik, called Nikaia or Nicaea in ancient times, is located in northwest Anatolia, Turkey. Nicaea is renowned especially for the first Council of Nicaea convened by the Roman emperor Constantine in ad 325 in an attempt to unify the Church. During an international field course on the geophysical exploration of archaeological targets we detected the remains of a small previously unknown Byzantine church on a fallow lot of land inside the city. The church is oriented parallel to the ancient Hippodamian street grid that deviates from the modern street system of the quarter by ~45°. We found the contours of the nave, two aisles and three apses as well as evidence of a partly refilled grave. The geophysical measurements indicate that the foundations of the church consist of low‐porosity hard rock with a low magnetic susceptibility, probably limestone or sandstone embedded in fluvial sediments. The field study is based on ground‐penetrating radar (GPR), magnetics, electric resistivity tomography (ERT) and microgravimetry. It highlights the strength and necessity of combining different geophysical methods in exploring and characterizing archaeological sites. In fact, the foundation walls of the church do not show any magnetic anomaly but could be delineated clearly only by GPR. The wall remains appear as highly resistive spots in ERT. By converting the three‐dimensional GPR image into an electric resistivity model we could verify that the ERT results fully correspond to the ruins found by GPR. The structure interpreted as a loosely refilled grave is indicated mainly by a weak gravity anomaly (~9 μGal) and a diffuse reflection pattern in GPR. Electric forward modelling shows that this structure leads to an additional increase of a high resistivity anomaly, which is primarily caused by foundation rocks, but it cannot be resolved within the ERT pattern a priori.

  • Use of Integrated Geophysical Methods to Investigate a Coastal
           Archaeological Site: the Sant'Imbenia Roman Villa (Northern Sardinia,
           Italy)

      Abstract: We report here a multimethod geophysical investigation of the Sant'Imbenia Roman villa archaeological site in northern Sardinia (Italy). The main objective of this study is optimizing a non‐invasive approach to reconstruct rapidly the geometry of coastal sites. A hitherto unexplored area of approximately 700 m2, adjacent to excavations, was investigated using ground‐penetrating radar (GPR) and electrical resistivity tomography (ERT) surveys. The Sant'Imbenia villa is close to the present‐day shoreline and subject to very high erosion rates and burial. A comparison of the high‐resolution GPR and ERT models was made, and their integrated results are discussed in terms of providing a more complete picture that would not be attainable using a single method. Geophysical analysis combined with archeological prospecting has revealed buried buildings north of the excavated part of the archaeological site. The results show that in this coastal environment ERT survey provided the most accurate reconstruction at the deeper wet levels of investigation. Copyright © 2014 John Wiley & Sons, Ltd.

  • Edge Detection of Archaeomagnetic Data: a Study from the City of Pisidia
           Antiocheia, Turkey
    • Authors: Muzaffer Özgü Ar𝚤soy

      Abstract: Magnetic survey is one of a number of methods used in archaeological geophysics for detecting and mapping archaeological artefacts and features. Recent magnetic instruments have become both faster and more sensitive as a result of technological and industrial developments. Hence, magnetic methods are becoming an accepted part of archaeological projects. Mapping the edges of magnetic sources is a problem of fundamental importance in magnetic interpretation. Commonly used edge‐detection filters are considerably affected by the presence of noise because this requires the computation of horizontal and vertical derivatives of the magnetic data. Archaeomagnetic data are often dominated by large‐amplitude anomalies that mostly originate from the presence of noise and other environmental effects. Prior to application of the edge‐detection filters, an upward continuation of the archaeomagnetic anomaly or low‐pass filtering may be used to reduce environmental effects. Another useful approach is to apply edge‐detection filters to the pseudogravity‐transformed data. This paper compares the results of common edge‐detection filters applied to the original and pseudogravity‐transformed archaeomagnetic data. In the concept of edge detection, the feasibility and capability of the pseudogravity transformation is demonstrated using a real archaeomagnetic dataset from the ancient city of Pisidia Antiocheia in the province of Isparta (central part of Turkey).

  • Assessing the Condition of the Rock Mass over the Tunnel of Eupalinus in
           Samos (Greece) using both Conventional Geophysical Methods and Surface to
           Tunnel Electrical Resistivity Tomography
    • Authors: Gregory N. Tsokas; Panagiotis I. Tsourlos, Jung‐Ho Kim, Constantinos B. Papazachos, George Vargemezis, Petros Bogiatzis
      Pages: n/a - n/a
      Abstract: The surviving Tunnel of Eupalinus comprises one of the greatest engineering achievements of ancient Greeks. The tunnel itself (1036 m long) was carved in the sixth century bc through solid rock by digging from both ends and advancing to the central meeting position. The method for achieving the meeting of the two simultaneously advancing branches is still unclear. The ancient lining shows damage, indicating instability of the rock mass, presumably due to tectonic action. At certain points, the damage becomes more severe and partial collapses are observed. Therefore, the monument is threatened and measures have to be undertaken to restore its stability and secure the safety of future visitors. The geophysical investigations reported here comprise part of a geotechnical study. The aim of the geophysical survey was to image the subsurface from the ground surface to the ceiling of the tunnel and, if possible, thereby provide information on the quality of the rock mass. A variety of well‐established methods (VLF, self‐potential, seismic refraction and electrical resistivity tomography) were used for this purpose, and also the relatively novel measuring approach of laying out electrodes in a ‘tunnel to surface’ mode. The latter method was an attempt for achieving tomographic imaging of the rock mass over the tunnel. Finally, the results of all the methods applied were combined and integrated in order to assess the tectonic regime above the Eupalinean Tunnel. Fractures and shear zones were detected and imaged. Further, the elastic moduli were determined at specific spots. In general, the geophysical interpretation matches well with the visible manifestations of the instabilities of the rock and provides clues for explaining their origin. The ‘surface to tunnel’ imaging provided increased resolution, which was a great advantage. Additionally, it is concluded that the construction of the tunnel was chiefly a product of survey method rather than consideration of geological factors. Copyright © 2014 John Wiley & Sons, Ltd.

  • Lidar Investigation of Knockdhu Promontory and its Environs, County
           Antrim, Northern Ireland
    • Authors: Rory W. A. McNeary
      Pages: n/a - n/a
      Abstract: A high-resolution aerial lidar survey (up to 40 points m-2) has been carried out in the environs of Knockdhu Promontory in the Antrim Uplands, which is recognized as one of Northern Ireland's most important relict multiperiod archaeological landscapes. This lidar survey was amongst the first such surveys commissioned specifically for archaeological purposes in Northern Ireland and has helped to re-evaluate the archaeological landscape character of a 9 km2 study area and inform future conservation studies. Sampled ground observation was undertaken in an attempt to provide a higher degree of interpretive integrity. These field observation exercises also highlighted the importance of the high vertical resolution of the data (0.05 m at 2σ (95% confidence level)) in delineating extremely subtle upstanding earthwork features that had hitherto gone unnoticed. Much of the archaeological evidence identified can be broadly ascribed to the early post-medieval period (ad 1599–1750); this includes field boundaries, cultivation furrows, enclosures, transhumance huts, abandoned settlements and associated pathways, but the higher ground of the Antrim Plateau in this locality is also characterized by evidence of prehistoric activities and substantial earthworks survive such as the ‘Linford Barrows’ and ‘Knockdhu Promontory Fort’. The lidar study has identified as many as 285 previously unrecorded potential archaeological sites and amended existing records within the Northern Ireland Sites and Monuments Record (NISMR) and has proved transformational as a technique to ‘open up’ the Ulster uplands for archaeological study.

  • A Multidisciplinary Approach to Medieval and Early Modern Land Use: a Case
           Study from Southeastern Austria
    • Authors: K. Patrick Fazioli
      Pages: n/a - n/a
      Abstract: This paper presents an integrated multimethod approach to the prospection and reconstruction of medieval and early modern rural landscapes in southeastern Austria (ca. 1100–1700 ce). Pedestrian surface collection, soil phosphorus analysis, and targeted test excavation, along with place‐name and field‐shape data, were used to investigate patterns of settlement, land use and landscape organization. The results from fieldwork revealed an inverse relationship between surface ceramic densities and soil phosphate levels, suggesting different areas of rubbish disposal, habitation and agricultural practices. This case study illustrates both the benefits and challenges of synthesizing archaeological, geochemical and historical lines of evidence in the exploration of past human landscapes in central Europe.

  • Magnetic Susceptibility Detection of Small Protohistoric Sites in the
           Raganello Basin, Calabria (Italy)
    • Authors: P. M. Van leusen; A. Kattenberg, K. Armstrong
      First page: 245
      Abstract: This paper presents pilot geophysical investigations carried out in 2005–2006 by the Groningen Institute of Archaeology in northern Calabria, Italy. The aim of this work was to find out if and how surface magnetic susceptibility (MS) measurements might be of use to correct significant visibility biases in the results of earlier large‐scale systematic and intensive field‐walking, in particular for unobtrusive rural protohistoric sites. It was found that MS yields encouraging results under specific geopedological conditions, but that a better understanding of post‐depositional site histories and large‐scale geomorphology‐driven MS variations is needed before an effective MS‐based detection protocol in support of large‐scale field‐walking can be developed; follow‐on studies are now being conducted by the authors to this end.

  • Geophysical Survey in Sub‐Saharan Africa: magnetic and
           Electromagnetic Investigation of the UNESCO World Heritage Site of Songo
           Mnara, Tanzania
    • Authors: K. Welham; J. Fleisher, P. Cheetham, H. Manley, C. Steele, S. Wynne-Jones

      Abstract: Magnetometry and Slingram electromagnetic surveys were conducted at the UNESCO World Heritage Site of Songo Mnara, Tanzania, as part of a multinational programme of investigation to examine the uses of space within and outside of this stonetown. The town was a major Islamic trading port during the fourteenth and fifteenth centuries. The surveys detected significant evidence for the containment of activities within the town walls, and previously unknown anthropogenic activity was revealed between the existing coral rag buildings, as well as within the open areas inside the town. Over 40 areas of magnetic disturbance were identified that corresponded directly with areas of high magnetic susceptibility in the Slingram electromagnetic in‐phase responses. On excavation many of these anomalies were found to correlate with wattle and daub structures, indicating a hitherto unidentified population, and the location of the anomalies also suggests a potentially deliberate delineation of space within the open areas of the stonetown. The combined results of the three geophysical data sets indicate that there are clear delineations in the use of space within Songo Mnara. This, coupled with the presence of industrial activities and evidence of more ephemeral occupation, neither of which had previously been recorded at the site, indicates that the pre‐existing town plan is in need of significant reappraisal. The current plan, based upon the remains of extant and collapsed coral buildings, can now be updated to incorporate the more ephemeral aspects of Swahili sites, including activity areas, and notably, the homes of the ‘hidden majority’ of the population. The results establish the benefit of a combined approach at these sites, and demonstrate that further invasive and non‐invasive exploration is required in order to fully exploit the significance of the role of geophysical techniques in understanding Swahili towns. © 2014 The
