3D model of the Can Sadurní cave

Graphic and metric information about the site and its environment and about the different structures and artefacts located are indispensable for the optimal management of an archaeological excavation. A Geographic Information System (GIS) proves useful in managing and analysing information and data obtained from different sources. Two techniques of data capture, Terrestrial Laser Scanning (TLS) and close range photogrammetry, are used to generate accurate and high-resolution 3D models of a cave, the silos and a combustion structure at the Can Sadurní site (Begues, NE Spain). This site is especially noteworthy on account of its complete stratigraphy of the Catalonian Holocene. The capture and processing of the photogrammetric and TLS data used to generate 3D models are discussed in detail. These models cannot be obtained by classic archaeological techniques since the record is made layer by layer, approximately one decimetre apart, with the result that the information between the layers is lost. Our findings highlight the potential of these techniques for obtaining accurate and photorealistic models that facilitate a complete analysis of the available information at an archaeological site.     

Exploring the season of mound building through oxygen isotope geochemistry at the Garden Patch site,Gulf Coast Florida,USA

ABSTRACT

The American Southeast saw the development of large ceremonial village centers, the coalescence of households, and monumental architecture integrated into village layout during the Middle Woodland period (ca. AD 1–600). These shifts toward more sedentary lifeways occurred independently of, and prior to, the domestication of plants across the Southeast. This paper examines the seasonality of monumental construction at the Garden Patch site located on the central Gulf Coast of Florida. This site contains evidence for rapid mound construction that followed a predetermined site plan. Here, we present oxygen isotope analyses of archaeological mollusk shells (Crassostrea virginica) to evaluate the seasonality and periodicity of monument construction. We conclude that mound construction occurred during the cooler months of the year. Ultimately, this contributes to an anthropological understanding of the development of these early ceremonial centers in the Southeast.     

The Dynamics of Heritage-Making at an Archaeological Site in South 24 Parganas,Bengal, India

Archaeological heritage is seldom fixed in time. Heritage-making is an ongoing process deeply entwined with social/cultural memory and identity formation. These processes are traced through an archaeological monument, located in the Sundarbans, in the South 24 Parganas district of West Bengal, India. The monument, named ‘Jatar Deul’, is a brick tower, stylistically labelled as a rekha deul — a curvilinear tower with a cruciform ground plan —belonging to the Orissan architectural style. Its exact chronology is unknown, as is its creator, although it is stylistically dated to the thirteenth century ce. It has survived more in myths, legends, and local tradition than in historical sources. This paper explores how the monument becomes a site of memories and how multi-vocal identities are forged around the locus of the site, now revered as a sacred place of Shaiva worship. The Postcolonial State has only a marginalized presence and the main stakeholders remain non-professional archaeologists, local schoolteachers, and the local population living in close vicinity. Identity work at the site is no longer the archetypal Bengali/regional identity seen in the pre-independence context, but reflects sub-regional cultural/religious affiliations. This paper is the result of ethnographic research, particularly interviews, of select sections of the local community, focusing on the recent organization of an annual fair at the site, which has thrown up questions on archaeological tourism. On the whole, this study examines how an archaeological monument is shaped and formed in the present in contemporary South Asia.     

Terrestrial laser scanning and close range photogrammetry for 3D archaeological documentation: the Upper Palaeolithic Cave of Parpalló as a case study

Graphic and metric archaeological documentation is an activity that requires the capture of information from different sources, accurate processing and comprehensive analysis. If monitoring of the state of conservation is required, this task has to be performed before intervention, during and after the completion of the works in a repetitive way.This paper presents the use of terrestrial laser scanning (TLS) in order to effectively produce, prior to intervention, accurate and high-resolution 3D models of a cave with engravings dating back to the Upper Palaeolithic era. The processing of the TLS data is discussed in detail in order to create digital surface models. The complexity of the cave required the integration of two techniques, TLS and close range photogrammetry to yield not only traditional drawings such as sections and elevations, but also photo-realistic perspective views and visual navigation worlds fully operational in 3D environments. This paper demonstrates the potential of integrating TLS and close range photogrammetry to provide both accurate digital surface models and photo-realistic outputs. This processed data can be used to systematically improve archaeological understanding of complex caves and relief panels of prehistoric art with tiny engravings.     

Combining New Awareness and Public Support for Archaeology with In Situ Preservation of an Archaeological Monument

Preserving archaeological remains in situ is one of the main objectives of the Valletta Treaty, which was signed by the Dutch government in 1992. Subsequently, preservation in situ has become one of the pillars of archaeological heritage management in the Netherlands. Another objective of the Treaty is the promotion of heritage education and raising of public awareness for the protection and investigation of archaeological heritage. Until recently, this goal has received too little attention. The design and building of an underground visitor centre, DOMunder, raised an important question: How can we transform an archaeological monument into an asset for the community and at the same time ensure long-lasting preservation? Not many parallels exist, as most archaeological sites in urban environments are seen as a burden for development. Sites are generally either excavated or left in situ; in both cases the archaeology remains invisible and inaccessible to the public. In the case of DOMunder, the location in a wet sedimentary environment provided even more challenges. This paper focuses on a few of the many questions and problems that were raised before and during the building process and the (preliminary) answers and solutions.     

Saving the Sweet Track: The in situ preservation of a Neolithic wooden trackway,Somerset, UK

Abstract

The Sweet Track is the oldest known wooden trackway in Europe. Part of the trackway is preserved in situ in a nature reserve under an active system of hydrological management, designed to prevent damage to the monument from desiccation. The English Heritage-funded project, reported here, was established to assess the condition of the monument and the effectiveness of the management regime. The results have shown that although the trackway is highly deteriorated it still holds a wealth of archaeological information. The decay of the wood probably occurred gradually over several thousand years but the present management regime should be able to ensure its continued survival.     

Archaeology,conservation and the late twentieth-century village landscape: With particular reference to Westmorland and North Lancashire in northwest England

Abstract

This paper argues that the present landscape and village is of archaeological significance and is needed both to understand and to preserve a representative sample of the past. It explores the relationship between archaeological data and monument types, and landscape character. Landscape assessment, including attribute analysis, is advocated as an essential archaeological method separate from the process of value judgement and selectivity. It concludes that function and process are as important as period in determining conservation strategies, and the potential role of sustainable development is discussed. The importance of village plan forms, vernacular architecture, field and landholding patterns is stressed, together with the need to recognize the historical importance of industrial villages.     

Ringforts or Fairy Homes: Oral Understandings and the Practice of Archaeology in Nineteenth- and Early Twentieth-Century Ireland

Ringforts, the most numerous archaeological monument in the Irish landscape, have a dual character as places of early medieval habitation and as supernatural points of access to a fairy Otherworld. In my paper, I examine how these understandings interacted with, challenged and reinforced each other in the nineteenth and early twentieth century, and how oral perceptions had a significant if generally unacknowledged role in determining supposedly scientific archaeological perceptions of these monuments.     

Shifting monument production chains and the implications for gravestone design on Prince Edward Island, 1820–2005

This paper examines changing gravestone design in Prince Edward Island (PEI) (1820–2005) and relates these changes to changing modes of production in the monument industry. Information from field surveys, newspaper advertisements and business correspondence reveals how supply-side factors helped shape the morphogenesis of the island's cemetery landscapes. Among these, different sources of raw materials and manufacturing innovations over time resulted in the use of harder, more durable types of stone. With these changes, gravestone production and design moved increasingly away from local monument works towards off-island producers in Vermont, New Brunswick and Nova Scotia. Since the early 20^th century, PEI's gravestone suppliers vertically integrated along Fordist mass-production lines and increased choices available to local monument sellers and their consumers.     

Wareham West Walls

THE ARCHAEOLOGICAL WORK which has been carried out in Norwegian towns in recent years has resulted in the medieval town being regarded as a single monument. Permanent excavation offices have been established in the most important medieval towns. Survey accounts of archaeological data and other relevant information form important tools for safeguarding archaeological interests, both in connection with excavation and with the administrative co-ordination of the clauses in the Cultural Heritage Act. The large number of excavations in recent years has left little time for research but this is now being given the highest priority.

Bronze Age landscape dynamics: spatially detailed pollen analysis from a ceremonial complex

The late Neolithic and early Bronze Age are periods marked by the construction of conspicuous concentrations of ‘ritual’ complexes, used for funerary rituals, seasonal gatherings and communal activities. Understanding the environmental context of monuments may provide detailed insights into relationships between the physical environment and the activities undertaken at individual monuments. Raised burial mounds (barrows) are generally assumed to have been constructed in open landscapes (the so-called ‘landscape openness’ hypothesis) thus rendering them highly visible in the surrounding landscape. This paper seeks to test to what extent vegetation (and in particular openness) around a dense concentration of barrows was actively managed, using three pollen sequences in close spatial juxtaposition to the archaeology. The local vegetation histories, supported by radiocarbon dating, demonstrate spatial differences in vegetation pattern both during the time of monument construction and use (c. 2000–1500 cal BC) and during subsequent periods. They do not support the ‘landscape openness’ hypothesis. This suggests that there is no single ‘blueprint’ for vegetation structure on and around these types of monument complexes. There is no evidence for major restructuring of the landscape during the early Bronze Age. The data describe a major transformation of the vegetation around 1500 cal BC (the Middle Bronze Age) in an area not known for archaeology of this date. This serves to emphasize the role of palaeoecology in augmenting the archaeological record of landscape re-organisation and transformation in prehistory.     

Use of robust methods to determine quadratic surfaces: application to heritage

3D surveys of archaeological elements and the construction of virtual models enable us to reconstruct historical sites. They provide useful data to select specific building processes.Photogrammetry and Terrestrial Laser Scanning (TLS) are the most common techniques to obtain synthetically heritage models. These techniques provide massive data which can only be managed by replacing them by primitive shapes, thereby obtaining more simple models and the explicit geometry of the element. Statistical and robust methods are used for this substitution, thereby avoiding the common errors due to measuring. Of these methods, the most widely used are the least-median-of-squares (LMedS) and the RANSAC method.Another computation method consists in recursive processes based on evolutive-type algorithms to adjust the model to the data captured.This paper describes two surface computation methodologies to determine the modelling of a column shaft located in temple G of the archaeological park of Selinunte (Sicily).     

Laser scanning for the documentation and management of heritage sites within the Emirate of Fujairah,United Arab Emirates

The Emirate of Fujairah in the UAE has many important cultural and archaeological sites. These include the Fujairah and Al‐Bithnah forts and the Al‐Bidyah Mosque. With increasing tourism patronage and development of major infrastructure projects in and around Fujairah, these sites are increasingly under threat. Their present condition requires careful mapping for proper management and future preservation efforts. This paper presents a research project that is developing a method for surveying and recording important archaeological sites. Using terrestrial laser scanning (TLS), a number of surveys were undertaken in and around the emirate. These surveys enabled a documentation of their present condition and will form an ongoing baseline study to monitor the impact of increased tourist patronage and climate change at these sites. We also investigate and make basic comparisons between our approach and the Structure from Motion (SfM) technique.     

MONUMENTS AND SOCIAL COMPLEXITY: A NEW LINE OF ENQUIRY?

Summary. Studies of prehistoric monuments have suggested that there may be a relationship between the amount of labour needed to build them and the complexity of contemporary society. To some extent such work has been influenced by the rich ethno-historical record of the Polynesian chiefdoms. This article compares the role of large monuments in Polynesia with ethnographic evidence describing monument building in an Indian tribe. It concludes that an important contrast between the two examples is that in simpler societies monument building may be essentially an 'event', whilst in more complex societies monuments can be maintained for a substantial period after their erection.
Similar contrasts can be found in the archaeological record in Britain and suggest that whilst Neolithic earthworks may have made greater demands on human labour, it was only in the Iron Age that society possessed the capacity to undertake regular maintenance of large monuments.     

Monitoring the Environmental Risks Around Medinet Habu and Ramesseum Temple at West Luxor,Egypt, Using Remote Sensing and GIS Techniques

Today, the preservation of cultural heritage is a pressing issue especially for territories subjected to a long period of human action that could adversely influence environment and heritage properties, thus producing a deterioration of archaeological features and alteration of historical landscape. In this paper, the environmental risks and their effects on preservation issues are investigated for the archaeological area of the Luxor city (south of Egypt) where the most famous Temples in Egypt are located. A comprehensive analysis has been conducted for the Ramesseum and Medinet Habu temples considering their building material and characteristics, environmental (geological and hydrological) setting, and past and ongoing changes around the monument areas. Satellite multitemporal images have been used to detect all the changes mainly linked to the expansion of urban and agriculture areas. Results from the analysis conducted along with in situ investigations have suggested that many of the environmental problems around the archaeological areas are coming as a result of urban and agriculture sprawling. Both of them strongly influence the distribution in the levels of groundwater which along with temperature are considered as the main causes of the deterioration process affecting the Medinet Habu and Ramesseum temple. The degree of weathering damage appears to be much more dependent on exposure characteristics of the investigation areas, especially as related to salt weathering processes. Innovative solutions to support the preservation of these temples are herein presented and discussed.     

Paper 1: The Coudenberg Archaeological Site in Brussels: The Stakeholders Involved in the Renovation Process

Abstract

The last material evidence of the former Palace of Brussels, the Coudenberg archaeological site, is situated at the heart of the city, constitutes a remarkable part of its heritage, and has been listed as a legally protected monument. Following the redevelopment of the Royal Quarter in the eighteenth century, the successive archaeological discoveries of the last twenty-five years, and the progressive growth of the areas accessible to the public, the various components of the site have not all been preserved in the same condition. The work involved in developing such a complex has already necessitated considerable resources, and still requires more today. The owners, the City of Brussels and the Brussels-Capital Region, as well as the site’s managers, the not-for-profit association ‘Palais de Charles Quint’, are continuing their programme of developing, promoting, and preserving the remains in order to hand down this important historical evidence to future generations.     

Gazetteer of small‐scale monuments in prehistoric Hadramawt,Yemen: a radiocarbon chronology from the RASA‐AHSD Project research 1996–2008

This paper provides a new, interpretive gazetteer and chronology of Hadramawt’s highland monuments based on results from archaeological survey and test excavations by the RASA‐AHSD (Roots of Agriculture in southern Arabia‐Arabian Human Social Dynamics) Project. With the exception of a few incidental sightings and an unpublished pipeline survey, the prehistoric record of southern Yemen’s highland plateau has been largely unknown. There are few settlements, so that understanding human landscape history must begin with the numerous small‐scale stone monuments left by mobile people. With examples representing monuments from the fifth, fourth, third and first millennia BC, the corpus of small excavations and radiocarbon dates reported here provides the first guide to the monument types of South Arabian highlands. Monument building began under more moist conditions and appears to have commemorated animal sacrifices long before commemorating mortuary rites and interment. There appears to be a temporal break of 1000 years before the widespread and varied practices of Bronze Age tomb construction, which lasted through the third millennium BC. After another break in monument construction, tombs were reused in the first millennium BC, sometimes with successive ritual visits. The data presented offer new material for the interpretation of the lives and activities of prehistoric pastoralists throughout the Holocene.     

GPR and inductive electromagnetic surveys applied in three coastal sambaqui (shell mounds) archaeological sites in Santa Catarina state, South Brazil

In this article, GPR – Ground Penetrating Radar and inductive electromagnetic (EM38 equipment) results are presented for three archaeological sites of shell mounds located between Laguna and Jaguaruna cities, mid-southern coast of Santa Catarina state, Brazil. The Jabuticabeira II, Santa Marta IV, and Encantada III sites were studied. These sites consist of carbonate shell mounds built by societies that inhabited this region during the pre-colonial period (7.5–1.3 ky BP). Geophysical responses obtained in these archaeological sites had allowed the identification of anomalous regions related to archaeological point targets as well as continuous targets, correlated to the shell mound's structure and buried geologic features. GPR numerical modelling studies were done in order to evaluate the performance of the GPR method in relation to materials found in that environment, besides helping interpretations of real results. The synthetic GPR model was a good match with real data obtained in the field. So, the real and synthetic results serve as a reference guide to direct excavation activities in these archaeological and geological structures. In the Jabuticabeira II shell mound, lithic materials and burials were found amidst archaeological layers characterized by sediment rich in organic material, ferruginous concretions, and loose shells. In the Santa Marta IV archaeological site, a concentration of ceramic materials, burials and fireplaces were found. In the Encantada III site, a strong anomaly characterized by a hyperbolic reflection was related to the presence of a silicified tree root; a great example of ambiguity in shallow geophysics interpretation in archaeological applications. Results functioned as a guide to archaeological excavations, allowing cost and time reduction as well as contributing to improve the knowledge of these archaeological sites situated in southern Brazil.
