Interpreting the past: Presenting archaeological sites to the public

Abstract

A wide range of methodologies have been applied to promote the conservation of exposed and managed archaeological sites, including shelters. Commonly used as a protective measure in many areas of the world, shelters are not as common in the USA. In addition there have been few efforts to evaluate scientifically their use and efficacy. As a response to the recognized need to further scholarship and dialogue about shelters, a colloquium on the topic was held in Tumacacori, Arizona, in January 2001. The colloquium goals focused on research, exchange of information, the advancement of methodological approaches, incorporation of sheltering concepts into planning processes and identifying field needs. To achieve these aims, the following four themes were developed:

? deciding to shelter

? establishing conservation, design and construction criteria

? designing and constructing shelters

? evaluating shelter performance.

The colloquium followed a course of presentations, site visits and a final plenary session summing up the issues put forth. Participants represented a cross-section of disciplines and a range of international experiences.     

Promotion of a neglected heritage at Stone Age sites in the Western Cape,South Africa

Abstract

All archaeological sites in South Africa are protected in terms of the National Monuments Act, yet some have been badly damaged by vandals, unauthorized collectors and the effects of natural and anthropogenic erosion. In an effort to minimize such damage, the policy in the past has been either to restrict access or to keep a low profile, in relation both to rock art and excavated sites. Coupled with the fact that, in the past, the precolonial period has not been included in school history curricula, this policy has had a negative effect. South Africans generally have a limited knowledge of the results of research on rock art and archaeology and are not aware of the legislation. Furthermore, there is no infrastructure and no market for promoting such sites for tourism. The National Monuments Council has identified the need for public education in this field within a broader goal of promoting a common heritage for all South Africans in this time of political change. Three examples of recent active intervention are given in this paper. Stone Age living sites at Nelson Bay Cave and Matjes River rock shelter have been developed as local attractions, and protective conservation measures have been put into practice at rock art sites that are open to the public in the Western Cape.     

Life and death at precolumbian Lavoutte,Saint Lucia,Lesser Antilles

Abstract

The Caribbean archaeological record requires immediate attention and protection. Development and natural forces have impacted archaeological sites, destroying or severely damaging them. The precolumbian site of Lavoutte, located in northern Saint Lucia, has been known as a major Late Ceramic Age (a.d. 1000–1500) settlement since the 1960s, but it has been damaged over the past decades by both natural and human processes. Multidisciplinary field and laboratory methodologies were implemented during a rescue project at the site from 2009 to 2010. This paper presents the results of collaborative efforts between local and international organizations. The first goal was to demonstrate the importance of protection and rescue of endangered archaeological sites. Secondly, we aimed to show that by adopting a multidisciplinary approach including artifact analysis, bioarchaeology, paleoenvironmental reconstruction, and geochemistry, severely damaged sites can be of significant informational value.     

Uncovering a Painful Past: Archaeology and the Holocaust

Abstract

Places connected to the Holocaust, and the physical evidence that lies within them, survive as reminders of the crimes perpetrated by the Nazis. Both the treatment of these sites and attitudes towards them have varied considerably in the years since the Second World War. In recent years, a number of archaeological investigations have been instigated by curators at Holocaust sites in a direct attempt to enhance visitor experiences and education programmes. Archaeologists have initiated investigations at other forgotten and dilapidated sites in an attempt to raise awareness of these places. This paper will discuss two case study sites where archaeological investigations have been undertaken and where attempts have been made to inform conservation, heritage management, and education strategies. It will highlight the various challenges that may arise in the course of developing dissemination tools and discuss strategies that have been adopted to account for them. Specifically it will focus on how archaeologists can present novel means by which to locate, record, and re-present the physical evidence of the Holocaust and how they can tell the stories of difficult heritage sites even when traditional forms of memorialization/muzealization is not wanted or practical.     

Seismic Refraction at Ancestral Puebloan Sites on the Pajarito Plateau,New Mexico

Abstract

Geophysical techniques can be used for non-invasive surveys at archaeological sites. One under-utilized technique, seismic refraction, has many potential applications. It is an inexpensive, efficient way to characterize subsurface deposits, especially at sites with shallow accumulations over bedrock. Archaeologists and geophysicists participating in the Summer of Applied Geophysics Experience from Los Alamos National Laboratory and Bandelier National Monument on the Pajarito Plateau in northern New Mexico characterized Ancestral Puebloan sites (A.D. 1200–1450) using this technique. We provide an overview of how seismic refraction works and demonstrate the applicability of seismic refraction for identifying buried archaeological features such as communal structures and walls.     

Site Conservation in Morocco: The Emergence of a Practice at Aghmat

Abstract

It is still uncommon for foreign and national archaeological excavations in Morocco to include architectural or site conservators during the excavation and post-excavation periods. The few existing examples of conservation have all been carried out long after the site or the building had been excavated. The site conservation activities during the Aghmat excavations in summer 2006 illustrate how the presence of archaeological conservators, advising the archaeological team and implementing urgent interventions, has ensured a safe excavation and has contributed to the preservation of the physical integrity of the excavated buildings. The excavation of the imposing archaeological features of the medieval bath of Aghmat provided the first opportunity in Moroccan archaeology for Moroccan archaeological conservators to be involved in condition assessment, planning, and provision of conservation activities to preserve the bath.

The primary aim of this paper is to present the site conservation experience in the Aghmat project, which is the first such project to be initiated during an excavation, and to be conducted mainly by a Moroccan team; it aims also to highlight the conservation procedures adopted and to incite discussion.     

A botanical approach to the planning of archaeological,parks in Italy

Abstract

The positive role of plants in archaeological areas, as well as the enegative action of their roots in causing structural damage, are summarized in this paper. The traditional approach to the planning of vegetation in Italian archaeological areas is briefly described. A general philosophy for botanical projects in these sites is proposed, taking into account ecological, historical and conservation parameters. The principal aims of the suggested approach are: protection of the naturalistic, historical and landscape features of the existing site, in so far as they are compatible with the archaeological structures; and the introduction of new elements, in keeping with the original landscape, which exploit shelter effects or improve microclimatic and soil characteristics, and are also ‘ornamental’. The criteria for evaluating the characteristics of the site from the naturalistic and from the historical and landscaping points of view are explained. Also briefly. discussed, are congruity with the history and character of the site, overall compatibility with archaeological structures, usefulness for reconstructing specific environments, conservation Value for the site and aesthetic and economic criteria for the selection of species to introduce.     

‘I Felt Connected to a Past World’: A Survey of Visitors to Colonial Archaeological Sites Conserved In Situ in Australia and New Zealand

Abstract

While there is extensive international literature on the technology and techniques of archaeological conservation and preservation in situ, there has been only limited discussion of the meanings of the places created and the responses they evoke in visitors. Experience in Australia and New Zealand over the past decade suggests that the conservation of colonial archaeological remains is today seen as a far more desirable option, whereas previously many would have suggested that this kind of conservation was only appropriate in ‘old world’ places like Greece and Italy; and that the archaeology of the colonial period was not old enough to be of value. This paper discusses a recent survey of visitors to colonial archaeological sites which reveals some of the ways in which these archaeological remains are experienced, valued, and understood, and gives some clues as to why conservation in situ is an expanding genre of heritage in this region. The visitors surveyed value colonial archaeological sites conserved in situ for the link they provide to place, locality, and memory; for the feeling of connection with the past they evoke; and for the experience they provide of intimacy with material relics from the past. This emphasis on the affective qualities of archaeological remains raises some issues in the post-colonial context, as it tends to reinforce received narratives of identity and history, and relies on the ‘European’ antiquarian appreciation of ruins — making the urban environment more like Europe by creating evidence of similar historical layering.     

Some Issues on the Management of Archaeological Sites in Mainland China

Abstract

The conservation of archaeological sites in mainland China has not attracted much academic and public attention until recently. However, after the 1990s, both the Chinese government and academia have been increasingly concerned with the management of archaeological sites, as illustrated by the introduction of national guidelines (China Principles) and the establishment of research centres in universities and research institutes. Economic development and related social needs are major driving forces behind this phenomenon, while the impact of globalization on academic development in China cannot be denied. However, the natural and social environments in mainland China, as well as the characteristics of archaeological sites, differ from other countries, and whether international principles regarding conservation and management of archaeological sites are applicable to China needs to be considered. While it is a challenging task for mainland Chinese scholars to find suitable strategies to conserve and manage hundreds of thousands of archaeological sites, the problems and experiences in the process of applying international principles to China may provide valuable lessons, not only for Chinese scholars but also for scholars in other areas.     

Nydam Mose: In Situ Preservation at Work

Abstract

The site of Nydam Mose saw the beginning of systematic research into in situ preservation of waterlogged archaeological sites on land at the National Museum of Denmark. In the past fifteen years a generic approach to in situ preservation of archaeological sites has been developed based on this research. This article is primarily a review of this generic approach, summarizing the methods and results with particular reference to the published results from the investigations in Nydam Mose.     

The Tenth Conference of the International Committee for the Conservation of Mosaics. Conservation: An Act of Discovery

Abstract

The Herculaneum Conservation Project has approached the conservation of a large-scale archaeological site (Herculaneum, Italy) suffering widespread forms of decay in two different ways: 1) with a site-wide campaign addressing conservation problems in areas most at risk and 2) with a case-study project for one urban block (Insula Orientalis I ) exploring some of the complex conservation challenges in more detail. One of these challenges is how to approach the repair of existing roofing and how to design new forms of protective shelter for those spaces that have never been covered. Short-, mid- and long-term solutions for the repair and substitution of existing roofing are being tested as part of the site-wide campaign, while in the case-study area more enduring solutions (new mid- and long-term) for new shelters are being trialled.     

On the challenges and benefits of indoor archaeology: 15 years at the Archeodome (Mitchell Prehistoric Indian Village,South Dakota)

Abstract

Field archaeology is normally associated with outdoor excavation and exposure to the natural environment. Archaeological excavations have adapted to a wide spectrum of these conditions, but the recent prominence of archaeological sites as tourist attractions and educational facilities has occasionally led to dramatically different environments for the archaeological recovery, interpretation, and preservation of evidence, including facilities that permit indoor excavation. This article explores 15 years of experience at the Mitchell Prehistoric Indian Village in South Dakota. An “Archeodome” covering part of the site represents a non-traditional excavation and preservation environment that presents considerable benefits and challenges for archaeologists. The structure provides the basis for evaluating the nature of indoor excavation within its archaeological and educational context and provides a cautionary note for archaeologists, heritage groups, tourist boards, and others interested in the preservation of archaeological sites. Though this article focuses on the Mitchell site, the information reported has broad implications for sites where structures cover archaeological deposits.     

Methodology,consetvation criteria and performance evaluation for archaeological site shelters

Abstract

The many intersecting issues that arise when deciding whether to shelter an archaeological site should be approached using a values-based methodology, one that has demonstrated its validity arid practical worth in conservation over recent decades. Nonetheless, pitfalls abound in the decision-making process and in establishing effective conservation criteria which should be based principally on a thorough understanding of the threats to the resource and the specific deterioration mechanisms operating, with the objective of creating a shelter that will preserve the site's identified values. An aspect that has received almost no attention in the past is evaluation of a shelter's performance, both qualitative and quantitative, in preserving the site. It is urged that this receive priority when establishing the conservation criteria during the initial phases of a sheltering project. Issues are illustrated from a range of diverse sites, including a number of published shelters. The paper first looks at the examples of the Laetoli (Tanzania) and Lark Quarry (Australia) trackway sites in the context of decision-making and conservation criteria, and then discusses two examples of evaluation: one quantitative, using an experimental shelter and the other discussing publications on a petroglyph site shelter.     

In Situ Preservation of Ancient Floor Mosaics in Turkey

Abstract

As stated in the Burra Charter (1979) ‘A building or work should remain in its historical location. The moving of all or part of a building or work is unacceptable unless it is the sole means of ensuring its survival’. This statement has been neglected many times during rescue excavations in Turkey (e.g. Zeugma), whereas the destruction of ancient floor mosaics caused by lifting, especially when carried out by incompetent or inexperienced personnel at systematic archaeological excavations, has steered the authorities desire to preserve them in situ. However, due to the lack of conservation professionals and insufficient resources for conservation, it becomes a difficult issue to provide an effective preservation scheme for archaeological excavations. This paper aims to discuss this important issue in terms of the national legislation, preventative and interventive conservation approaches at various sites, exhibition and maintenance of mosaics, as well as the training of conservation technicians in Turkey.     

Complications and Effectiveness of In Situ Preservation Methods for Underwater Cultural Heritage Sites

Abstract

Underwater Cultural Heritage (UCH) as an outstanding division of the cultural heritage of humanity appears to be crucial and complicated when more general issues regarding preservation and conservation are raised. The essence of in situ preservation should be equally discussable for any kind of archaeological remains; on land or underwater.

There is a long history of different methods and concepts of intervention in a variety of sub-aquatic archaeological sites; from shipwrecks to submerged settlements. This paper will present an introduction to different techniques and theories of preservation and conservation of underwater cultural and archaeological sites since this kind of heritage has scientifically been explored and studied. A range of different preservation methodologies, from total or partial transference inland, to preservation underwater, will be compared; the advantages and disadvantages of each option will be highlighted. Different examples of international best practices will be illustrated. Different types of in situ conservation/protection will be explained and categorized. Furthermore, there will be a focus on the UNESCO Convention of 2001 on Conservation and Preservation of UCH, where the in situ conservation option has been recommended.

Moreover, the technical issue for preservation of UCH sites, either in situ or after displacement, will be explained. The implication of relocation for different sorts of sites and materials will be argued; for example, cases where some sites, such as shipwrecks, would more easily be displaced compared with submerged settlements, villages, or ports.

Finally, by stressing that the state of ‘being underwater’ makes many sites qualified to be regarded as UCH, the in situ preservation approach will prevail that this state is maintained.     

The decision to shelter archaeological sites Three case-studies from Sicily

Abstract

The decision to provide a protective shelter for exposed archaeological remains is illustrated by examining case studies of three sites in Sicily that were provided with protective measures in the 1950s. The three protective shelters were designed by the same architect, Franco Minissi, for the sites of Gela, the Villa Romana del Casale (Piazza Armerina) and Heraclea Minoa. His work on protective shelters is viewed in the broader context of the development at that time in Italy of Cesare Brandi's theory of restoration and of Minissi's own philosophy of 'musealizzazione' for the protection of historic sites and their integration into contemporary society.     

Conserving sites on the Central Asian Silk Roads: the case of Otrar Tobe,Kazakhstan

Abstract

Conservation activities have been carried out during the four years of the UNESCO project for the Preservation and Restoration of the Ancient City of Otrar, an archaeological site located in a loess clay area in southwest Kazakhstan at the confluence of Syr Darya and Arys rivers. The paper focuses on certain conservation activities carried out at the site, including documentation of observed deterioration phenomena, authentication of surviving mudbrick and fired brick structures, and the repair of structures using an earth-based repair mortar specially developed for the site. The paper summarises the main achievements of the project in terms of conservation, documentation, training, promotional activities and master plan preparation.     

An Integrated Survey of Roman Urbanization at Potentia,Central Italy

Abstract

Our research contributes to the study of Roman urbanization in the Italian peninsula, both in the central Adriatic area and beyond. It focuses on the integrated use of archaeological field methods and non-destructive techniques. The study of the urban layout of the city of Potentia is an example of the use of low altitude aerial detection combined with regular grid-walking and geophysical survey to intensively investigate abandoned classical town sites. Information can be combined in a new approach to the study of urbanization processes in the heartland of the Roman world, and this integrated methodology can be applied to any large archaeological site with regular patterning such as orthogonal street layouts and planned civic centers.
