Preserving Archaeological Remains In Situ: Three Case Studies in Trentino,Italy

Abstract

The paper presents the results of the restoration and conservation work which has been carried out in three archaeological areas in the Autonomous Province of Trento. The areas, which have been opened to the public for more than ten years, are the open-air archaeological site of Monte S. Martino, Roman Tridentum (an underground site under the historical city centre of Trento), and Fiavé (a pile dwelling site in a peat bog). These areas present very different environmental characteristics and have therefore required different interventions according to their speci?c situation.

In order to reduce maintenance and extraordinary costs, appropriate conservation of the archaeological remains is required. This consists of methodologies of conservation according to the characteristics of the environment; continuous monitoring systems and indirect preventive intervention; and annual maintenance planning.     

Integrated Investigation,Assessment, Intervention Design,and Implementation as a Model for Conservation Practice

Abstract

The Bibi Jawandi Monument Complex is a site of 15th-century partially collapsed glazed masonry tomb structures located in the ancient city of Uch Sharif, in Pakistan. Conservation of the striking monuments has involved an integrated approach comprising investigations of building materials, structural stability, geotechnical characteristics, as well as management capacity and infrastructural considerations of the site and surrounding city. A primary assessment of the site’s aesthetic, artistic, historical, social, and scientific significance guided the development of interventions and conservation priorities. The holistic approach to the protection of the site, in relation to the surrounding historic town, is one of the first such integrated conservation projects to be undertaken in Pakistan and posed numerous conservation challenges. Work is ongoing and continues, relying on intermittent funding, but the project and site serve as a model in the region for thorough assessment informing conservation decision-making.     

Investigating absence: Assessing the cumulative effects of casual collecting at a 19th century Bahamian plantation

Abstract

Recent archaeological work at Prospect Hill, a 19th century plantation in the Bahamas, revealed artifact patterns that are inconsistent with expectations for a plantation site. The quantity and quality of artifacts in residential areas associated with the planter family and the enslaved population were inverted and suggest significant post abandonment changes. The site of Prospect Hill has been a destination for tourists and student groups since the mid-20th century, and the areas of the site most accessible to these visitors are also those with surprisingly low artifact counts. I investigated the possibility that regular visitation involved casual collecting using historical data as well as artifact assemblages from archaeological work at Prospect Hill. My analysis suggests that the archaeological record has been altered significantly through casual, opportunistic collecting, and it offers insights for identifying casual collecting elsewhere.     

A Qualitative Approach for Assessment of the Burial Environment by Interpreting Soil Characteristics; A Necessity for Archaeological Monitoring

Abstract

Modern-day archaeological monitoring is often hampered by lack of money, lack of time, inadequate measuring equipment, and lack of insight in the conservation potential of a site.

Although in modern archaeological excavations soil characteristics are noted (colour, texture, groundwater level, and sometimes mineralogy), these characteristics are mainly used for the interpretation of a site. However, by looking to these characteristics from a conservational view eventually combined with the conservation status of the archaeological objects, much can be learned about the burial environment. This is essential for optimizing archaeological monitoring.

Degradation processes result from the change of reactive phases in the soil or the site. Reactive phases are soil components such as organic matter, sulfides, iron(hydr)oxides and carbonates (chalk, shells), and, if present, components in the ground or interstitial water such as hydrogen ions and sulphate. The presence of these phases can easily be established by the archaeologist or soil scientist in the field. We propose a simple field-based method for assessing degradation processes essential for in situ preservation and monitoring.     

Designing protective structures at archaeological sites Criteria and environtnental design tnethodology for a proposed structure at Lot's Basilica,Jordan

Abstract

This paper sheds light on the need to assess the efficacy and performance of protective structures at archaeological sites according to design criteria derived from various elements in heritage management processes. The paper also focuses on the use of architectural design methodologies that essentially correspond to physical conservation requirements at archaeological sites. The paper, in effect, introduces climatic approaches to the design of protective structures at archaeological sites. It further illustrates the value of computer-based environmental simulation and modeling tools in the design phase of projects. Despite their limitations, these tools help guide design processes, and generally indicate future conservation effectiveness and performance of protective enclosed structures at archaeological sites.     

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.     

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.     

Preservation of Earthen Sites in Remote Areas: the Buddhist Monastery of Ajina Tepa,Tajikistan

Abstract

The Buddhist monastery of Ajina Tepa is one of the most significant in Central Asia as it was fully excavated using up-to-date archaeological methods and was extensively documented. The site is a sophisticated blend of earthen architectural forms, sculptural detail and wall painting decoration, all of which are unique in the area. The site is located in south Tajikistan along the Vahsh valley, about 13 km east from the modern city of Kurgan Tybe.

The aim of the paper is to give an overview of the UNESCO/Japan Trust Fund project 'Preservation of the Buddhist Monastery of Ajina Tepa, Tajikistan (Heritage of the Ancient Silk Roads)'. The paper describes the historical background, the main conservation threats, the analytical work in the selection of repair material, the preparatory work before conservation, the documentation activities, and the conservation work carried out at the site.     

Archaeology and conservation at Herculaneum: from the Maiuri campaign to the Herculaneum Conservation Project

Abstract

This article looks at two periods in the history of the archaeological site of Herculaneum (Italy) and the role of the archaeologist there. Amedeo Maiuri was in charge of the first major excavation campaign that uncovered the site from 1927 to 1961, but was also responsible for the site's restoration, presentation and maintenance. Much can be learnt from his approach, particularly with regard to site management – a fixed team of specialists continuously cared for the site – and his creation of what was effectively an open-air museum. The second example looks at the author's experiences with the Herculaneum Conservation Project, where the emphasis is on conservation interventions rather than excavation, but where the archaeologist has an important role in the conservation team and also has the opportunity to make new archaeological discoveries. The article concludes that the role of the archaeologist must evolve to include a professional responsibility for archaeological heritage that extends beyond its excavation.     

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.     

Mounds,Towns, and their Surrounds: An Archaeological,Historical, and Geophysical Approach to Burial Mounds,Residential Space,and Cultural Landscapes of the Late Woodland Springwells Site (a.d. 800–1400) at Historic Fort Wayne,Detroit

Historic Fort Wayne is located on the Detroit River in a landscape of heavy industry and marginalized urban neighborhoods (figure 1). Geophysical survey south of the Fort Wayne Mound—a Late Woodland Period burial mound enclosed by the Fort—indicates that pre-contact residential structures may be preserved at the site. Residential sites with mortuary monuments are uncommon in southeastern Michigan and represent an opportunity to better understand variation in Late Woodland settlement. Our approach combines existing archaeological research, historical records, and non-invasive geophysical survey in a culturally sensitive Native American site context presently unavailable for conventional archaeological excavation. We examine archaeological and historical records from Springwells and Late Woodland period settlements in the region to contextualize geophysical evidence from the site. The research prioritizes protection of Native American heritage sites in urban contexts together with ongoing archaeological interpretation of the Late Woodland cultural Landscape.     

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.

Paper 2: Climatic Study of the Underground Archaeological Site Coudenberg

Abstract

The excavation and valorization of subterranean archaeological remains, and eventually opening a site to the public, required a proper management and conservation strategy. This strategy was based on the evaluation of the delicate balance between the requirements for public health and safety, and the protection of the archaeological remains from future degradation. Controlling the climate can be essential for a preventive conservation strategy, which can be defined as an indirect action to increase the life expectancy of the archaeological remains, and by doing so keeping them in a preferred state of conservation to mitigate damage and/or deterioration.

Potential risks and possible interventions are outlined to avoid climatic conditions which are in conflict with the requirements for the visitors’ comfort while preventing damage phenomena to the materials.

The paper summarises the main achievements of the project in terms of conservation, documentation, training, promotional activities and master plan preparation.     

‘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.     

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.     

Showcasing Maritime Heritage Artefacts for the Benefit of the Tourist Industry in Malaysia

Conservation in urban areas is an active issue, but in remoter areas historical remains are neglected by both public and government. Conservation of maritime archaeological sites is fast becoming important elsewhere. Acknowledging the importance of conservation for other types of historical sites, this paper addresses the need for conservation of the as-yet-unknown number of maritime archaeological sites in Malaysia. This will take time and continuing effort. Malacca Maritime Museum is a case-study, built specifically for showcasing artefacts from shipwrecks. The first such museum in Malaysia, it has benefited tourism as well as preserving objects and educating the public.

Integrating Archaeological Heritage into Towns and Settlements

ABSTRACT

This article explores factors concerning the urban integration of archaeological heritage in towns and settlements. Archaeological heritage refers to visible, immovable archaeological remains (such as the remains of buildings or structures), sites, and areas (larger complexes). As part of the multidisciplinary process of archaeological heritage management, based on understanding the significance of a site and the goal of enhancing and preserving archaeological heritage in situ, urban integration and its determining factors have not been the subject of systematic research. The present study is derived from the application of deductive research based on theoretical assumptions validated by a qualitative survey. Research has identified 17 factors as the basis for the urban integration of archaeological heritage in towns and settlements. These factors represent a theoretical and practical contribution not only to urban planning but also to archaeological heritage management.
