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.     

Rewilding – A New Paradigm for Nature Conservation in Scotland?

Abstract

Rewilding is a strategy for the conservation of complete, self-sustaining ecosystems, primarily involving the protection and, where necessary, reintroduction, of populations of keystone species in large, connected reserve networks. A potential method of preserving ecosystem functions and biodiversity, it is now receiving a great deal of practical and political attention, particularly in North America. In Scotland, where many native species have been extirpated in the relatively recent past, rewilding has clear relevance and may provide an overarching set of objectives for current programmes of native woodland restoration and species reintroductions. Nevertheless, rewilding is not widely used as a term or strategy in Scottish conservation. This review considers the development of the concept and its possible application in Scotland, and identifies substantial scope for rewilding, in terms of the restoration and protection of large areas of wild land, and of the reintroduction of native species which have been driven to extinction by human activity. As the environmental, social and economic benefits which are likely to result from a programme of rewilding in Scotland outweigh the potential drawbacks, the adoption of rewilding is recommended as one aim of environmental policy.     

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.     

Access relative to need for community conservation funding in Australia

ABSTRACT

In a climate of scarce resources for heritage preservation, there is a need to develop principles and methodology for assessing and responding to inequity within the conservation sector. This paper focuses on spatial, or geographic, barriers as one factor determining the accessibility of conservation services. While the case study focuses on the conservation and management of collections of cultural material in Australia, the methodology is globally relevant for advancing the equitable distribution of heritage and conservation resources according to need. Using a statistical analysis of the spatial distribution of 1323 local heritage conservation projects that have been funded by the National Library of Australia’s Community Heritage Grants Program from 1994 to 2017, this study provides a measure of the spatial equality of conservation in Australia. Spatial distribution analysis indicates that the majority of projects funded are located in major cities, with fewer projects funded in regional, remote and very remote areas. An ‘access relative to need’ approach is proposed to counter the current centralisation of the conservation industry. Of particular relevance for international readers is the potential for this methodology to frame studies of the impacts on heritage resulting from climate change and extreme weather events.     

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.     

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 ISCR Project ‘Restoring Underwater’: An Evaluation of the Results After Ten Years

Abstract

The project ‘Restoring Underwater’ launched and conducted by the Underwater Archaeology Operations Unit of the Istituto Superiore per la Conservazione ed il Restauro (ISCR, Rome, Italy) is aimed at the study and the experimentation of instruments, materials, methodologies, and techniques for the restoration, conservation, and in situ display of ancient submerged artefacts. The project commenced in 2001 with the restoration of the vivaria of the Roman villa of Torre Astura (Nettuno, Rome), since 2003 the main subject of researches has been the submerged archaeological site of Baiae (Naples, Italy), where, over the years, the restoration of sectors of certain buildings in the protected marine area has been carried out: the Villa con ingresso a Protiro, the Villa dei Pisoni, the Via Herculanea, and the Building with porticoed courtyard near Portus Iulius. In 2007, in 2009, and in 2010 three new archaeological targets have been added to the research: a group of nine cast iron cannons discovered offshore the coast of the Marettimo Island (Sicily, Italy), the Roman wreck carrying a load of sarcophagi discovered off the coast of San Pietro in Bevagna (Taranto, Italy), and the traditional fishing boat recently discovered off the cost of Martana Island (Bolsena Lake, Italy).

The purpose of this paper is to sum up the work in progress and the results of these ten years of the project. The paper will shows as the conservation and museum display in situ of underwater heritage must not just be considered an opportune choice but may in itself provide a strong stimulus for experimenting new materials and technologies as well as representing a factor in the socio-economic development of the communities concerned, as shown by the example of Baiae.

Authenticity and heritage conservation: seeking common complexities beyond the ‘Eastern’ and ‘Western’ dichotomy

ABSTRACT

This article challenges the claimed gulf between ‘Eastern’ and ‘Western’ concepts and approaches to heritage conservation through an analysis of the common complexities surrounding authenticity. The past few decades have witnessed an important critique of ‘Eurocentric’ notions of heritage conservation, drawing on ‘non-Western’, particularly Asian, contexts. Authenticity has been a core principle and defining element in this development. Endorsed by a series of charters and documents, a relativistic approach emphasising the cultural specificity of authenticity has been introduced alongside the European-originated materialist approach in international policy and conservation philosophy. However, the promotion of Asian difference has also contributed to an increasingly entrenched and unproductive dichotomy between ‘Eastern’ and ‘Western’ approaches to heritage. This article reveals common complexities surrounding authenticity in two countries crosscutting this dualism – China and Scotland. Drawing on a number of ethnographic projects, our analysis identifies themes that characterise the experience of authenticity across different cultural contexts. It contributes to a more nuanced understanding of the evolving relationships between heritage conservation and contemporary societies with important implications for global heritage discourses and collaborative ventures crosscutting ‘Eastern’ and ‘Western’ contexts.     

Mobilising non-participant youth: using sport and culture in local government policy to target social exclusion

ABSTRACT

The role of sport and cultural practices in policy initiatives tends to be assessed in both cases in terms of their assumed social benefits. However, the areas of sport and culture are often understood separately in research. Through an analysis of interviews with key local policy-makers and civil servants in two Swedish municipalities, the aim of this article is to explore how sport and culture are formed as means to promote social policy objectives regarding young people. In addition, we reflect on the political significance of this in relation to the development of local policy. The analysis demonstrates how a discourse of urban segregation and unequal opportunities underpins actions to mobilise non-participant and at-risk youth. This is achieved by establishing centres for sport and culture, and by enabling an educational approach which focuses on participation, empowerment and good citizenship. Reasons for mobilising practices involving culture and sport overlap, though each area of policy appears to be differently underpinned by discourses of enlightenment and conformity. Differences in emphasis between the discourses on sport and culture are discussed in relation to scientific discourse on the social utility of each policy area.     

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.     

Account of an Informed Bat Exclusion at the Temple of Deir el-Shelwit,Luxor, Egypt

Abstract

The conservation of the painted Roman-era reliefs in the temple of Deir el Shelwit in Luxor, Egypt, was recently initiated by the American Research Center in Egypt (ARCE). As a critical step in a series of preliminary preventive conservation measures undertaken at the temple, a resident bat colony was excluded to control further deterioration of the painted reliefs and stone fabric (Figure 1). In consultation with a bat biologist, a comprehensive humane, low-tech emergency exclusion programme was designed and implemented, which included roost location, behavioural surveys, species identification, sealing of building openings, bat exclusion and the design of an alternate roost site. This programme may serve as a useful example for other conservation projects in Luxor, since it provides much-needed information on the behaviour of local bats, as well as relevant insights gained from the exclusion procedure.     

Ethics,politics and practices in rock art conservation

Abstract

Weathering and deterioration of Norwegian rock art has become an increasing area of concern over the last decade, with subsequent increasing efforts towards conservation. This has brought questions onto the agenda regarding the ethics and politics involved in conservation theory and practice. It is argued that such issues have been difficult to debate due to the concept of conservation being regarded as a legal and moral ideal. Referring the situation in Norway to ongoing global debates and perspectives regarding rock art conservation enables us to reveal and discuss some of the fundamental and complex philosophical issues involved. Notions of authenticity which implicitly underlie attitudes to rock art conservation are questioned, and the relationship between ‘green’ politics and rock art conservation is also discussed. A tendency towards uniform solutions and avoidance of critical issues, seen as influenced by strong social-democratic political traditions in Scandinavia, is at odds with the growing realization that most approaches to rock art conservation inevitably have unforeseen and frequently undesired consequences. Rather than further segmenting ethics, politics or practices in rock art conservation, a self-critical and reflective approach is suggested whereby changing concepts of ethics and authenticity are continuously debated.

Aucune loi ne pourra jamais préserver la sacralité d'un lieu … si ce n'est une loi morale, non écrite,adoptée et respectée par chaque individu, un véritable code personnel d'éthique.

Post-colonial heritage conservation in Africa: perspectives from drystone wall restorations at Khami World Heritage site,Zimbabwe

Abstract

Before colonialism, heritage sites such as Khami were considered resting places for ancestors, valued more for the spirit of place than their monumentality. In this context, local custodians hardly intervened with the fabric of the site. With the introduction of modern conservation principles, which persist to this day, vegetation control and wall restorations became part of routine conservation measures. This paper discusses drystone wall restorations carried out at Khami between 2000 and 2015 focusing on the disjuncture between indigenous and local concepts of heritage, concerned with access and preserving the spirit of ancestors, and ‘western’ principles of restoration. It argues that while ignoring the structural disintegration of Khami would have resulted in possible delisting from the World Heritage List, the ‘neglect’ which Khami experienced was in tandem with its local social context; being a resting place for ancestors. While the reconstructions interfered with an acceptable physical context of local beliefs, restorations maintained the integrity of the site as a tourist destination with positive local economic benefits. Although compromises are by their nature unsatisfactory, modern heritage conservation in Africa must adapt and improvise to achieve a mix of local and international practices to reflect changed and changing realities.     

Assessment Techniques for Studying the Effects of Fire on Stone Materials: A Literature Review

ABSTRACT

Fire is one of the most severe threats to stone applied in civil engineering and architecture. In most cases, its effects are irreversible and have long-lasting repercussions. In addition to aesthetic alterations, fire can also induce important mineral-chemical, physical, and mechanical changes in stone. Research concerning the effects of fire on stone materials in recent decades has been providing valuable knowledge to inform present and future conservation and restoration actions. In this literature review, the properties and techniques used for studying the effects of fire on stone materials are appraised, summarized, and compiled. A comprehensive and practical overview of those effects is also given. Open porosity and P-wave ultrasonic velocity are the physical and mechanical properties that have been studied most. Other frequently researched areas include chemical-mineralogical changes, color, density, water absorption, uniaxial compressive strength, and modulus of elasticity are also very frequently investigated.     

Comparison of Original and Modern Mortars at the Herculaneum Archaeological Site

ABSTRACT

This paper aims to evaluate mineralogical, elemental, and thermal differences among original Roman joint mortars and those used in twentieth-century restoration campaigns taken from different areas at the Herculaneum archaeological site. The purpose is to improve the compatibility of restoration mortars. Roman and modern mortars were studied with petrography, thermal analysis and x-ray fluorescence investigations. The results indicate significant differences between the Roman and modern mortars which could facilitate the degradation process. Roman mortars, in particular, were composed of a coarser aggregate which was present in a lower ratio with binder in comparison with modern mortars.     

‘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 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.     

From verifiable authenticity to verisimilar interventions: Xintiandi,Fuxing SOHO,and the alternatives to built heritage conservation in Shanghai

ABSTRACT

The introduction of contemporary architecture into historic urban environments creates an open heritage discussion that includes the underlying relationship between development and conservation. This discussion requires theoretical clarification, as heritage conservation is frequently mistaken for other architectural design approaches that, even though they may operate within the historic environment as their primary source, do not comply with the complex definition of heritage authenticity used today. This article aimed to contribute to this debate, offering a characterization of such architectural design strategies operating through principles of verisimilitude that target authentication for tourists and the creative classes in a global city like Shanghai. Comparative studies of Xintiandi (Ben Woods, 2001) and Fuxing SOHO (Von Gerkan, Marg und Partner, 2015) provided an insight into the concepts of historic re-creation and abstract inheritance, currently used as ways of interpreting the historic residential typology of the Shanghai lilong according to the economic and political aims of the entrepreneurial model of governance. This allowed a critical evaluation of the growing attention paid to heritage in Shanghai in the last 25 years, and whether the substitution of the principle of authenticity for authentication has solved the contradictions between urban conservation and development in contemporary China.
