Architectural heritage

Last updated

Architectural heritage is a form of tangible and immovable cultural heritage centered around the documentation and preservation of the built environment of existing and past buildings and structures built for residential, commercial, industrial, defensive, governmental, and spiritual purposes. [1] These buildings and structures can vary widely in size, sophistication, and design based upon the resources and materials available at the time of construction and the cultural understanding of historical precedents and collective memory of architectural styles known to the architects and builders at the time of design and construction. [2]

These historic buildings and archaeological sites can illustrate the spatial arrangements and sociocultural interactions influenced by the built environments of historic times, and can vary in importance based upon the cultural significance or physical rarity of a particular type of architectural structure. [3] Additionally, the historic and prehistoric interactions between humans, the environment, land and sea usage, and interaction with other cultures can play a significant role in the development of stages of civilization and human history, including traditions, ideas, beliefs, and artistic and literary works that can display human creative genius and outstanding universal significance. [4]

Study of architectural heritage sites

Architectural heritage can be studied by architects, architectural historians, cultural historians, archaeologists, anthropologists, and a variety of other disciplines through such methods as surveys, delineations, measurements, drawings, and renderings to depict existing structures of historical significance or heritage value, study and conservation of past drawings, blueprints, and renderings of existing and past buildings, and geospatial surveys and scans of historic or archaeological sites, including satellite images, photogrammetry, LIDAR scans, and SONAR renderings of underwater submerged archaeological sites. [5] Surveys, delineations, drawings, and renderings, when properly conserved as part of the documentary heritage of the architectural tradition, can be digitized to help ensure their conservation and communication in the event of the original copy or the extant structure being destroyed. [6]

Geospatial surveys and scans can also help researchers see evidence of historic or prehistoric structures that might not be visible to the naked eye, for example if only foundations of the structures remain underground, if geological shifts or volcanic eruptions have caused the buildings to become buried under sedimentation or ash deposits, if once land based archaeological sites have become buried underwater due to rising sea levels or geological shifts, or in the event the site is simply too inaccessible to be physically accessed by researchers due to excessive vegetation cover or rough and jagged terrain. [7] These delineations, surveys, and scans can help researchers understand the types of buildings and structures historic and prehistoric people built, as well as what they show about how people interacted with each other and their environment. [8]

Human and natural threats to architectural heritage sites

Architectural heritage sites can be threatened by a number of human and natural threats, such as armed conflicts, lack of preservation or conservation measures, demolition or excessive modification, exposure to environmental elements, and natural disasters such as hurricanes, typhoons, tornadoes, floods, earthquakes, and excessive winds. [9] [10] Additionally, excessive tourism can also pose a threat to the integrity of the historic sites if poorly managed or insufficient preventative conservation measures are in place. [11]

Architectural conservation and historic preservation

Ongoing assessments and monitoring of architectural heritage sites help maintenance and restoration personnel identify architectural elements that are in a stable state of conservation and which elements are in need of treatments and restorations. [12] These ongoing assessments might include wood treatments, historic paint analyses, pest and rodent control, and monitoring of temperature and relative humidity. [13]

Architectural preservation treatments can run from smaller scale restorations to major reconstructions. [14] Smaller scale restorations might include repainting and refinishing surfaces, environmental barriers, water gilding, sandblasting fixtures, and repairing utility connections, such as electrical wires and plumbing pipes. [15] Larger scale restorations and reconstructions might seek to demolish architectural elements or portions of buildings in the interest of restoring the overall structure to an earlier state which better represents a period in history which the architectural significance of the building is better associated with. [16] [17]

Similar to any form of tangible cultural property, architects, restorers, historic site and museum professionals always recommend involving a conservator before undertaking any major restoration projects on a site with architectural heritage significance. [18] Additionally, many restoration projects require the involvement of a structural engineer to determine if the proposed modifications and treatments might negatively impact the structural integrity of the building or surrounding elements, or if additional building permits and inspections might be necessary before undertaking the work. [19]

At the international level, the United Nations Educational, Scientific, and Cultural Organization administers the World Heritage Program to identify locations whose architectural or natural heritage, or some combination thereof, have outstanding universal value measured against a set of ten criteria, including representation of masterpieces of human creative genius, exhibiting important interchanges of human values, bearing a unique or at least exceptional testimony to a cultural tradition or civilization which is living or has disappeared, and being an outstanding example of a type of building, architectural, or technical ensemble or landscape which illustrates a significant stage in human history. [20] Locations inscribed on the World Heritage List can be eligible to receive funds from the World Heritage Fund to help protect the architectural heritage sites, which is funded from voluntary and involuntary contributions from the state parties to the World Heritage Convention. [21]

Most nations have a mechanism to identify historic buildings and heritage sites of national or regional significance which should be protected from unauthorized demolition or alteration, such as the United States Department of the Interior's National Register of Historic Places. [22] Additionally, some nations, such as the United Kingdom, further assign historic structures into categories based upon their historical and architectural significance, such as Historic England's grading of listed buildings. [23] These grades and categories can help governments, planning and zoning organizations, grant distributors, historical societies, and property managers obtain the resources necessary to maintain and conserve buildings and structures of outstanding universal value, while allowing for some flexibility for modification and use of sites of lower historical significance.

In the broadest sense, cultural resource management (CRM) is the vocation and practice of managing heritage assets, and other cultural resources such as contemporary art. It incorporates Cultural Heritage Management which is concerned with traditional and historic culture. It also delves into the material culture of archaeology. Cultural resource management encompasses current culture, including progressive and innovative culture, such as urban culture, rather than simply preserving and presenting traditional forms of culture.

The International Council on Monuments and Sites is a professional association that works for the conservation and protection of cultural heritage places around the world. Now headquartered in Charenton-le-Pont, France, ICOMOS was founded in 1965 in Warsaw as a result of the Venice Charter of 1964 and offers advice to UNESCO on World Heritage Sites.

<span class="mw-page-title-main">Historic preservation</span> Preservation of items of historical significance

Historic preservation (US), built heritage preservation or built heritage conservation (UK) is an endeavor that seeks to preserve, conserve and protect buildings, objects, landscapes or other artifacts of historical significance. It is a philosophical concept that became popular in the twentieth century, which maintains that cities as products of centuries' development should be obligated to protect their patrimonial legacy. The term refers specifically to the preservation of the built environment, and not to preservation of, for example, primeval forests or wilderness.

Conservation and restoration of immovable cultural property describes the process through which the material, historical, and design integrity of any immovable cultural property are prolonged through carefully planned interventions. The individual engaged in this pursuit is known as an architectural conservator-restorer. Decisions of when and how to engage in an intervention are critical to the ultimate conservation-restoration of cultural heritage. Ultimately, the decision is value based: a combination of artistic, contextual, and informational values is normally considered. In some cases, a decision to not intervene may be the most appropriate choice.

The Venice Charter for the Conservation and Restoration of Monuments and Sites is a set of guidelines, drawn up in 1964 by a group of conservation professionals in Venice, that provides an international framework for the conservation and restoration of historic buildings. However, the document is now seen by some as outdated, representing Modernist views opposed to reconstruction. Reconstruction is now cautiously accepted by UNESCO in exceptional circumstances if it seeks to reflect a pattern of use or cultural practice that sustains cultural value, and is based on complete documentation without reliance on conjecture. The change in attitude can be marked by the reconstruction in 2015 of the Sufi mausoleums at the Timbuktu World Heritage Site in Mali after their destruction in 2012.

In conservation, library and archival science, preservation is a set of preventive conservation activities aimed at prolonging the life of a record, book, or object while making as few changes as possible. Preservation activities vary widely and may include monitoring the condition of items, maintaining the temperature and humidity in collection storage areas, writing a plan in case of emergencies, digitizing items, writing relevant metadata, and increasing accessibility. Preservation, in this definition, is practiced in a library or an archive by a conservator, librarian, archivist, or other professional when they perceive a collection or record is in need of maintenance.

<span class="mw-page-title-main">Conservation science (cultural property)</span> Interdisciplinary study

With respect to cultural property, conservation science is the interdisciplinary study of the conservation of art, architecture, technical art history and other cultural works through the use of scientific inquiry. General areas of research include the technology and structure of artistic and historic works. In other words, the materials and techniques from which cultural, artistic and historic objects are made. There are three broad categories of conservation science with respect to cultural heritage: understanding the materials and techniques used by artists, study of the causes of deterioration, and improving techniques and materials for examination and treatment. Conservation science includes aspects of materials science, chemistry, physics, biology, and engineering, as well as art history and anthropology. Institutions such as the Getty Conservation Institute specialize in publishing and disseminating information relating to both tools used for and outcomes of conservation science research, as well as recent discoveries in the field.

<span class="mw-page-title-main">Conservator-restorer</span> Professional responsible for the preservation of artistic and cultural artifacts

A conservator-restorer is a professional responsible for the preservation of artistic and cultural artifacts, also known as cultural heritage. Conservators possess the expertise to preserve cultural heritage in a way that retains the integrity of the object, building or site, including its historical significance, context and aesthetic or visual aspects. This kind of preservation is done by analyzing and assessing the condition of cultural property, understanding processes and evidence of deterioration, planning collections care or site management strategies that prevent damage, carrying out conservation treatments, and conducting research. A conservator's job is to ensure that the objects in a museum's collection are kept in the best possible condition, as well as to serve the museum's mission to bring art before the public.

<span class="mw-page-title-main">Inpainting</span> Image conservation process

Inpainting is a conservation process where damaged, deteriorated, or missing parts of an artwork are filled in to present a complete image. This process is commonly used in image restoration. It can be applied to both physical and digital art mediums such as oil or acrylic paintings, chemical photographic prints, sculptures, or digital images and video.

Historic paint analysis, or architectural paint research, is the scientific analysis of a broad range of architectural finishes, and is primarily used to determine the color and behavior of surface finishes at any given point in time. This helps us to understand the building's structural history and how its appearance has changed over time.

<span class="mw-page-title-main">Conservation and restoration of archaeological sites</span> Process in archaeology

The conservation and restoration of archaeological sites is the collaborative effort between archaeologists, conservators, and visitors to preserve an archaeological site, and if deemed appropriate, to restore it to its previous state. Considerations about aesthetic, historic, scientific, religious, symbolic, educational, economic, and ecological values all need to be assessed prior to deciding the methods of conservation or needs for restoration. The process of archaeology is essentially destructive, as excavation permanently changes the nature and context of the site and the associated information. Therefore, archaeologists and conservators have an ethical responsibility to care for and conserve the sites they put at risk.

Digital heritage is the use of digital media in the service of understanding and preserving cultural or natural heritage.

The conservation and restoration of Pompeian frescoes describes the activities, methods, and techniques that have historically been and are currently being used to care for the preserved remains of the frescoes from the archeological site of Pompeii, Italy. The ancient city of Pompeii is famously known for its demise in A.D. 79 after the fatal eruption of Mount Vesuvius wiped out the population and buried the city beneath layers of compact lava material. In 1738, King Charles III or Charles of Bourbon, began explorations in Portici, Resina, Castellammare di Stabia, a Civita, where it was believed that the ancient cities of Pompeii, Stabiae, and Herculaneum were buried beneath. The first phase of the excavations at Pompeii started in 1748, which led to the first conservation and restoration efforts of the frescoes since their burial, and in 1764, open-air excavations began at Pompeii. Pompeii has a long history of excavation and restoration that began without a strong foundation or strategy. After centuries of cronyism, recurring financial shortages, and on-again-off-again restoration, the city's frescoes and structures were left in poor condition. In 1997, Pompeii was added to the UNESCO List of World Heritage Sites.
