Monument preservation

from Wikipedia, the free encyclopedia
Monument maintenance on the Propylaea of ​​the Acropolis (Athens)

The intellectual, technical, technical and artistic measures that are necessary for the preservation and maintenance of cultural monuments are referred to as monument preservation . Monument protection, on the other hand, encompasses the legal orders, orders, permits, conditions or prohibitions that ensure the preservation of monuments.


The central task is to take stock, view and catalog monuments as evidence of past cultural history , i.e. both protected and protected objects. The monument authorities keep quick entry lists, monument lists or monument registers for this purpose . In addition, there are some monument topographies .

Architectural monuments, ensembles, archaeological sites and parks with which people designed and reflected their environment are part of the cultural heritage of society. Just like artistic creations, inventions and scientific discoveries, monuments are objects of collective memory. It is through them in particular that the political, social and economic developments of the past become clear and can be directly experienced in our living environment. The expressiveness of the monument is linked to its material substance. The buildings to be preserved in their traditional state, together with the historical traces of use and changes, is therefore the first objective of architectural conservation. As historical legacies of human activity, monuments play an identity-creating role in society. The preservation of monuments is dedicated to the task of preserving this legacy of building, soil and garden monuments passed on to the community for future generations and protecting it from damage or destruction. An important prerequisite for the preservation of architectural monuments is that they are used continuously. If a building stands empty for a long time, damage occurs and it is difficult to bring the building back into use. The preservation of monuments advocates such uses and any necessary contemporary structural additions that can be achieved without impairing the historical substance.

From an international perspective, UNESCO and its partner organization Blue Shield are concerned with the definition, inventory, protection and restoration of monuments as evidence of past cultural history. This also applies to military conflicts. For example, "no-strike lists" are created with the support of local experts. It is not enough just to develop international legal norms such as the Second Protocol to the Hague Convention for the Protection of Cultural Property in the Event of Armed Conflict or the Doha Statement of the “Conference of 'Ulamâ on Islam and Cultural Heritage”. It is necessary to implement and implement these standards effectively globally. It can also be important, despite the partial dissolution of state structures and the very unclear security situation as a result of the wars and unrest, to carry out robust undertakings to protect the monuments and cultural assets.

History of the preservation of monuments

Face of the 5 DM commemorative coin European Monument Protection Year

The first country in which a central state authority was established for the preservation of monuments was Sweden . In the founding decree for the Reichsantiquariatsamt of 1630, King Gustav II Adolf decreed that the antiquarians should “ look for and collect all sorts of old monuments and objects that can be used to illustrate the fatherland, primarily all old runic inscriptions [...] both in books and on stones, broken and whole, and note how they are made, carefully research how many there are in each parish, also write down the legends of each stone [...] ”. The first Swedish imperial antiquarian, Johannes Bureus , did not limit himself to recording the runes, but expanded his commission to include historical churches, castle walls and tombs. In 1662 a " decree on old monuments and antiques in the empire " was posted publicly. It is considered to be the first monument protection law in Sweden and perhaps Europe. In 1662, a professorship for antiquities was established at Uppsala University . From 1667 the scientific inventory of cultural monuments began, which was also published. Sweden was at the forefront of monument conservation in Europe.

In 1798 Ferdinand Franz Wallraf became Conservateur des monumens in Cologne under French law , an office that the sub-prefect's circular of April 25, 1807 extended to the protection of monuments in the then Cologne district .

In the German Empire , the first modern monument protection law in Germany was passed in 1902 with the law on monument protection in the Grand Duchy of Hesse .

The Athens Charter in 1931 dealt with the basic principles of the restoration and display of architectural monuments. The Venice Charter of 1964 was a milestone in the development of monument preservation .

The "European Architectural Heritage Year" 1975 (officially: European Architectural Heritage Year (EAHY)) is simply the beginning of the socially anchored awareness of monument preservation. Ensemble protection in particular was promoted. In the 1970s, many countries introduced new monument protection laws. In the same year, a monument preservation law was also passed in the GDR. (see monument protection in the GDR )

Since the 1990s, economization seems to have found its way into the preservation of monuments and thus possibly a paradigm shift. This is reflected, among other things, in public opinion and especially in politics. The qualitative discussion of the archaeological and architectural heritage is hardly of any importance.

Preservation of monuments assesses the condition of cultural monuments and decides on any measures to be taken to maintain or maintain them. As a rule, the relevant scientific and technical competence and the financial support are concentrated in the responsible monument authority . The legal framework conditions are the monument protection laws of the federal states. For each cultural monument , it must be decided individually how it can be preserved in the long term. The main procedures are set out in the Venice Charter . However, there is a wide scope for interpretation. The monument conservator and architect Hermann Wirth from the Bauhaus University Weimar says: "The term redevelopment, which is also used in this context, usually has nothing to do with monument conservation."

Renovation is not a monument-specific term and is not mentioned in any of the monument protection laws. Refurbishment does not mean a specific measure. The term has undergone a fundamental change and today generally stands for modernization that goes beyond the preservation of historical monuments.

The main measures of monument preservation are:

Let old age

No or only very little intervention. A common concept around 1800 and 1900, especially for castle ruins, currently mainly used in large industrial plants as controlled decay .


Cleaning and maintenance work on the monument. This includes fastening bricks, grouting, painting windows, etc. This care concept gave the monument preservation its name.


Preservation and securing of the historical and material inventory. The aim of conservation is to preserve the original condition and appearance at the time of the measure and is achieved through cleaning, care or careful consolidation of the historical material (see for example stone conservation ). Another possibility to achieve the conservation of cultural monuments is to protect ground monuments or architectural monuments from decay by means of protective structures. One example of this is the protective structure above the golden gate of Freiberg Cathedral in Saxony.


Measures that serve to secure and maintain the original substance and to restore its original condition and practical value or to renew an original appearance:

Restoration of the original usability while preserving the original substance. The return to an "original state" is not the aim of a restoration.
Restoration of a previously existing appearance, based on the original findings.


Reconstruction of the 19th century: The ancient Athenian Panathinaiko Stadium was the 1896 Summer Olympics rebuilt

Recovering a lost appearance of components or entire buildings, sometimes without original findings, on the basis of written and pictorial sources and results of building research. Reconstructed objects are considered new creations and represent an absolutely exceptional situation for the preservation of monuments. They are often no longer cultural monuments (depending on the entry status in the monument lists), but over time they can gain a monument value . In the parlance of the GDR under reconstruction the repair or modernization (regardless of the monument value) was understood.


Anastilosis describes the partial reconstruction of a dilapidated historical building using its original, preserved components. A well-known example is the Celsus library in Ephesus .

Relocation - building relocation

Relocation is a building relocation process. During the relocation, the building will be documented, dismantled and then rebuilt in a different location as true to the original as possible. This reconstruction at another point is often an emergency measure in the event of impending total loss. Since a cultural monument derives its monument value to a certain extent from the - also local - historical context in which it was created, the relocated object can lose its official monument protection ; As a rule, it does not lose its monument status as a testimony to a bygone culture .

In some countries, the maintenance of some selected cultural monuments - mostly in public ownership - is the responsibility of the monument authority. This can include long-term planning to restore an approximate historical inventory.

Preservation of monuments usually burdens the owner of the monument and can lead to significant financial obligations. In Germany, for example, the special burden on the monument owner is based on Article 14, Paragraph 2, Clause 2 of the Basic Law, the social commitment of property. This is a restriction on his property.

Soil monument maintenance

Excavation in the Xanten Archaeological Park (2005)

The Bodendenkmalpflege deals with archaeological monuments , so immovable or movable monuments that are located in the ground or were, d. i.e. it is the task of special authorities . The preservation of monuments is divided into archaeological preservation and paleontological preservation .

The tasks of the preservation of monuments range from the systematic inventory and inventory (by means of inspections, aerial photo interpretation, building survey , etc.), review of planned construction measures for relevance to the preservation of historical monuments , preliminary investigation ( prospection ), excavations (planned or as emergency excavation in case of destruction by construction measures), restoration and cataloging of salvaged Objects, the scientific processing and publication of the results found up to their presentation.

Building and art monument maintenance

The building and art monument maintenance is based on art history and architectural studies. It occupies a very large area within the preservation of monuments.

The architect Karl Friedrich Schinkel demanded protection authorities for art monuments in the early 19th century. In France , Viollet-le-Duc is considered to be the founder of the stylistic restoration that began around 1830. In Prussia there was the first curator, also known as the monument conservator , in 1843 . In 1850 the Austrian Kk Central Commission for the research and preservation of architectural monuments was founded. It was subordinate to the Ministry of Trade and Industry.

Baron Charles de Graimberg (1774–1864 / 65?), The “savior” of Heidelberg Castle , is considered to be the first officially commissioned curator, at least in Germany. Thanks to his image publications, further state efforts began in Baden to protect the ruins from further overexploitation.

In 1911, the Central Commission for Research and Conservation of Architectural Monuments in Prussia was converted into the State Monuments Office . This was divided into two areas: an art-historical-technical area, which dealt with the preservation of monuments and a legal-administrative area, which was responsible for the legal basis.

Garden monument maintenance

The garden monuments has been established as a separate field of historic preservation for only a few decades. Legally, like landscape architecture, it is counted as part of the preservation of historical monuments.

Urban preservation of monuments

Monument and controversial new building in Fürth .

The monument or the monument ensemble is in a spatial context. The urban development should be considerate of monuments and their surroundings, not to impair its value and effect. This is why cities with large historical buildings have often developed statutes and plans to protect the silhouette, roof and facade design. This can also include the preservation of historical squares and streets. The definition of the course of the building fronts also secures the historical street spaces. One of the instruments for the historical analysis of the city plan is city ​​morphology . In the case of particularly important historical buildings and ensembles, protection zones are required that limit and regulate building in the area. So has z. For example, UNESCO has demanded protection zones for the Cologne Cathedral World Heritage Site from the city of Cologne , or Dresden revokes its status due to certain construction activities.

Urban monument protection serves to protect historical city centers. Through the urban monument protection program , areas in Germany are funded by the federal and state governments in order to bring about the unity between building and urban renovation in selected cities with particularly significant city centers.

Historical building research

The building research is the study of architectural history and the substance of a building. In addition, it provides data for documentation that is independent of the substance. Its goals are to assess the historical value and to gain knowledge for appropriate measures of monument preservation, also in the case of renovation.

Building research is a step-by-step approach, usually starting with a true-to-scale, usually accurate deformation drawing, the so-called building survey . This provides knowledge about the morphology of the building and conservation problems. Another step is the room book , a graphic, photographic and descriptive documentation of the building and its parts. It is important to have a systematic structure that no longer deviates from a level of precision that has once been defined - or is enforced over time, i.e. no longer selects subjectively. Together with the evaluation of archive materials, building research achieves a precise knowledge of the historical value of a building, which is used for upcoming measures and for the pure documentation of data in the archive.

Current situation of the preservation of monuments

Conflict case: modern building law and historical building fabric

The monument authorities in Germany are currently reaching the limits of their ability to act and resilience due to the financially tense financial situation and their staffing levels. Numerous specialist authorities have lost their academic autonomy and their associated independent position in recent years, and some specialist offices have been dissolved. The more civic engagement is required and promoted.

26 resolutions of the Council of Europe deal with various aspects of monument preservation. Implementing the resolutions is proving difficult. Work is currently underway on a common European platform, as the cross-border professional cooperation still leaves a lot to be desired. In April 2006 a European Heritage Heads Forum (EHHF for short) was set up in London at the invitation of English Heritage by heads of monument offices from 23 European countries . It is supposed to meet annually as a common lobby to exchange ideas, organize joint workshops and actions and strengthen and expand existing networks between monument preservation and tourism.

Promotion of the monument preservation idea

Open Monument Day 2005 in Berlin: Guided tour through the mezzanine level of the Moritzplatz underground station

The European Heritage Days introduced by the European Union are held every September in order to anchor the cultural significance of monuments in the sense of “living history” in the minds of the citizens. There is a different topic every year.

In Germany this event is called Day of the Open Monument , in Austria Day of the Monument . Switzerland is also participating in this campaign with the European Heritage Day .

At the European level there is also a cross-national association with Europa Nostra for the dissemination of the monument protection idea, which organizes the “ European Union Prize for Cultural Heritage / Europa Nostra Awards ” and thus awards the highest distinction for monument protection at European level.


“Every monument is tied to the material substance of which it is made and which makes its existence possible in the first place. It allows us to understand the process of creation and processing of the monument, but also shows the traces of time that has passed since its completion, reports on conversions, changes and functional changes, the fate of the residents and users, and good and bad phases. "

- Achim Hubel : Monument Preservation - Tasks, Goals and Problems of Current Monument Preservation, p. 311 , Stuttgart 2006/2011

Training, research and teaching in German-speaking countries

Preservation of monuments is the subject of various trades, such as stonemasons and especially in Bavaria the so-called church painters . The profession of restorer is not protected in all federal states, meanwhile an independent chair has been set up in Munich. The profession of self-employed window craftsman specializes in monument- compliant window repairs and only came to Germany from Sweden in the late 1990s. This still young job description is not legally protected in Germany and is passed on from window craftsmen to self-employed craftsmen in related professions. A number of interdisciplinary postgraduate courses have been set up specifically for monument preservation, for example in Bamberg, Hildesheim and Potsdam. The courses in Munich and Dresden have since been abandoned.

Training centers:

The preservation of monuments has the status of a minor subject in the German university landscape . According to the Small Subjects Department, there are (as of June 2019) nine independent chairs for monument preservation at eight German universities. In 1997 there were still seven professorships at seven locations.
