THE CONSERVATOR’S RESPONSIBILITY FOR THE DETERIORATION OF MONUMENTS

Over the last decades, built heritage and the conditions of its protection have changed a lot. There has been a significant increase in the number and diversity of monuments. The expectations of contemporary societies regarding the use of heritage have changed as well. As a consequence, the ownership, protection, financing and use of heritage has been privatized. These conditions should be reflected in conservation theory. Conservation theory should be realistic it should indicate how to protect and use heritage in practice. Therefore, it is necessary to scientifically develop a modern conservation theory. The application of conservation theory which does not take into account contemporary conditions contributes to chaos in the protection of monuments and facilitates the destruction of their values. Therefore, the development of contemporary conservation theory can also be considered an ethical problem.

There has been a significant increase in the number and diversity of monuments. The expectations of contemporary societies regarding the use of heritage have changed as well. As a consequence, the ownership, protection, financing and use of heritage has been privatized. These conditions should be reflected in conservation theory. Conservation theory should be realistic -it should indicate how to protect and use heritage in practice. Therefore, it is necessary to scientifically develop a modern conservation theory. The application of conservation theory which does not take into account contemporary conditions contributes to chaos in the protection of monuments and facilitates the destruction of their values. Therefore, the development of contemporary conservation theory can also be considered an ethical problem.

KEYWORDS: Paradigm shift, heritage protection, conservation theory
Modern heritage protection is a complex and difficult task. Many historical sites are being destroyed and this worrying issue draws particular attention. However, at the same time, the limits of conservation interventions into historical sites are being pushed further and further. In many cases it is even hard to tell if the undertaken actions still belong to heritage protection 1 . There are many examples of such activities all over the world.
The numerous examples show that objects recognized as heritage and protected accordingly may lose their historical value and context. Therefore, critical analysis of the quality of modern heritage protection is necessary 2 . It is a very important ethical aspect of heritage protection in the twentyfirst century. This should become a topic of a debate among the conservation community. It is the responsibility of the International Scientific Committee Theory of Conservation and Restoration to elaborate this matter. The background to the debate on the quality of modern heritage protection should be the analysis of the conditions on which it is based 3 . Heritage protection is in principle not a discipline that defines the target, objective and methods of the action independently/autonomously. Heritage protection is a discipline determined and shaped by multiple external factors -technical, social, cultural, historical, political, financial, functional etc. However, for the purposes of this analysis three main aspects may be presented: -characteristics of contemporary heritage /object of interest/ -competences of conservators /heritage protection system/ -theory of conservation/ tools for analysis/ 2 A good example of activities shaping and popularizing the right forms of monument protection is the "Well-preserved Monument" campaign in Poland. This is a nationwide competition organized by the National Heritage Board, which supports and promotes appropriate forms of protection of various typological groups of monuments.

Characteristics of contemporary heritage
The first factor influencing contemporary heritage protection is the material characteristics of the set of elements that are recognized as heritage. Heritage is a vast and heterogeneous set of elements in bad condition that need significant intervention in order to perform contemporary functions. Each of these aspects have its own objective character. The problem can be illustrated by the example of listed heritage in Poland. This analysis concerns three aspects of the collection of historical objects in Poland. The first aspect is the quantity of monuments 4 . According to the National Heritage Board of Poland the set of monuments' documentation is the following 5 . (see Fig. 4) 4 Increasing the collection of objects considered as heritage is a common process. In England, for example, the number of listed buildings increased from the 1960s to the 1990s from around 100,000 to around 500,000. This means that there is 1 listed building per 100 people. The Polish version of the report contains different nomenclature than that, used in the tables (Figs. 5-8). However, the scale of evaluations reflects the meaning of the evaluation. In general, the results can be summarized as follows -only circa 10 % of historical objects do not require maintenance and renovation work. This means that for 90% of registered monuments, maintenance and revitalization work are required due to the poor technical condition of the historical object/form/ substance. The third aspect are the needs resulting from the adaptation of monuments to contemporary functions. Obviously, historical buildings need to be adapted to contemporary functions and it is a condition for their protection and funding. It is hard to find a simple indicator that would define all the needs resulting from the adaptation of historical buildings to contemporary functions and standards. However, the age of the building may be used as a simplified indicator. The older the building, the more it differs from modern standards of usability, technology and functionality. Therefore, the older the building, the more maintenance and renovation work is needed in order to adapt it to contemporary functions.
All the monuments listed in the Polish Heritage Register were divided according to the time period they were built in. Only 20% of the objects listed in the Heritage Register are from the twentieth century. In practice, however, they are a hundred years old. However, over 80% of objects are older. That is why, excluding the sacral architecture, the scope of intervention needed to adapt the great part of the historical sites to modern functions has to be huge. The statistics presented above give an overview of Polish Heritage and allow the following conclusion to be drawn. The objective conditions -amount of monuments, technical condition, functional requirements, etc. -mean that contemporary interventions (maintenance, revitalization and adaptation) need to be multidimensional and extensive. The maintenance of the proper technical condition as well as the adaptation of historical sites to modern standards and functions requires significant interventions and transformations of historical form and substance of the monuments. Furthermore, it causes a major decrease or even deterioration of the historical value. However, this process is necessary even if conducted in accordance with the guidelines and under the supervision of the conservator. Therefore, the work of the conservator will never be perfect and he/she will never be fully satisfied with its final result. He/she should always search for better solutions.

Competences of the conservator and stakeholders' participation
Characteristic of the contemporary protection system is the second main area/factor influencing the quality of heritage protection. The system of cultural heritage protection comprises many elements. One of the key factors defining these elements is the contemporary vision of the function of heritage and the responsibility for its protection. Obviously, these two elements are closely interlinked -they both derive from a certain philosophy of the perception of heritage. Heritage protection has undergone a change in recent decades as far as its paradigm is concerned 8 . It consists of changing the status of the heritage. The previous (traditional) paradigm could be compared to the contemporary (modern) paradigm in a few important aspects 9 . The characterized transfer of heritage to the present has very significant consequences as far as the construction of its protection system is concerned. Heritage stops being sacrum and starts being profanum. In consequence, it also leads to the privatization of ownership, protection, founding and responsibility for monuments. In this system the conservators cannot decide on the methods and forms of heritage protection as they do not have the appropriate instruments to force their concept of protection and usage of historical site. They are only one of the stakeholders and have to adapt to other, stronger ones -e.g. owners, investors, users. As a consequence, the conservator-restorer is a specialist organizing the dialogue among the stakeholders on possible actions to be applied on the historical object, not the protection itself. The change of the paradigm of monument protection has been presented in a collective publication -Conservation Turn -Return to Consevation. Tolerance for Change, Limits of Change, Edizioni Palistampa, Firenze, 2012.

Modern conservation theory / analysis tools/
In the past, when the set of monuments was relatively small and homogenous, the conservation theory was of a universal nature, such as the one formulated in the Venice Charter. Nowadays, the multitude and diversity of heritage objects and the conditions of their protection mean that the conservation theory does not have a universal nature.
There is no one theory that would be applicable to all typological groups of monuments. Therefore, modern conservation theory had to be divided. Certain typological groups of heritage as well as certain regions (conditions of protection) determine their own limits and forms of heritage protection.
Therefore, conservation theory is being laid out in dozens of doctrinal documents. Unfortunately, it cannot be treated as normative guidelines. A common characteristic for modern conservation theory is the admission of interference and transformation of the historical substance and form of the object. Regrettably, no analysis tools have been developed that would define the limits and possible consequences of these actions. Therefore, the interventions are also allowed in the case of World Heritage sites 10 . This main weakness of conservation theory combined with the weak conservator's position as far as specifying the forms of heritage protection result in the significant damage of historical objects and the deterioration of their historical values. What are the conclusions resulting from the presented situation and who they are addressed to? What can be done in particular areas?
The first task -it is necessary to formally distinguish/differentiate the status and the value of historic objects/monuments which belong to the very broad set of heritage. It will allow the rules and form of protection for different heritage groups to be defined. The second task -it is necessary to strengthen the position of conservator as far as the decisions regarding forms of heritage protection are concerned. The conservator has to have a privileged position among the other stakeholders -today the situation is the opposite. The third task -it is necessary to develop a methodology of analysis of historical objects that would define the attributes of historic values. It is necessary to elaborate the analytic tools in order to relate the heritage values to their tangible representation. The task formulated above belong to the area of conservation theory. It means that these are tasks for the International Scientific Committee on Theory of Conservation. Modern conservation theory should create the basis for heritage protection in the twenty-first century. It is also the precondition to emerge from the current crisis our discipline is in. 10 The necessity of combining the protection of World Heritage properties with their use (and necessary interventions) requires appropriate management -Managing Cultural World Heritage, World Heritage Center, 2013.
