Principles of repair and protection of historical buildings

In 1961, the State Council of the People's Republic of China published "Interim Regulations on the Protection and Management of Cultural Relics", which clearly stipulates that in the ancient buildings and historical monumental buildings, grotto temples, etc. (including the appurtenances of the buildings) for repair, maintenance, "must abide by the principle of restoration of the original state or the preservation of the status quo." 1982 The Chinese People's **** and the State Law on the Protection of Cultural Relics published in 1982 stipulates that "revolutionary sites, memorial buildings, ancient buildings, ancient tombs, grotto temples, stone carvings, etc. (including the appurtenances of the buildings) approved as units of cultural relics protection, in the course of repair, maintenance, relocation, must comply with the principle of not altering the original state of the cultural relics."

Repair of the core

The original state refers to the appearance of an ancient building when it began to be constructed (subject to the era of the existing main structure ), or the existing healthy appearance after repair by future generations. The original state of the whole group of buildings, should include its original general layout, spatial combination and its internal environment of the green. Generally speaking, it refers to the original shape, the original structure, the original material and the original technology. These four elements are indispensable.

Restoration of the original state: refers to the maintenance of ancient buildings, will be changed in history and has been crippled part of the conditions in a sufficient scientific basis to be restored, reproducing the ancient buildings in the history of the real face. Restoration of the original state must be based on the age of the existing main structure of the ancient buildings. However, the restoration of altered and mutilated parts, generally limited to the structural part of the building, for statues, murals, carvings and other works of art, generally should be preserved as is.

Preservation of the status quo: the maintenance of ancient buildings, should be based on the existing appearance, retaining the repair of successive generations of the altered parts, preserving the historical legibility of ancient buildings. Practice has proved that the status quo and the original state often some intrinsic connection, the status quo is the study of the original state of the indispensable reference material.

International Conference in 1964 adopted the "Venice Charter", is a lot of countries *** with the observance of the protection and maintenance of cultural relics regulations. The charter first emphasizes the protection and restoration of ancient buildings, both as historical witnesses, but also as works of art to protect. For the restoration work, should be regarded as a highly specialized technology, must respect the original information and conclusive documentation, there can not be the slightest speculation. Any unavoidable additions must be clearly differentiated from the original architectural appearance. When the traditional technology can not solve the problem, can quote the new technology, but must be proved effective by experiment.
