Should cultural relics and historic sites be renovated?

There are nine main methods and principles for the protection of historical and cultural heritage, such as cultural relics and historic sites:

Preservation intact (frozen preservation): preservation intact, keeping the authenticity of history and culture. This is the standard advocated by the United Nations. Generally, cultural relics should be preserved intact;

keep the old as it is-carefully repair: the damaged buildings (ancient relics) should be "kept as it is, so as to preserve their authenticity". The Venice Charter puts forward two principles of restoration recognized by all countries in the world: the repaired and filled-in parts must form a whole with the original parts, and maintain harmony and consistency in the landscape, which will help to restore but not reduce its artistic value, historical value, scientific value and information value;

The added part must be different from some parts, so that people can distinguish between historical and contemporary additions, so as to maintain the historicity of cultural relics. In addition, reinforcement and maintenance should be as little as possible, that is, the principle of necessity;

Carefully rebuild: Some very important historical buildings were destroyed for some reason. Because they are important local features and symbols, it is necessary to rebuild them if conditions permit. Reconstruction is memorable. However, reconstruction must be cautious and demonstrated by experts, because reconstruction will inevitably lose the authenticity of history, cost a lot of money and destroy the remains. It is more valuable to preserve the remains in more cases;

utilization is based on the premise of not damaging the heritage. The use of historical and cultural heritage is based on the premise of not damaging the heritage, and it is best to continue the original use method. It can also be used as a museum and a tourist attraction to be cautious to prevent damage;

maintain the pattern characteristics of historical blocks and ancient cities. Focus on protecting the plane layout, azimuth axis, road skeleton, river network and water system of historical blocks and ancient cities;

protection of characteristic architectural style: protection of characteristic architectural style, including architectural style, height, volume, material, color, plane layout and relationship with surrounding buildings. It is very important to control the appropriate building scale-height and volume, bearing in mind that the present and the present are different, and it is not required to be high and large;

protect the historical environment: things are inseparable from their existing environment and cannot exist without the environment. The significance of the historical and cultural heritage environment is more important, and the important, characteristic and important history-related topography, landforms, Yuan Ye, water bodies, flowers and trees and their characteristics should be protected;

old towns, villages, streets and ancient buildings that are not sure should not be demolished for the time being. Many remote places, especially mountainous rural areas, ancient towns, ancient villages, ancient streets and ancient buildings, although not key cultural relics protection units, are also historical and cultural heritage with considerable value. The local people don't know if they have the financial resources and opportunities to invite experts to identify them. In this case, it is best not to dismantle it temporarily, so as not to cause regret, and it will be handled according to the situation after being demonstrated by experts.

do a good job in the protection planning of historical and cultural ancient cities and historical and cultural areas. Planning is the leading factor, and protection must be based on planning, which must go ahead. With a plan, protect it according to the plan.
