World Heritage is required to be immovable heritages, such as monuments, groups of buildings, and sites, which are defined in the article 1 of the Convention. Movable heritages or immovable heritages that are likely to become movable are excluded.
World heritage needs to be placed under sufficient legal protection and securely protected by the country where it is located. [It needs to be designated by the domestic law (the Law for Protection of Cultural Properties).]
World heritage needs to meet one or more of the criteria for the assessment of outstanding universal value, which specified in the Operational Guidelines for the Implementation of the World Heritage Convention drawn by the UNESCO World Heritage Committee.
* There are other four criteria (vii, viii, ix, x) as the criteria for the assessment of natural heritage.
World heritage must conform to authenticity. That means the materials and cultural characteristics must be authentic. The restoration is acceptable if it is performed based on precise information and not the whole part is restored. It is also required to contain all the elements that are necessary to demonstrate its values and importance (integrity).
