A national priority protected site is the highest-level national protection for immovable cultural relics in China. The designation was first created under the 1961 Provisional Regulations on the Protection and Management of Cultural Relics, which evolved into the Law on the Protection of Cultural Relics.

According to the 2002 Cultural Relics Protection Law of the People's Republic of China, the National Cultural Heritage Administration of the State Council selects those with significant historical, artistic, and scientific value as national key cultural relics protection units. National key cultural relics protection units shall not be demolished; if they need to be relocated, they must be reported to the State Council for approval by applications from the people's government of the provincial administrative region.
