The United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Sites are places of importance to cultural or natural heritage as described in the UNESCO World Heritage Convention, established in 1972. Cultural heritage consists of monuments, groups of buildings, and sites. Natural features, geological and physiographical formations, and natural sites which are important from the point of view of science, conservation or natural beauty, are defined as natural heritage. Dominican Republic accepted the convention on February 12, 1985, making its historical sites eligible for inclusion on the list. As of 2023, Dominican Republic has only one World Heritage Site, Colonial city of Santo Domingo, which was inscribed in 1990.
