A World Heritage Site is a place that is listed by the United Nations Educational, Scientific and Cultural Organization (UNESCO) as being of special cultural or physical significance. The list is maintained by the international World Heritage Programme administered by the UNESCO World Heritage Committee, composed of 21 UNESCO member states which are elected by the General Assembly.

As of July 2015, 1031 sites are listed: 802 cultural, 197 natural, and 32 mixed properties, in 163 states parties. According to the sites ranked by country, Italy is home to the greatest number of World Heritage Sites with 51 sites, followed by China (48), Spain (44), France (41), Germany (40), Mexico (33), and India (32). UNESCO references each World Heritage Site with an identification number; however, new inscriptions often include previous sites now listed as part of larger descriptions. Consequently, the identification numbers exceed 1,200, even though there are fewer on the list.
