UNESCO World Heritage Sites in the USA

United States Cultural and Natural Heritage Sites as Designated by UNESCO

The United Nations Educational, Scientific, and Cultural Organization, known as UNESCO, has been designating natural and cultural landmarks important to the world's heritage since 1972. Sites on the UNESCO World Heritage List are afforded special status, which enables them to receive international funding and assistance to preserve these treasures.

The United States has nearly two dozen natural and cultural World Heritage Sites on the UNESCO list, with at least a dozen more on the tentative list. Following are all of the United States' World Heritage Sites and links to more information about them.
