World Heritage Sites in the United States


The United States is home to 22 of the 981 UNESCO World Heritage Sites across the globe. These sites are designated for their universal value in natural or cultural heritage and are places as unique and diverse as East Africa’s Serengeti, the Pyramids of Egypt, the Great Barrier Reef in Australia and the Grand Canyon in the U.S.

"World Heritage Sites represent an incredible opportunity for the United States to tell the world the whole story of America and the remarkable diversity of our people and beauty of our land,” Secretary of the Interior Sally Jewell commented after nominating the San Antonio Missions National Historic Park as a World Heritage Site in January 2014. “The San Antonio Missions represents a vital part of our nation’s Latino heritage and the contributions of Latinos to the building of our country.”
