List of World Heritage Sites in the United States facts for kids
The United Nations Educational, Scientific and Cultural Organization (UNESCO) helps protect amazing places around the world. These special spots are called World Heritage Sites. They are important because of their unique culture or incredible natural heritage.
Cultural heritage means things like old buildings, sculptures, or important historical places. Natural heritage includes beautiful landscapes, special rock formations, or homes for rare animals and plants.
The United States joined this effort in 1973. Today, there are 25 World Heritage Sites in the U.S. Plus, there are 18 more places that might become sites in the future!
The very first U.S. sites added to the list in 1978 were Mesa Verde National Park and Yellowstone National Park. The newest site, added in 2023, is the Hopewell Ceremonial Earthworks. These 25 sites are found in 22 different states and two U.S. territories. Some states like Arizona, California, and New York have more than one site. Two sites are even shared with Canada!
Out of the 25 sites, 12 are cultural, 12 are natural, and one, Papahānaumokuākea, is a mix of both. Sadly, one site, Everglades National Park, is currently listed as endangered. This means its amazing water systems are in trouble.

Amazing World Heritage Sites in the U.S.
UNESCO uses ten special rules to decide if a place can be a World Heritage Site. Each site must meet at least one of these rules. Rules 1 to 6 are for cultural sites, and rules 7 to 10 are for natural sites.
