UNESCO World Heritage Sites are places around the world that have important significance to people. When a place is designated a UNESCO Site, it’s considered a place for the people. The country, location, or purpose doesn’t matter. It’s a place all people can go and visit and see the history. There are UNESCO Sites in America, as well as many other countries.

While the United States doesn’t have as many sites as some other countries, it does have several worth visiting if you’re ever in the area. Check them out below.

How Many UNESCO Sites Are There in America?

You might expect a large country like the United States to have a large number of UNESCO Sites, but it really doesn’t. There are only 25 sites in the United States.

The main reason that there are so few is that most of them are nature sites. While America has a long history, a lot of the buildings and structures by people who originally lived on the land were lost or taken down. So there aren’t as many cultural sites to list, unlike places like Italy.

Half (12) of the UNESCO sites are cultural, and half are natural. There’s also a mixed one, to round the number up to 25.

Which UNESCO Sites Are the Best to Visit?

Though there are only 25 UNESCO World Heritage Sites, the ones available are truly stunning.

1. Carlsbad Caverns National Park

These caves are quite impressive, and worth a tour if you’re in the area.

Carlsbad Caverns National Park is in New Mexico. It’s been a site since 1995. The area is home to more than 118 caves that formed when sulfuric acid dissolved the limestone in the area.

2. Everglades National Park

The Everglades are a huge series of swamps and grasslands, of which the Everglades National Park only covers 20 percent.

  • Unity Temple in Illinois
  • Taliesin West in Arizona
  • The Frederick C. Robie House in Illinois

The Great Smoky Mountains National Park reaches through two states, Tennessee and North Carolina. It’s been a Heritage Site since 1983. This national park is full of beautiful scenery and over 3,000 plant species.

6. Independence Hall

Passerbys might think this to be the same as any other old building, not realizing this is where very important documents were signed.

This historic building has been a World Heritage Site since 1979. It’s located in Pennsylvania. It’s not a remarkable building on its own, but it’s where the Declaration of Independence and the Constitution were signed. It might not be the absolute best UNESCO Site in America, but it’s definitely full of important American history.

7. Glacier Bay

It’s hard to believe how captivating ice can be, but there’s no denying that this view is absolutely stunning.

This site goes by many names in Alaska and Canada. Some of its names include Kluane, Wrangell-St. Elias, and Tatshenshini-Alsek. This World Heritage Site is made up of a series of glaciers. It’s the largest non-polar ice field in the world and is made up of some of the longest glaciers. Different parts of the area were designated at different times, from 1979 to 1994.

8. Mesa Verde National Park

Mesa Verde National Park is home to impressive and sturdy abodes, such as the one in the picture above.

Despite having a history that dates back to 450 CE, the Mesa Verde National Park wasn’t designated until 1978. This park is home to ancient Puebloan buildings and cliff dwellings, such as the Cliff Palace and Balcony House.

9. Redwood National and State Park

The impressive trees are large, sturdy, and very, very old.

Designated in 1980, this park in California is home to beautiful and large redwood trees. These trees date back to over 160 million years ago, making them some of the oldest living organisms in the world. There are many other incredible animals and plants in the area, such as the California brown pelican, tanoaks, and sea lions.

10. The Statue of Liberty

When bringing up America, it’s hard not to think about the Statue of Liberty. Not only is it one of the symbols of America, but it’s one of the monuments to symbolize the ideals America stands behind, such as freedom and liberty. It became a UNESCO site in 1984.

11. San Antonio Missions

These missions were part of Spanish Catholic religious groups to help spread the religion.

The San Antonio Missions are examples of structures made when Spain still had control over Texas. Most of the missions from this time still stand today. One of the most famous is the Alamo, which is an important part of Texas history. These are relatively new to the UNESCO list, designated in 2015.
