Millions of travelers visit UNESCO World Heritage Sites every year. Scattered all over the world, they are cultural or natural sites that have outstanding value to humanity.

While many Americans travelers are part of this immense World-Heritage-seeking group, relatively few realize we also have many UNESCO sites in the USA. In fact, with an additional two U.S. sites recently added, there are now a total of two dozen sites in the USA.

Worldwide, UNESCO sites range from the well known – the Cathedral of Notre-Dame in France, the Historic City of Ayutthaya in Thailand, the Tower of London in England, for example – to such lesser-known places as the Matobo Hills in Zimbabwe, East Rennell in the Solomon Islands and the Struve Geodetic Arc in Moldova.

You may not have heard of many of them but they are all exceptional places that need protection for future generations.

Today there are more than 1100 designated sites on the World Heritage List in 161 countries, many of which are of exceptional interest to travelers.

The  following is a roundup of the 24 UNESCO World Heritage Sites in the USA that you’ll find closer to home.

They also include the date of their inclusion on the list, as well as GPS coordinates to map your trip, since most people will likely visit by car, perhaps on a enjoyable road trip. All are listed by their region in the USA.

UNESCO World Heritage Sites in the Eastern USA

Independence Hall (1979)

America’s Independence Hall is certainly the centerpiece of Independence National Historical Park in Philadelphia. Both the Declaration of Independence (1776) and the Constitution of the United States (1787) originated in this building. The universal principles of freedom and democracy outlined in these documents are of fundamental importance to American history and have also had a profound impact on lawmakers worldwide.

• Location: Chestnut Street between 5^th and 6^th Streets in downtown Philadelphia.
• GPS: N39 56 55 W75 9 0

Monticello and the University of Virginia in Charlottesville (1987)

Thomas Jefferson (1743–1826), author of the American Declaration of Independence and the third president of the United States, was also a talented architect of neoclassical buildings. He designed Monticello (1769–1809), his plantation home, and his ideal ‘academical village’ (1817–26), which is still the heart of the University of Virginia.

Additionally, Jefferson’s use of an architectural vocabulary based upon classical antiquity symbolizes the aspirations of the new American republic as the inheritor of European tradition and the cultural experimentation that could be expected as the country matured.

• Location: central Virginia, 70 miles northwest of Richmond.
• GPS: N38 1 58 W78 30 14

Statue of Liberty (1984)

The world-renowned Statue of Liberty was made in Paris by the French sculptor Bartholdi. It was also built in collaboration with Gustave Eiffel who was responsible for the steel framework. Their masterpiece, ”The Statue of Liberty Enlightening the World,” was a gift of friendship from France to the United States. It is still a universal symbol of freedom and democracy.

Despite Liberty Island only being reachable by ferry, approximately 3.5 million people visit the Statue every year.

Many endangered animal species also survive there, including what is probably the greatest variety of salamanders in the world. Surprisingly to many, it is America’s most visited national park.

• Location: Great Smoky Mountains National Park straddles the border between North Carolina and Tennessee.
• GPS: N35 35 35 W83 26 8

The 20th-Century Architecture of Frank Lloyd Wright (2019) (Multi-Region)

The entire site consists of eight buildings designed by the architect during the first half of the 20th century. These include well-known designs such as Fallingwater (Mill Run, Pennsylvania) and the Guggenheim Museum (New York).

All the buildings also reflect the ‘organic architecture’ developed by Wright, which blurs the boundaries between exterior and interior and the unprecedented use of steel and concrete. Each offers innovative housing, worship, work, or leisure solutions. Additionally, Wright’s work from this period substantially impacted the development of modern architecture in Europe.

Equally important, it is a striking example of a complex chiefdom society, with many satellite mound centers and numerous outlying hamlets and villages. Incredibly, this agricultural society may also have had a population of 10–20,000 at its peak between 1050 and 1150.

Chaco is remarkable for its monumental public and ceremonial buildings and distinctive architecture – it has an ancient urban ceremonial center unlike anything constructed before or since.

Not surprisingly, the area has deep cosmological and traditional significance for living Native Hawaiian culture as an ancestral environment, the embodiment of the Hawaiian concept of kinship between people and the natural world, and where it is believed that life originates and where the spirits return after death.

On two islands, Nihoa and Makumanamana, archaeological remains relate to pre-European settlement and use. Much of the monument comprises pelagic and deep-water habitats, with notable features such as seamounts, submerged banks, extensive coral reefs, and lagoons.
