The 10 Most Amazing Unesco World Heritage Sites In The US

Yellowstone National Park, created in 1872, is a vast natural forest of 3,500 square miles that spans the states of Wyoming, Montana, and Idaho. More than half of the world's geothermal phenomena can be observed here, with some 10,000 different examples. It also has more than 300 geysers, which is about two-thirds of all the geysers on the planet.

This location, the first national park in the United States, has been a World Heritage Site since 1978. It is also known for protecting abundant and diverse wildlife —such as grizzly bears, wolves, bison, and wapiti— and for drawing millions of visitors from all over the world each year. And you, have you ever been?

The Independence Hall, located in historic Philadelphia, was designated a World Heritage Site in 1979. This location, far more than just a building, is considered the birthplace of America’s political foundation. The Assembly Room of the Pennsylvania State House, now known as Independence Hall, is where the Declaration of Independence was signed in 1776. And just 11 years later, the United States Constitution was also debated and signed here.

This Georgian-style red brick structure was designed by Scottish lawyer Andrew Hamilton and completed in 1753 to house the colonial assembly of the Province of Pennsylvania. In the 19th and 20th centuries, it was then renovated several times. In 1966, the building was recognized as a National Historic Landmark by the U.S. government and is currently the centerpiece of the Independence National Historical Park.

Installed in 1886 at the gate of New York’s harbor, the Statue of Liberty has since welcomed millions of immigrants who have come to populate the United States. This colossal neoclassical 305-foot-tall effigy enlightening the world with its torch was made in Paris by the sculptor Frédéric Auguste Bartholdi in collaboration with Gustave Eiffel. It was a gift from France to our country on the occasion of the centenary of our independence.

To visit this historic monument, declared a UNESCO World Heritage Site in 1984, tickets must be purchased in advance. Or you can always ride the fare-free Staten Island ferry and admire it from afar in all its splendor!

Located in the southwest of Colorado, the Mesa Verde Plateau reaches an altitude of over 8,500 feet. The National Park was established in 1906 and was added to the list of American World Heritage Sites in 1978. This location hosts a large number of Pueblo Indian dwellings built between the 6th and 12th centuries. Some 4,400 settlements have been found, including villages built high up on the plateau and imposing stone-built homes on rocky outcrops, with more than a hundred rooms in some cases.

The Mesa Verde National Park, which nowadays protects these invaluable archaeological sites, is a testament to the ancient cultural traditions of Native American tribes and is among the best preserved in the United States. If you haven’t visited yet, you must! We guarantee you a spectacular window into the past!

Hawaii Volcanoes National Park is located on the southernmost Hawaiian island and was founded in 1916. It is best known for its extraordinary biodiversity spread over more than 340,000 acres, and it is in fact thanks to this natural richness that UNESCO declared it a World Heritage Site in 1987.

The park, as you would have guessed, is home to several volcanoes. Although many of them are currently inactive, two are very much alive: Mauna Loa, which last erupted in 1984, is known to be still active and is considered the world's greatest volcanic mass; Kīlauea is more than 200,000 years old and has been erupting since 1983, the most recent occurring on June 3, 2024.

If you are considering visiting the park, exploring the volcanoes, and enjoying a unique experience, we also recommend a museum tour, where you can learn all about the history of these fascinating fiery peaks.

The Monticello Residence in Virginia, designed by Thomas Jefferson, the third president of the United States, is one of the finest examples of American neoclassical architecture. Since 1987, it has been on the UNESCO World Heritage List, along with the University of Virginia in Charlottesville.

Jefferson created Monticello as his plantation mansion and envisioned the university as the ideal ‘academic village’. His vision of architecture, based on classical antiquity, reflects not only his aspirations for a new American republic heir to the European tradition but also the degree of cultural experimentation that could be expected of a country in the process of democratic evolution.

Papahānaumokuākea, made up of a series of 583,000 square miles of small islands, atolls, and surrounding marine wilderness, is located in northwest Hawaii. This particular location has enormous natural value as one of the largest marine protected areas in the world. It is equally important for its Native culture. Two of its islands, Nihoa and Makumanamana, bear archaeological remains that attest to the presence of human settlement even before the arrival of Europeans. For Hawaiians, this site has cosmological significance, as it represents the bond between humans and nature.

Papahānaumokuākea was designated a World Heritage Site in 2010, and although it’s not currently open to the general public, it continues to be accessible for research, habitat restoration, and cultural and educational purposes.

Grand Canyon National Park is known as one of the seven natural wonders of the world and has been a UNESCO World Heritage Site since 1979.

Located in the state of Arizona, this park is divided by a gigantic steep-sided canyon carved by the Colorado River, which, at more than 6,000 feet deep, is the most spectacular gorge in the world. This site is so relevant that all the geological history of the last two billion years can be found in its horizontal strata. And across its 277 miles, there are even traces of prehistoric man's efforts to adapt to a particularly inhospitable environment.

If you haven’t visited it yet, you should soon join the more than 5 million people traveling each year!

This 2015 World Heritage Site, built on what was once the border of New Spain along the San Antonio River, constitutes five mission complexes that reflect the history of the region.

Founded by Franciscan missionaries in the 18th century, San Antonio includes architectural structures, archaeological remains, churches, dwellings, farmland, silos and water supply systems.

This site, located in Texas, is a living testament to the Hispanic monarchy's enterprise to colonize, evangelize, and defend the northern frontier territories of New Spain. These missions are also an example of the mixture of Hispanic and Coahuila culture, as can be seen in the ornamental elements of the churches that mix Catholic symbolism with native naturalist aesthetics.

This series of eight Frank Lloyd Wright works recognizes the famous architect's influence on modern design. The most relevant buildings included in the 2019 Unesco designation are Fallingwater House in Mill Run, Pennsylvania; Unity Temple Church in Oak Park, Illinois; Herbert and Katherine Jacobs House in Madison, Wisconsin; and the Solomon R. Guggenheim Museum of Art in New York City, among others.

These sites are a great example of the ‘organic architecture’ conceived by Wright, characterized by open plan design, the blurring of the boundaries between inside and outside, and the highly original use of materials such as steel and concrete. Wright's innovative conception of architecture, whether in residential, work, cultural, or religious buildings, greatly influenced the evolution of modern architecture in Europe and the United States and is still a point of reference for designers today.
