List of World Heritage Sites in the United States

The World Heritage Sites are places of importance to cultural or natural heritage as described in the UNESCO World Heritage Convention, established in 1972.[1] The United States of America ratified the convention on December 7, 1972, making its historical sites eligible for inclusion on the list.[2]

The first sites in the United States added to the list were Mesa Verde National Park and Yellowstone National Park, both at the Second Session of the World Heritage Committee, held in Washington, D.C. from September 5–8, 1978.[3] In total, 22 sites have been included, the most recent being Poverty Point in 2014.[2] The twenty-two sites are located in nineteen different states and two territories. California, Hawaii, Montana, and New Mexico each contain multiple sites, while two sites (Waterton-Glacier International Peace Park and Kluane / Wrangell – St. Elias / Glacier Bay / Tatshenshini-Alsek) are transboundary sites shared with Canada.

Mesa Verde National Park Montezuma County Colorado 6th to 12th centuries 27; 1978; iii The site contains a number of cliff dwellings constructed by the ancient Pueblo peoples between the 6th and 12th centuries at an altitude greater than 2,600 metres (8,500 ft). Some notable examples amongst the 600 dwellings include Cliff Palace, Balcony House, and Square Tower House. The dwellings were discovered in 1874. [4]
Yellowstone National Park Park, Teton, and Gallatin counties, Wyoming; Park County, Montana; Fremont County, Idaho Wyoming, Montana, Idaho N/A 28; 1978; vii, viii, ix, x The park consists of almost 9,000 square kilometres (9.7×1010 sq ft) of natural forest. The park contains half of the world's geothermal features including over 300 geysers, the world's largest concentration. In addition to its geographical sites, Yellowstone is significant for its natural history; nearly 150 species of fossil plants have been discovered within the park. [5]
Kluane / Wrangell – St. Elias / Glacier Bay / Tatshenshini-Alsek Valdez-Cordova Census Area, Yakutat City and Borough, Southeast Fairbanks Census Area, Hoonah–Angoon Census Area Alaska (shared with Canada) N/A 72; 1979, 1992 (extended), 1994 (extended); vii, viii, ix, x The joint United States–Canada site located along the border between the two countries comprise the world's largest non-polar ice field and some of the world's longest glaciers. The region is also the natural habitat for a number of species including grizzly bears, caribou, Dall sheep, and every species of Alaskan salmon, some in greater numbers than found anywhere else. [6]
Grand Canyon National Park Coconino and Mohave counties Arizona N/A 75; 1979; vii, viii, ix, x The centerpiece of the park is the Colorado River. The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile (6,000 feet or 1,800 metres). Nearly two billion years of the Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted [7]
Everglades National ParkIn danger Miami-Dade, Monroe, and Collier counties Florida N/A 76; 1979; viii, ix, x The park is the largest designated subtropical wilderness reserve in North America. Featuring a variety of wetlands and forests, it has become a sanctuary for a large number of birds, reptiles, and threatened or protected species. The property was placed on the List of World Heritage in Danger in 2010 due to degradation of the property resulting in a loss of marine habitat and decline in marine species. The property was previously listed as in danger from 1993–2007 due to sustained hurricane damage and deterioration of water flow and quality due to agricultural and urban development. [8][9]
Independence Hall Philadelphia Pennsylvania 1753 (constructed), 1776, 1787. Steeple demolished 1781, replaced with new design 1828.

[13]

La Fortaleza and San Juan National Historic Site San Juan Puerto Rico 15th to 18th centuries 266; 1983; vi These structures were built between the 15th and 19th centuries to defend the harbor of San Juan, and are examples of European military architecture adapted to port cities on the American continent.

The historic site also comprises Castillo San Felipe del Morro, Castillo de San Cristóbal, El Cañuelo, and three-fourths of the old city wall. [18]
Statue of Liberty New York City New York 1886 307; 1984l i, vi Designed by Frédéric Bartholdi, the statue was a gift to the United States from the people of France. It has since become an icon of freedom and of the United States, and a welcoming signal to immigrants arriving from abroad. [19]
Yosemite National Park Tuolumne, Mariposa and Madera counties California N/A 308; 1984; vii, viii Formed as a result of repeated glacial erosion of granitic bedrock over 10 million years, the park contains a unique diverse landscape of spectacular granite cliffs, waterfalls, clear streams, Giant Sequoia groves, and biological diversity. [20]
Chaco Culture National Historical Park San Juan and McKinley counties New Mexico 10th to 12th centuries 353; 1987; iii Formerly a major center of culture for the Ancient Pueblo Peoples, the park preserves one of the United States' most important pre-Columbian cultural and historical areas, hosting the densest and most exceptional concentration of pueblos in the American Southwest. [21]
Hawaii Volcanoes National Park Hawaii County Hawaii N/A 409; 1987; viii The park is home to Kīlauea and Mauna Loa, two of the most active volcanoes in the world. The volcanic eruptions in the area have resulted in frequently changing landscape, and rare flora and fauna. [22]
Monticello and the University of Virginia Albemarle County and Charlottesville Virginia 18th and 19th centuries 442; 1987; i, iv, vi Built between 1769 and 1809, Monticello was the plantation home of its designer, third President of the United States and author of the Declaration of Independence, Thomas Jefferson.

The most prominent of these, The Rotunda, is a half-scale model of the Pantheon in Rome. [23]
Taos Pueblo Taos New Mexico 13th and 14th centuries 492; 1992; iv The site is an ancient pueblo belonging to a Native American tribe of Pueblo people, marking the cultural development in the region during the Pre-Columbian era. [24]
Carlsbad Caverns National Park Eddy County New Mexico N/A 721; 1995; vii, viii The park contains over 100 limestone caves, including Carlsbad Caverns and Lechuguilla Cave, which exhibit rare and unique speleothems.

Waterton-Glacier International Peace Park Flathead and Glacier counties Montana (shared with Canada) N/A 354; 1995; vii, ix The joint United States–Canada site located along the border between the two countries has a unique, distinctive climate, physiographic setting, mountain-prairie interface, and tri-ocean hydrographical divide. [26]

The area supports 7,000 species, one quarter of which are endemic. The area is regarded with traditional significance for living Native Hawaiian culture, as an embodiment of the Hawaiian concept of kinship between people and the natural world. The monument also contains the pre-European archaeological sites on the islands of Nihoa and Makumanamana. [27]
Monumental Earthworks of Poverty Point West Carroll Parish Louisiana 1650 BCE 1435; 2014; iii The vast earthen architecture of this site was constructed by a foraging society of hunter- gatherers, not a settled agricultural people, which makes it all the more remarkable a site. It is still not understood how and why such a society could so totally transform this landscape. It may well be the largest hunter-gatherer settlement that has ever existed. Not only was it the largest settlement of its time in North America, but its design was absolutely unique and its construction required an unprecedented amount (over 750,000 cubic meters) of earth-moving. Poverty Point was also the center of a major exchange network with goods brought in from as far as 1,600 kilometers (1,000 miles) distant. [28]
