Hopewell Ceremonial Earthworks (Mound City) | USA

This property is a series of eight monumental earthen enclosure complexes built between 2,000 and 1,600 years ago along the central tributaries of the Ohio River. They are the most representative surviving expressions of the Indigenous tradition now referred to as the Hopewell culture. Their scale and complexity are evidenced in precise geometric figures as well as hilltops sculpted to enclose vast, level plazas. There are alignments with the cycles of the Sun and the far more complex cycles of the Moon. These earthworks served as ceremonial centres and the sites have yielded finely crafted ritual objects fashioned from exotic raw materials obtained from distant places.

San Antonio Missions (Mission Valero) | USA

The site encompasses a group of five frontier mission complexes situated along a stretch of the San Antonio River basin in southern Texas, as well as a ranch located 37 kilometres to the south.

The complexes were built by Franciscan missionaries in the 18th century and illustrate the Spanish Crown’s efforts to colonize, evangelize and defend the northern frontier of New Spain.

The 20th-Century Architecture of Frank Lloyd Wright (Fallingwater) | USA

The property consists of eight buildings in the United States 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 reflect the ‘organic architecture’ developed by Wright, which includes an open plan, a blurring of the boundaries between exterior and interior and the unprecedented use of materials such as steel and concrete. Each of these buildings offers innovative solutions to the needs for housing, worship, work or leisure. Wright's work from this period had a strong impact on the development of modern architecture in Europe.
