Ten Frank Lloyd Wright buildings from seven states, including L.A.'s Hollyhock House, were nominated on Friday for the UNESCO World Heritage List, which recognizes the most notable sites -- cultural and natural -- around the globe.
The nomination was made by U.S. Secretary of the Interior Sally Jewell, who said Wright was “widely considered to be the greatest American architect of the 20th century.”
“His works are a highly valued and uniquely American contribution to the world’s architectural heritage,” Jewell said in a statement.
Other American sites already on the list include Monticello, the Statue of Liberty and the Grand Canyon.
If the Wright structures are selected by the UNESCO World Heritage Committee in summer 2016, they’d represent the first examples of modern architecture in the U.S. to be recognized. Other examples of modern architecture on the list, from other countries, include the Sydney Opera House in Australia and the Bauhaus School in Germany.
Hollyhock House is located in the Barnsdall Art Park in Hollywood. It was named a National Historic Landmark in 2007. After $4.3 million in renovation and conservation that was completed last year, the house is scheduled to be reopened to the public Feb. 13.
Apart from Hollyhock, the Wright buildings chosen by Jewell -- all built between 1906 and 1969 -- include Fallingwater in Mill Run, Pa.; the Solomon R. Guggenheim Museum in New York City; the Marin County Civic Center in San Rafael, Calif.; Unity Temple in Oak Park, Ill.; Frederick C. Robie House in Chicago; Taliesin in Spring Green, Wis.; the Herbert and Katherine Jacobs House in Madison, Wis.; Taliesin West in Scottsdale, Ariz.; and Price Tower in Bartlesville, Okla.
