WASHINGTON (AP) — The U.S. Interior Department has nominated 10 buildings in seven states designed by architect Frank Lloyd Wright — including the iconic home known as Fallingwater in western Pennsylvania — for inclusion on the World Heritage List of the world’s most significant cultural and natural sites.

U.S. Secretary of the Interior Sally Jewell announced the nominations Friday, saying Wright “is widely considered to be the greatest American architect of the 20th century.”

Wright’s buildings would become the nation’s first modern architecture on the list, which includes modern structures elsewhere such as the Sydney Opera House, the Bauhaus School in Germany, and Brasilia, the capital of Brazil.

Fallingwater, a National Historic Landmark in Mill Run about 65 miles southeast of Pittsburgh, was built over a waterfall and nestled into a rock mountainside.
