The UNESCO World Heritage Committee announced in early July that eight works designed and constructed in the United States by architect Frank Lloyd Wright in the first half of the 20th century have been added to the UNESCO World Heritage List. The committee awarded this recognition to Wright because of his unprecedented use of steel and concrete, his blending of interior and exterior and his organic architecture, which have had a strong impact on architecture worldwide. The works added to the list include »Fallingwater«, constructed in the Allegheny Mountains between 1935 and 1939 for Pittsburgh-based department store owner Edgar J. Kaufmann, and the Solomon R. Guggenheim Museum in New York City, which first opened in 1959.
