As a personal affront to Don Guido, I will be celebrating the greatest American Architect of the 20th century - one Mr. Frank Lloyd Wright, with rotating Avys of his finest works each week.
This week, Fallingwater.

I have been fortunate enough to take in the masterpiece in person. It's literally built in a real waterfall.
>>Time cited it after its completion as Wright's "most beautiful job";[5] it is listed among Smithsonian's Life List of 28 places "to visit before you die."[6] It was designated a National Historic Landmark in 1966.[3] In 1991, members of the American Institute of Architects named the house the "best all-time work of American architecture" and in 2007, it was ranked twenty-ninth on the list of America's Favorite Architecture according to the AIA.<<
