the vacation home of Edgar J. Kaufmann is perched above Bear Run, a mountain stream in Mill Run, Pennsylvania. The home, which is called “Fallingwater,” was designed by Frank Lloyd Wright. Wright believed that “no house should ever be on any hill.” It should be of the hill, or belonging to it, said Wright, who was born on June 8, 1867. Fallingwater, with its ledges and lots of natural stone, is like a part of the forest.
