Architect: Frank Lloyd Wright
Location: Spring Green, Wis.
Year Built: 1911

It seems only fitting for Frank Lloyd Wright's summer home to be of equal stature to Fallingwater. The expansive three-wing building sits in a Wisconsin valley and stretches out onto the surrounding greenery. For this project, Wright constructed the chimneys and stone piers of the home out of local limestone and incorporated sand from the Wisconsin River into the stucco walls in his attempt to experiment with organic architecture. Wright started working on Talisin in 1911 after leaving his first wife because of his affair with another woman and her husband. It was also here Wright designed Fallingwater and the Guggeinheim.
