Frank Lloyd Wright was born in Richland Center, Wisconsin, in 1867. He began building this house in 1911, named Taliesin (Welsh, meaning "shining brow"), in Spring Green, Wisconsin. The better-known house is Taliesin West, but this one evolved over time, and he lived here most of his life.
I have not toured the house itself, which was closed to visitors when we went, but the Hillside Studio and Theatre are dramatic and moving to see. For more information, see the Wright in Wisconsin site.
