"[Taliesin] is the name of Wright’s home as well as the 800-acre architectural campus that includes buildings from nearly every decade of his career. Taliesin was Wright’s primary residence for 48 years from 1911 to 1959. It was his laboratory for architectural designs and innovation, and continues to serve the Taliesin community."
