SPRING GREEN (WKOW) -- Frank Lloyd Wright's estate, Taliesin, has started tours in south central Wisconsin.
The famous architect used the property in Spring Green as a laboratory of sorts, changing and expanding it until he died in 1959.
Taliesin was declared a National Historic Landmark in 1976 by the National Park Service.
New this year are the four specialty tours, each scheduled one Friday per month during the regular tour season. They each have a theme: landscape, preservation, observation and biography.
The tours started Tuesday and run every day through October.
