Frank Lloyd Wright's Faculty of Structure at Taliesin to shut | Training

The architecture school, which architect Frank Lloyd Wright founded almost 90 years ago, is closing, officials said on Tuesday.

The Taliesin School of Architecture, which includes Wright properties in Wisconsin and Arizona, will close in June.

The school board said in a statement that the "decision was made" after an agreement could not be reached with the Frank Lloyd Wright Foundation to continue operating the school.

Specific details of the negotiations between the school and the foundation were not disclosed.

"This is a sad and gloomy day for our school, our students and staff as well as the architectural community," said Dan Schweiker, Chairman of the Board of Governors.

Wright founded the architecture school in 1932. He and his young apprentices split their time between Taliesin in Spring Green, Wisconsin, and Taliesin West in Scottsdale, Arizona. The distinctive buildings at each location are open to the public.

The school currently has 30 students. It remains open for the spring semester. School officials say they are working on an agreement with Arizona State University's design school to allow these students' credits to be transferred.

Up until Wright's death in 1959 at the age of 91, Taliesin West was the famous architect's winter home and laboratory. The original Taliesin, Wright's primary residence in Spring Green, was named after a 6th century Welsh bard whose name means "shining forehead".

Both retreats were among the eight Wright-designed buildings recognized as UNESCO World Heritage Sites in July.
