The office of famed architect Frank Lloyd Wright is now on permanent display at the Hagen History Center.

Also on display, Wright's "Butterfly Bridge" design. 

The 17-foot model of the bridge was designed to connect  San Francisco and Oakland across the bay, with a reinforced concrete bridge.

He designed more than 1,000 structures over a 70-year period.   

The COVID-19 pandemic closed the center for a year and a half, but it's set to reopen this weekend.

There are two free sessions for local residents to enjoy this weekend.

Saturday from 11:00 am until 6:00 pm.

Sunday hours are from 11:00 am until 4:00. 

The Hagen History Center is located on 356 West 6th Street and regular museum hours will start on July 20.
