Frank Lloyd Wright’s legacy stretches from coast to coast. The architect's most famous work is Fallingwater, a cantilevered home suspended over a Pennsylvania waterfall. But across the country, in California’s Bay Area, sits the Marin County Civic Center, remembered as Wright's last major design commission and only government project. To teach visitors about the sprawling horizontal complex, which links the tops of three separate hills, Curbed reports that Marin County’s Departments of Cultural Services has partnered with the county’s technology services to create an educational smartphone app.

Wright was selected to design the Marin County Civic Center in 1957, and the building was dedicated in 1962. The Civic Center app provides background information on both Wright’s role as designer and the complex's history, with blueprints, architectural plans, and photographs both old and new. (Sadly, the architect never saw his final vision realized: Wright died in 1959, at the age of 92, a year before the Civic Center’s groundbreaking.)

The app also has interactive features to help visitors navigate the enormous, 470,000-square-foot complex. There’s drone video footage of its insides, outsides, and grounds; a 360-degree virtual tour of Civic Center offices; and virtual peeks inside the Marin County Board of Supervisors Chambers, a Hall of Justice courtroom, and the Marin County Library.

Marin County’s new Civic Center mobile app is available for download in English and Spanish in the iTunes App Store and Google Play Store.
