The Marin County Civic Center, designed by Frank Lloyd Wright, is located in San Rafael, California, United States. Groundbreaking for the Civic Center Administration Building took place in 1960, after Wright's death and under the watch of Wright's protégé, Aaron Green; it was completed in 1962. The Hall of Justice was begun in 1966 and completed in 1969. Veterans Memorial Auditorium opened in 1971, and the Exhibit Hall opened in 1976. Located away from the former county seat in downtown San Rafael, the expansive complex stretches across two valleys just east of US 101. Its pink stucco walls, blue roof and scalloped balconies are distinctive. The smaller wing is the county administration building and the larger wing is the Hall of Justice, joined by a round structure on a small hill that houses a branch of the Marin County Free Library. A battle between factions of the Marin County Board of Supervisors played out through the selection of the site and the architect, the financing of the project, and its eventual completion. The Marin County Civic Center is a state and National Historic Landmark. The nearby fairgrounds hosts the Marin Sonoma Concours d'Elegance each spring and the Marin County Fair in July. Architecture The selection of Frank Lloyd Wright in 1957 to design the Civic Center was controversial. The Civic Center project was Wright's largest public project, and encompassed an entire campus of civic structures. The post office was the only federal government project of Wright's career. Wright's design borrowed ideas and forms from Wright's Broadacre City concept, first published in 1932. Main building The principal structure consists of a four-story, long Administration Building and a three-story, long Hall of Justice at a lower elevation, joined at a 120-degree angle with an diameter rotunda. The Hall of Justice spans a small valley, arching twice over an access road and a parking area, while the Administration Building spans a smaller ravine. Both structures are entered through archways on their lower levels. The long principal facades are marked by shallow non-structural arches of decreasing span with each story. The arches, which are framed in metal with a stucco appliqué, overlap slightly at the lower level. On the intermediate level, they appear to stand on short slender gold-anodized columns, and on the top level, they become round openings with gold railings directly under the deep roof overhang. The railings themselves have a circular
