The San Diego County Administration Center is a historic Beaux-Arts/Spanish Revival-style building in San Diego, California. It houses the offices of the Government of San Diego County. It was completed in 1938 and was primarily funded by the Works Progress Administration. It was previously known as the San Diego Civic Center and as the City and County Administration Building. Because of its notable architecture and its location fronting San Diego Bay, it is nicknamed the Jewel on the Bay. Architects were Samuel Wood Hamill, William Templeton Johnson, Richard Requa and Louis John Gill. The building used innovative construction techniques to guard against earthquakes, and the project was considered to be "a prototype of American civic center architecture". The building was listed on the National Register of Historic Places on May 16, 1988.
