Courthouse History - Built in part by inmate chain gangs from 1901 to 1903 and now a National Historic Site, the old Contra Costa County Courthouse (left) remains in use as the county's Finance Building. The cupola, used as a watchtower during blackouts in World War II, was removed in 1957 for reasons of earthquake safety. In 1966, most of the courts' offices moved into the Hall of Records (right), which was completed in 1933 and continues to serve as the county's courthouse. Both buildings are listed on the National Register of Historic Places.
