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. The old Contra Costa County Courthouse (left) remains in use as the county's Finance Building. Both buildings are listed on the National Register of Historic Places.

The historic Contra Costa County Courthouse in Martinez, built in 1901, is a striking example of Beaux-Arts architecture with its grand columns and copper dome. Once the heart of county government, it now serves as a courthouse museum and symbol of the region’s legal and civic heritage.
