This Mission Revival Style building in Gustine, the only surviving one of four constructed in 1911, served as a justice court and as Township No. 6's jail from 1911 to 1980. Leased by the Gustine Historical Society in 1985 and refurbished with the aid of many donations and volunteers, it reopened in 1990 as the Gustine Museum. On August 11, 1995, it was designated a California Point of Historical Interest.
