Marker text: RIOS-CALEDONIA ADOBE
This imposing building is an excellent example of California Mexican Era architecture. Using Indian labor, Petronilo Rios built the two-story Adobe about 1846 as his residence and headquarters for sheep and cattle operations. Named "Caledonia" in the 1860's it served as a hotel and stage stop between Los Angeles and San Francisco until 1886. Restoration began in 1968 by the Friends of the Adobes.
