National Register of Historic Places in Contra Costa County
In 1835, Mexico granted 13,326 acres, El Rancho Laguna de los Palos Colorados, to Joaquín Moraga and his cousin Juan Bernal. Six years later, Joaquín built this house, which is the oldest surviving adobe house in Contra Costa County.
The Joaquín Moraga Adobe was photographed in 1922 for the Historical American Building Survey (HABS). It has been restored and remodeled twice since then, first in 1941 and again in 1964 when it was incorporated into a private home.
When we tried to visit the Joaquín Moraga Adobe in 2006, the building was not visible from the public right-of-way. The Friends of the Joaquín Moraga Adobe are working to provide community access to the building and grounds.
The Joaquín Moraga Adobe is also California Historical Landmark 509.
