The Adobe Rios Caledonia
in San Miguel

The Adobe Rios Caledonia - a nicely restored late mission-era adobe that tells another part of the story of Mission San Miguel.

The Adobe Rios Caledonia represents the tail end of the founding period of the California Missions.

Built in 1835 (contrary to the date on the historic landmark plaque), it is located just a few hundred feet to the south of the Mission San Miguel in northern San Luis Obispo County.

Although it is only open Friday through Sunday, if you are visiting Mission San Miguel that time of the week, the Rios adobe will complete the picture of how people lived during those times.

The adobe also tells a later story, that of Highway 101 which grew to the thoroughfare it is today from the roots of the El Camino Real.

Adobes are so called because of the adobe blocks that form the walls. You can see the individual blocks in the photo where the protective plaster has worn away.

Depending on the height of the walls and the width of the building the walls might be a mass of adobe blocks 5 feet thick as they are in the mission churches.

The adobe blocks themselves are formed from soil with a high percentage of clay, straw or animal hair, manure and water. This mixture was then poured into a simple wooden form until it was somewhat set and then allowed to dry in the sun.

The Friends of the Adobe have been instrumental in restoring the adobe and making it into a museum of life in early San Miguel.

By the way, the name "Rios-Caledonia" refers to Petronilo Rios the builder and first owner of the adobe after the mission and lands were sold, and Caledonia was added by a later owner in 1868 to remind him of his Scottish roots. "Caledonia" is the name given to Scotland by the Romans.

The adobe Rios Caledonia later functioned as an inn, tavern and a Wells Fargo stagecoach stop until 1886. It is said that the Dalton Brothers and Frank and Jesse James visited here. It is credible since an uncle of the James boys was one of the founders of Paso Robles, owned property in the area and the gang was known to have traveled out west until conditions in the east "calmed down".

A very nice collection of historic artifacts have been donated to the adobe by area pioneer families.

These furnishings are authentic and give you a real taste of what life might have been like for early residents of Central California.
