The attached Gift Shop and separate Research Library buildings added in the 1920's. Located on the original San Miguel Mission property which was sold to William Reed and Petronillo Rios in 1846 by Governor Pio Pico. Using local Indian labor, Senor Rios constructed the two-story building as a hacienda for his family. From 1860 to 1886 this building was used as an inn and stage stop on the road from San Francisco to Los Angeles. Later it was used by various establishments. It gradually deteriorated. In 1964 the County of San Luis Obispo purchased the property. Major construction was completed in 1972. In 1978, the adobe, museum and gift shop were opened.

Today was a warm but beautiful day for the annual Pioneer Day Ladies Tea. It was held at the Estrella Warbird Museum, and several Historic Rios Caledonia members attended. It was wonderful to see everyone in person and to celebrate the Paso Robles Pioneer Day Queen, Belle, their attendants, and all the lovely ladies from our local pioneer families.

We are open THIS weekend and Pioneer Day weekend. Friday - Sunday 12 - 3. Come visit!
