History
The Ohlone village of Pruristac was located on the site. The San Pedro Valley provided the Ohlones with an abundance of food and raw materials. In 1786, Spanish padres found it difficult to grow enough food at Mission Dolores. They created an asistencia named San Pedro y San Pablo. This mission outpost was a support farm where crops such as corn and wheat were grown. The asistencia building included living quarters for the padres, a chapel, workrooms and storage for grain. In 1839, Mexican Don Francisco Sanchez was granted Rancho San Pedro. The boundaries of his land grant roughly parallel those of the present-day City of Pacifica. Sanchez raised cattle for the hide-and-tallow trade. When ships came to California, Sanchez could trade his hides for manufactured items. He built the Sanchez Adobe as a home for his family between 1842-1846. It is the second oldest building in the county.
