Two new short films spotlight San Mateo County history:

The Ohlone-Portolá Heritage Trail

This film provides an overview of the first contact between the native people of the San Francisco Peninsula and European explorers in 1769. Learn more about the effort to tell the history of the native Ohlone people who lived in the area and were instrumental in supporting the Spanish Portolá expedition with the creation of a heritage trail.

The Sanchez Adobe: A Crossroads of History

Don Francisco Sanchez, owner of Rancho San Pedro, built the Sanchez Adobe between 1842-1846. Today, it is a San Mateo County Park operated by the San Mateo County Historical Association.

The site is rich in history -- it was first home to a native Ohlone village, then was used by the Spanish, Mexicans and early Americans for a variety of uses. The site is now a County park operated in cooperation with the San Mateo County Historical Association. Learn more.
