Step In. Look Back.
Your Historic Journey Starts Here!
Housed in the iconic 1921 Tomales High School Auditorium, the Tomales Regional History Center preserves and inspires interest in the region’s history through its archives, collections, exhibitions, and interpretation; and develops an awareness of the role we all play on the greater continuum of that history. We chronicle the stories and heritage of the region spanning from Point Reyes Peninsula north to Bodega Bay, including the western reaches of Marin and Sonoma Counties.

Telling Stories of Mexican California: Real Life & Myth Making: This traveling exhibition from the California Historical Society (via Exhibit Envoy) examines the true history of California’s Mexican era (1822–1846) alongside the romanticized "Spanish Fantasy Past" created by early boosters. Custom companion panels curated by the History Center bring this narrative home to West Marin, highlighting regional Coast Miwok heritage, Mexican land grant ranchos, and the local families who shaped the Tomales Bay region.
