Watson School in western Sonoma County preserves a one-room schoolhouse on its original site near Bodega, created from land donated by James Watson in 1855 to serve Freestone, Bodega, and Valley Ford. Open from 1856 to 1967, it operated for 111 years, longer than any other one-room public school in California. The building remains in its original condition, offering a rare connection to the region’s rural educational past. The site gained landmark recognition in the 1970s, later received restoration support from Daniel B. Furlong’s estate in 2011, and today remains a small county park with basic visitor facilities.
