The marker reads:
Watson School 1856-1967
In 1856 three Sonoma County pioneers banded together to rpomote the construction of a school for their own children and the children of Freestone, Bodega and Valley Ford. James Watson donated the land and was aided in this civic enterprise by William Riley Robertson and A.S. Purrine. Other families in the area donated time and materials necessary for construction of the Greek-revival schoolhouse. Redwood trees growing along Joy Road, which were milled locally, provided the lumber. Other families whose children attended school here included Lebaron, Wiley, Pallascio, Courtright and Parmeter. It believed to be the longest operating one-room school in California.
