Sonoma County Historical Society list of landmarks

The Sonoma County Historical Society (SCHS) has established a master list of historical landmarks in Sonoma County.[1]

This list is intended to provide a complete listing of all landmarks established by federal, state, county city/town governments in the county and independent organizations.[1]

Five cities have historical landmark programs: Santa Rosa,[2] Sonoma,[3] Petaluma,[4] Healdsburg[5] and Windsor.[6] Four cities do not have a program: Sebastopol, Cotati, Cloverdale and Rohnert Park. The County of Sonoma's official designated landmarks are numbered from 1 to 192, but some landmarks have been removed from the list and those numbers are not active.[7]
