National Register of Historic Places in Sonoma County

National Register #92000293
Sonoma Plaza Boundary Increase
Center of Sonoma
Built 1835 By Mexico

Sonoma was the last town under Hispanic control laid out under the Laws of the Indies. Sonoma retains its integrity to this plan with the size and location of the Plaza, orientation of the buildings, and the grid pattern of streets surrounding the Plaza.

General Mariano Guadalupe Vallejo laid out the pueblo in 1835. He brought in the earliest settlers and supervised the dissolution of Mission San Francisco Solano.

The first commercial wineries in California were established here. Other early industries included stone quarrying and fish ranching.

This historic district is the northernmost outpost for adobe buildings in the Monterey architectural style. Later residential and commercial buildings are textbook examples of architectural styles popular in America between the years 1835 and 1945: Classical Revival, Italianate, Eastlake, Queen Anne and bungalow.
