The City of Sonoma was incorporated on September 3, 1883.

Surrounding this plaza are significant 19th-century adobe buildings including Mission San Francisco Solano and the Sonoma Barracks, once used by the Mexican military. Shops, tasting rooms, restaurants, bakeries, and a historic theater line the streets around the Sonoma Plaza.
