Presidio of Sonoma

The Presidio of Sonoma is a restored military settlement with adobe buildings featuring thick earthen walls arranged in a rectangular layout around a central plaza in northern California. The barracks, officers' quarters, and parade ground demonstrate the characteristic design of a Spanish-Mexican garrison from this era.

Founded in 1836 by General Mariano Vallejo, this garrison was built to protect Mexican interests and observe Russian expansion along the California coast. The site later became the scene of armed conflict during California's transition to United States control.

The site marks a meeting point of Native American, Spanish, Mexican, and American presence, visible in how the buildings blend architectural styles from these different periods.

The site is best explored on foot, with different areas clearly marked and accessible including barracks, residences, and the open parade ground. Plan to spend a few hours walking through the grounds, and wear suitable footwear for uneven surfaces and outdoor terrain.

In 1846, American settlers took over the Presidio during the Bear Flag Revolt, a brief declaration of California independence that lasted only weeks before the United States took control. This moment marked a turning point in who governed the territory.
