Casa Grande Servants' Quarters
East Spain Street
Built 1840

General Vallejo built his first home, Casa Grande, here. The wide second-story balcony overlooked the Plaza.

On the morning of June 14, 1846, a group of thirty to forty American settlers and frontiersmen known as the Bear Flag Party “arrested” General Vallejo at Casa Grande and had him imprisoned at Sutter’s Fort. They announced the establishment of a free and independent Republic of California and raised a new, homemade flag in the Plaza.

The main wing of Casa Grande was destroyed by fire on February 12, 1867. Only the two-story servants’ quarters stands today.
