The
two-storied adobe barracks facing Sonoma’s central plaza was built
to house Mexican army troops under the command of General Vallejo. These
troops arrived in Sonoma in 1834. From then until 1846, Sonoma was the
headquarters of the commandant of the Frontera del Norte – the
Mexican Provincial of the north. Construction was completed in 1840
and ’41.
Following the Bear Flag takeover of Sonoma on June 14th, 1846, the barracks
housed a number of Bear Flag followers until July 9, when the Stars
and Stripes were first raised at Sonoma. Thereafter the barracks were
used by various United States forces. Throughout the next few years
Sonoma continued to be an important army post.
In later years it was used as a winery, store, law office and private
residence. It was purchased by the State in 1958.
