Presidio of San Francisco (California Historical Landmark #79)

The Presidio of San Francisco is defined by the rows of stately brick barracks that line the Main Post parade ground. These structures, built in eighteen eighty-five, stand as lasting symbols of the site’s long evolution from a remote colonial outpost to the primary United States Army headquarters on the Pacific Coast. Established on September seventeenth, seventeen seventy-six, the Presidio began as a walled Spanish fortress designed to guard the entrance to the bay.
