Its exterior combines revivalist fortress design with early twentieth-century machine age construction, and its interior was among the most ornate of any armory. It was also built as a social center for the city and served as home to the Coastal Artillery and later the 250th Coast Artillery.","narrative":"Occupying a full block at Fourteenth and Mission Streets, this armory and arsenal was built from September 1912 to June 1914 to designs by Woollett & Woollett, with McLeran & Peterson as contractor. It was designed to resemble a medieval fortress, with four octagonal corner towers, rough clinker brick walls, narrow slit windows, and sandstone and limestone trim. A huge barrel-vaulted drill hall with curving steel girders spans 170 feet at the rear. The building cost $480,000 and housed coast artillery companies, naval militia, a signal corps, and an indoor rifle range, along with a pool, gymnasium, ballroom, and reception rooms meant to make it a social center. Early criticism of its warlike facade nearly forced a redesign, but the commanding general backed it. It later served as home of the 250th Coast Artillery and hosted boxing matches. It is the largest historically and architecturally important building in the Mission District, and its exterior remains as designed.","period_of_significance":"1900- (specific dates: started September 1912, completed June 1914)","architect_builder":"Architects: Woollett & Woollett; Builder: McLeran & Peterson","architectural_style":"Spanish-style fortress with Moorish influence, combined with a Machine Age barrel-vaulted gymnasium/auditorium","criteria":[],"status_note":"Form lists condition as excellent, with exterior and first floor unaltered; upper floors extensively remodeled; auditorium has a wood roof instead of the intended glass.
