Officially known as the San Francisco National Guard Armory and Arsenal, the Armory is a 200,000 sq ft Moorish Revival castle at Mission and 14th. Built in 1914 by the architectural firm Woollett and Woollett as a replacement for the original armory destroyed in the 1906 Earthquake, it was used by the National Guard between 1914 and 1976. After sitting empty for thirty years it was purchased by Kink.com in 2007. The building exterior features four octagonal towers, rough brick exterior walls, and narrow lancet windows. Inside, the space is divided into two sections -the 84,700 sq. ft. Administration Building and the 39,000 sq. ft. Drill Court - and features offices, a gymnasium, swimming pool, locker and dressing rooms, an industrial kitchen, a banquet room, arsenal, company store room, boiler room, and indoor rifle range.
