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.
Two significant architectural facts about the Armory: you can see a small portion of Mission Creek from the basement and the Drill Court is the largest unsupported enclosed space in San Francisco.
Two significant cultural facts about the Armory: In 1976, George Lucas used the Drill Court to film some scenes for Star Wars and for almost thirty years, boxing prizefights were held in the Drill Court each Tuesday and Friday night earning the building the nickname "The Madison Square Garden of the West".
The Armory was nominated to the National Register in 1978 for three areas of significance: architecture, engineering and military; for the period of significance 1900-1912.
In March of 2014, Kink.com and the building's owner submitted a plan to the Planning Department to convert the building's porn production facilities into office space. This move is said to be spurred by CA Assembly Bill 1576, which makes it illegal to shoot porn in California without the use of condoms.
