San Francisco Armory
The San Francisco Armory, also known as the San Francisco National Guard Armory and Arsenal or simply The Armory, is a historic building in the Mission District of San Francisco, California.

National Guard Armory
The building was constructed as an armory and arsenal for the United States National Guard in 1912–1914 and designed with a castle-like appearance in a Moorish Revival style. The structure was built as a replacement for the old San Francisco Armory in the Western Addition, which had been destroyed by the 1906 earthquake. In addition to its role as an armory and arsenal, during the 1920s, it served as a venue for sporting events, such as prizefights. The Armory served as a stronghold and rallying point for the National Guard in their suppression of the 1934 San Francisco General Strike (an event known as "Bloody Thursday"). The building closed as an armory in 1976, when the National Guard moved its facilities to Fort Funston.

1976–2006
After 1976, the building was largely unused for the next 30 years, though in 1978 the building was registered as a Class 2 historical landmark in the National Register of Historic Places. Several spaceship-interior scenes in the movie Star Wars were filmed there, and the San Francisco Opera used the large inner court of The Armory for set construction and rehearsals until the mid-1990s. By this time, The Armory was in a heavy state of disrepair. Various uses of the building were proposed from 1996–2006, including self storage units, a rehabilitation clinic, a gym with a rock wall, a dot-com office park, a telecommunications switching center, luxury housing, and low-income housing. Many of these proposals were marked by acrimonious debates between various community interests. Concerns over gentrification, social and environmental impact or the unsuitability of the structure for various uses resulted in none of the various plans for the structure reaching fruition. The building eventually came to be described, variously, as "a herd of white elephants", "cursed", and "not a friendly building".

Kink.com purchase
In late 2006, The Armory was purchased for $14.5 million by Kink.com, a San Francisco-based internet pornography producer specializing in BDSM pornography. As of 2007, the company is using the building as a studio for production of content for their websites. Peter Acworth, the company's owner, has stated that the structure suits the needs of the company very well without need for significant structural modifications to the building, and that the company would begin repairs to the decaying structure. It was also announced that Kink.com planned at some point in the future to rent out studio space for film production of all kinds within The Armory. The sale was not announced until January 2007 as a result of a non-disclosure agreement with the previous owner. The sale drew a mixed response from the San Francisco community. Many people welcomed this use of The Armory as a way of revitalizing the structure and bringing back business to the area without altering the appearance of the historic building, as well as being in keeping with San Francisco's tradition of accommodating sexual minorities. Others were disturbed that a pornography studio would be located in the middle of a residential neighborhood near schools, or were opposed to the abandonment of plans for low-income housing at the site, as well as the lack of community input into this use of The Armory. A group known as the Mission Armory Community Collective soon formed in opposition to Kink.com's use of The Armory; the group held a public protest in front of The Armory in early February 2007. San Francisco mayor Gavin Newsom also expressed concern over the Kink.com purchase, and scheduled a special meeting of the San Francisco Planning Commission in March 2007 to review the company's use of the building. This public meeting was well-attended by both supporters and detractors of the Kink.com purchase. The Planning Commission for its part ruled that Kink.com was not in violation of any law or zoning requirement. Although Kink.com has stated that its activities would be invisible to the surrounding neighborhood, La Casa de las Madres, a neighboring women's shelter, announced in late March 2007 that they would be leaving the location. The shelter had planned on moving from that location in 2009 when their lease expired, but stated that they would be leaving early because of Kink.com's presence. In late 2007, Acworth approached the San Francisco Planning Commission with the idea of converting part of the Armory space into webcam-lined condominiums. However, Acworth also described the plans as "extremely hypothetical" and stated that, "There is no firm plan for using the Armory for anything but a conventional film studio for now." In May and December, 2008, the San Francisco Armory hosted Mission Bazaar, an all-ages arts fair featuring local artists and craftspeople selling their work, as well as performances. It was the first public event held in the Armory since the 1970s. A creek runs through the basement of the Armory. Mission Creek once flowed through San Francisco, but like many other creeks in the city, it was diverted into the sewer system in the 1800s. The Armory's basement is the only place where Mission Creek can still be seen.
