The SF Armory, aka the former 'Kink Castle', may return as concert/event venue with added jazz club

From ammunition depot to sports venue to giant porn production house, the San Francisco Armory has gone through several iterations in its 109-year history, and may soon be slated to return as an active event space. Listed on the National Register of Historic Places, there are new plans to turn a portion of the innards of the giant, castle-like Armory in the Mission District into a jazz club and VIP lounge.
