In 2006, a Columbia University finance PhD graduate named Peter Acworth purchased a 200,000 square foot reproduction of a Moorish castle. The castle has gained notoriety over the years before he purchased it as a National Guard office and film set for various sequences in the Star Wars movies. More recently, Groupon has been offering tours of the replica castle, and it has been the source of some controversy.

Currently the armory is being used as the Kink.com porn studios. The castle has served as the shooting grounds for many bondage films since being acquired by Acworth in 2006. Located in San Francisco, the Groupon-offered walking tour of the facilities has become quite popular, but anti-porn activists, Morality-in-Media, would like to see Groupon stop offering the deal and stop promoting the studio.

Check out this video from the executive director of Morality in Media as she gives some details about what they do and a recent effort to stop pornography on a Delta Airways flight:

For $28 two adults, who must be over 18 years-of-age, can tour the 200,000 square foot castle and Kink.Com movie sets. What the studio offers is an unbelievable opportunity to see a live shooting of an adult bondage film. The tour is 40 minutes long and expires this coming January.
