The room was located in the Hart family mansion basement and had a very low ceiling. For most of the duration of the room being used as training hall there was a wrestling mat located on the floor without any ropes which would be used for training students.
History
Hart acquired the former army hospital mansion in 1951 and transformed its basement into his personal training centre shortly thereafter. This was done because Hart needed a training facility after the founding of his first wrestling promotion in 1948. Although, the nickname itself developed over time when Stampede Wrestling became world famous. Aside from professional wrestlers, the Dungeon provided training grounds for various athletes from strongmen to football players. The majority of Hart's sons trained in the Dungeon and went on to become involved in the wrestling world including Bret and Owen Hart. Other famous Dungeon graduates include Billy Graham, Greg Valentine, Allen Coage, Davey Boy Smith, Brian Pillman, Jushin Thunder Liger, Ricky Fuji, Chris Jericho, Lance Storm, Chris Benoit, Justin Credible, Edge, Christian and Mark Henry. Natalya, daughter of Jim Neidhart and granddaughter of Stu, was the first ever woman to graduate from the Dungeon. One of the first televised acknowledgements of the nickname "Dungeon" was by then WWFcolor commentatorJesse Ventura. Its first significant exposure was in the documentary . In it, the Dungeon was moderately filmed for the first time and Stu Hart is shown demonstrating wrestling holds on a pupil. Bret also discusses being trained by his father and having submission holds applied to himself, often with graphic descriptions from his father of the holds' impact. A bonus feature on also shows him discussing the Dungeon. Various activities took place in the Dungeon, ranging from weight lifting to Catch wrestling. Bret Hart has described the Dungeon in interviews as having holes in the walls and ceiling from bodies being driven into them. He also noted that practices could, at times, be as intense as MMA styled fighting. In July 1998, the WWF filmed a match between Owen Hart and Ken Shamrock in the Dungeon for the pay-per-view.
Reputation
During the period when Stu Hart was regularly training individuals at the school, it held a reputation for being one of the harshest wrestling schools in the world. Graduating from it was considered very impressive and something which would be brought up on air on televised wrestling shows. Hart himself also garnered a reputation for being borderline sadistic in his training techniques, and was known to torture his pupils with legitimate submission wrestling holds he had learned as a sports wrestler. Buddy Roberts described the place as "like a torture chamber". In contrast to his descendants, Stu never took money for his training services and did it mostly for the love of the artform of professional wrestling.
In modern day being trained in the Dungeon carries a level of status and there have been many attempts to recreate and recapture its glory. In 2005 a documentary directed by Blake Norton named was released.
Subsequent training camps run by members of the Hart family
After their father's retirement some of the Hart brothers managed the school by themselves under the name Hart Brothers Training Camp which was also known by the nickname School of Hart Knocks. Leading up to the Hart House's sale in 2003, the Hart Brothers Training Camp run by Bruce, Keith and Ross was still running three times a week in the basement of the Hart mansion. A very similar training camp remains today at the family's gym, although none of the Hart brothers are involved. Teddy Hart, Stu Hart's oldest grandson ran a training camp in Texas named Texas Hart Dungeon from around 2012 to 2015. Smith Hart, Stu's oldest son founded a new wrestling school in 2015 named Dungeon Discipline Professional Wrestling School which is run out of Calgary and Berrie in Alberta, after Smiths passing in 2017 the training is mostly handled by Smith's son Matthew.
