Hell in a Cell is a professional wrestling cage-based match which originated in 1997 in the World Wrestling Federation (WWF, now WWE). It features a large cell structure, a five-sided cuboid made from open-weave steel mesh chain-link fencing which encloses the ring and ringside area. Unlike the steel cage match, the only way to get out of the Hell in a Cell without damaging the Cell's structure is through an integrated door, which is part of the Cell and is locked by chains and a padlock. Only an in-ring pinfall or submission will ordinarily result in a win (although Triple H pinned Chris Jericho atop the cell to win the Hell in a Cell match at Judgment Day in May 2002) and there are no disqualifications.
