The Crystal Maze was one of the ambitious and most popular programmes produced by Channel 4. The show was at the time the most watched on Channel 4, attracting up to 6 million viewers at its height and The Crystal Maze is considered by some to be, "a highly-ambitious, high-risk show that paid off handsomely." The maze cost £250,000 to build and was the size of two football pitches. 6 Moving from the final Zone to the Dome.Originally, Chatsworth Television intended to make a British version of the French show Fort Boyard, but when it became clear that the fort would not be available at the time of the pilot show, Fort Boyard's creator Jacques Antoine was consulted about developing an alternative format that could be shot elsewhere. As a result, the show ended up using a concept similar to Fort Boyard, but was substantially different in presentation and style. It was filmed on a very large set, originally at H Stage in Shepperton Studios, but in later series at an adapted aircraft hangar named Aces High Studios, at North Weald Airfield in Essex. A UK version of Fort Boyard was eventually made by Channel 5, long after Channel 4 ended The Crystal Maze. The set was divided into four 'Zones' set in different periods of time and space.
