Hocus Pocus Hall was a themed walk-through attraction at Chessington World of Adventures Resort in southwest London, England.
In the English Civil War it became a royalist stronghold, later being razed by Oliver Cromwell's Parliamentary forces giving it its modern name.
[2] During the park's 2013 Halloween event, the attraction had a makeover as “The Mystery of Hocus Pocus Hall”, featuring a new theme overlay and soundtrack.
It was announced in October 2018 that Hocus Pocus Hall would be redeveloped as Room On The Broom, based on the children's book by Julia Donaldson.
After the tunnel, you reached a laboratory where goblins were causing chaos in the form of animated figures and peppers-ghost style video screens.
