From the plague to the great fire of London to the Battle of Waterloo through the London Dungeon, Jack the Ripper and all the weird things the Victorians got up to, we'll be channelling Sweeney Todd, Bedlam, the Krays, Barbara Windsor, The Lizard Queen Elizabeth II and asking, is Paul McCartney really dead? And for a dose of 21st Century horror let's not forget Farage's Plane Crash, Brexit and the legacy of Margaret Thatcher.
If it's British and it can die or kill you then it's on the menu.
As usual we'll be giving £100 in cold hard cash to the person with the best costume and a £50 bar tab to the runner up.
Dress to impress and get in free with your costume.
Free tickets are available until 10.45pm and valid for entry before 12.
Presented by White Heat.
