The chamber closed on 11 April 2016 and has since been replaced by a new attraction named the Sherlock Holmes Experience. Visiting the exhibit was optional and not recommended for young children or pregnant women. Figures of disgraced entertainers Jimmy Savile and Gary Glitter were destroyed rather than being relocated to the Chamber of Horrors. There was no waxwork figure of Jack the Ripper in the Chamber of Horrors, in accordance with Madame Tussaud's policy of not modelling persons whose likeness is unknown. Historical characters displayed included Vlad the Impaler, Genghis Khan, Guy Fawkes and Adolf Hitler. An innovation in recent years was to have actors in macabre make-up and costumes lurch at customers from the dark shadows and recesses of prison cells, where some cells were occupied with waxwork figures and others had the doors ajar, giving the impression that a dangerous maniac was on the loose.

The Chamber of Horrors was renovated in 1996 at a cost of $1.5 million, bringing to life the history of crime and punishment over the last 500 years and including items from Newgate Prison and featuring replicas of instruments of torture displayed amid a recording of actors' groans and screams. This part of the exhibition was in the basement of the building and included wax heads made from the death masks of victims of the French Revolution including Marat, Robespierre, King Louis XVI and Marie Antoinette, who were modelled by Marie Tussaud herself at the time of their deaths or execution, and more recent figures of murderers and other notorious criminals. Other exhibits have included George Chapman, John Reginald Halliday Christie, William Corder, Dr Hawley Harvey Crippen, Colonel Despard, John Haigh, Neville Heath, Bruno Hauptmann, Henri Landru, Charles Manson, Florence Maybrick, Donald Neilson, Dennis Nilsen, Mary Pearcey, Herbert Rowse Armstrong, Buck Ruxton, George Joseph Smith and Arthur Thistlewood. In 1886, the exhibits included Burke and Hare, James Bloomfield Rush, Charles Peace, William Marwood, Percy Lefroy Mapleton, Mary Ann Cotton, Israel Lipski, Franz Muller, William Palmer and Marie Manning. Visitors were charged an extra sixpence to enter the 'Separate Room'. The name 'Chamber of Horrors' is often credited to a contributor to Punch in 1845, but Marie Tussaud appears to have originated it herself, using it in advertising as early as 1843. At this time, her exhibits included Colonel Despard, Arthur Thistlewood, William Corder and Burke and Hare, in addition to those listed above.

In 1835, Madame Tussaud set up a permanent exhibition in London, and here the 'Separate Room' became the 'Chamber of Horrors'.

The exhibits at this time included the heads of King Louis XVI and Marie Antoinette, as well as Madame du Barry, Marat, Robespierre, Hébert, Carrier and Fouquier-Tinville in addition to models of a guillotine and the Bastille and the Egyptian mummy from Curtius' collection.ġ877 in London with a man putting up an advertisement for the Chamber of Horrors When Marie Tussaud moved to London in 1802 to set up her own exhibition at the Lyceum Theatre she brought some of these figures with her and set them up in a separate gallery and when later she toured her exhibits around the country she maintained this division in her exhibition using a 'Separate Room' to display them in. Here Curtius displayed wax figures of notorious French criminals who had been executed, as well as members of the French royal family and aristocracy who had been guillotined during the Revolution. The forerunner of Tussaud's Chamber of Horrors was the Caverne des Grands Voleurs (the Cavern of the Great Thieves) which had been founded by Dr Philippe Curtius as an adjunct to his main exhibition of waxworks in Paris in 1782.
