This major tourist attraction is housed under some of the existing arches of the London and Greenwich Railway line. There is very little actually written history of the building as it is today but it is has previously been used as a stable block, wine cellar and possibly an orphanage. From 1212 The Hospital of St. Thomas The Martyr stood on the site of the dungeon. It was run by a mixed order of nuns and monks and provided shelter and treatment for the poor, sick and homeless. During WWII the railway arches were used as air raid shelters but were themselves bombed in February 1941. It is believed that the bodies of many of the victims were never recovered and that they remain entombed in the arches to this day. Shadowy figures have been seen throughout the dungeon, while a male figure dressed all in black is thought to have an evil, negative presence. A member of staff has apparently seen a group of children playing ring-a-ring-o-roses, while in the 'Pre-Plague' area a man and two children are regularly seen who mysteriously disappear upon approach. The naked top half of a man has been seen apparently floating in the 'London Bridge' area, while a phantom man has been seen standing between the waxworks of two men operating on a body in the 'Mortuary' area.
