This week on All Around Britain Alex Beresford and Ria Hebden get in the Halloween spirit as they go underground in Edinburgh.
The Blair Street Vaults are a series of chambers and rooms beneath Edinburgh’s South Bridge, which was built in the 18th century.
Shops and taverns used the underground spaces to trade, until the damp and dimly lit conditions forced them to move out.
The vaults soon became an overcrowded, filthy, disease ridden slum and stories say that illegal taverns, distilleries, brothels and drug dens took over the vaults and it became a playground for criminals, murderers, thieves and even body snatchers.
In the 1860s, the vaults were filled with rubble and stone and permanently closed. It wasn’t until the 1980s that they were rediscovered and excavated.
Since reopening they have been taken over by Mercat Tours and there have been a number of claims of ghost sightings and strange noises from the rooms underneath Edinburgh.
The vaults are said to be Edinburgh’s most haunted site and have been visited by world renowned paranormal investigators.
Alex and Ria put on a brave face and went to find out more.
