The Edinburgh Vaults are said to be the most haunted location in Scotland, and are by far the most haunted underground location in the UK.

The vaults were built to cope with the Scottish city's growing population, and were used to house taverns, workshops for cobblers and other tradesmen, as well as storage space for these merchants.

Conditions soon became grim in the vaults, business shut shop and left, leaving the vaults in the hands of the poor, the homeless and criminals. The chambers became so notorious for illegal activities that they were eventually filled in, only to be unearthed years later and turned into the tourist attraction it is today.
