Beneath the South Bridge — one of Edinburgh's busiest streets — lies a network of sealed chambers that were forgotten for nearly two centuries. Rediscovered in 1985, the South Bridge Vaults have since become one of the most compelling — and most haunted — sites in Scotland. Here's what they are, how they were built, and what awaits you underground.
The South Bridge Vaults are a series of chambers built into the arches of the South Bridge, which was completed in 1788. The bridge spans the Cowgate valley — but because the surrounding buildings are so tall, from street level it doesn't look like a bridge at all. Beneath the road surface, nineteen arches support the structure, and within those arches, small chambers were created and leased out as workshops and storage spaces.
They were abandoned surprisingly quickly. The bridge's construction was rushed, and the stonework was porous. Within a decade of completion, damp had made the chambers uninhabitable. By the early 1800s the vaults had been sealed and forgotten. Edinburgh kept building on top of them. For nearly 200 years, they sat in darkness beneath the city.
When the vaults were originally in use, they housed cobblers, smiths, and traders — ordinary workers who needed cheap workshop space. As conditions deteriorated and the chambers flooded with damp, these legitimate tenants moved out. What moved in was a different sort of Edinburgh entirely.
Historical records and archaeological evidence suggest that the lower vaults, furthest from daylight and ventilation, became home to some of the city's most desperate residents — the urban poor who had nowhere else to go. Illicit trade, illegal distilleries, and worse allegedly operated in the deeper chambers. Some accounts claim the vaults were used by body snatchers as temporary storage before delivering corpses to the anatomy schools on Surgeons' Square — though documentation for this is contested.
The vaults are said to be among the most haunted sites in a city that takes its hauntings seriously. Paranormal investigators have conducted studies here, and the accounts are unusually consistent. The most frequently reported presence is Mr Boots — named for the heavy footstep sounds that visitors hear — and a child known as Jack who is said to be attached to a small chamber in the lower vaults.
Whether you believe in such things or not, there's something undeniably affecting about standing in a sealed stone chamber thirty feet below a busy 21st-century street, surrounded by the same walls that Edinburgh's forgotten inhabitants pressed themselves against two centuries ago.
Tours descend through a ground-level entrance on Blair Street, just off the Cowgate. The chambers are unlit beyond guide torches, and the temperature drops noticeably below street level. Expect narrow passages, low ceilings in some chambers, and uneven stone floors. The whole experience is genuinely atmospheric without relying on theatrical tricks.
Good vault tours separate documented history from folklore — explaining what the archaeology and records actually show, while also engaging with the stories that have accumulated around the place. The best guides understand that the real history is more disturbing than the ghost stories.
Our two-hour Old Town Underground tour explores the South Bridge Vaults alongside the network of streets and closes that run below street level through Edinburgh's Old Town. The focus is on social history — who lived and worked down here, what drove them underground, and how the city above them developed while they were forgotten.
We cover Burke and Hare, the anatomy trade, the Cowgate slums, and the vaults themselves — with particular attention to what the physical evidence actually tells us versus what later writers invented. History as it was lived tends to be darker than the tourist version, and more human.
Two hours beneath Edinburgh's streets. The vaults, the closes, the history the city built over and forgot.
