The Hidden Vaults Beneath Edinburgh’s Royal Mile

Sharing is caring!

In 1985, a man named Norrie Rowan was exploring below Blair Street in Edinburgh’s Old Town when he pushed open a long-sealed door. On the other side was a network of stone chambers that had sat in complete darkness for over 150 years. No one had been inside since the mid-1800s. What he found was the Edinburgh Vaults — one of Scotland’s most remarkable hidden spaces, buried beneath one of the city’s busiest streets.

Today, thousands of visitors walk above these chambers every year without knowing they exist. But if you know where to look — and book the right tour — you can step below the Royal Mile and into a world that time forgot.

How the South Bridge Was Built — and What It Hid

The South Bridge was completed in 1788. It spans the Cowgate valley, connecting the Old Town to the university district to the south. It was an ambitious piece of engineering for its time — a bridge with 19 arches. But here is the strange part: you cannot see 18 of those arches from street level. The buildings on either side of the bridge were constructed directly against its walls, enclosing the arches and turning them into chambers.

These enclosed spaces became the Edinburgh Vaults. In the early years, tradespeople moved in. Cobblers, tailors, wine merchants and other businesses set up in the stone chambers. There were even taverns operating below street level. The vaults were damp and poorly ventilated, but they were usable — and space in the Old Town was scarce.

Within a few decades, that changed. The Cowgate below flooded periodically. Moisture seeped through the stone. The air turned foul. By around 1820, the conditions had become too grim for most tenants. Businesses moved out. The poorest residents of Edinburgh moved in — the homeless, the destitute, those with nowhere else to go. Eventually, even they were gone. The entrances were sealed, the vaults forgotten, and the city above carried on as if they had never existed.

The Rediscovery in 1985

For roughly 150 years, the vaults sat in total darkness. No maintenance. No visitors. Just sealed stone rooms beneath a working city.

Norrie Rowan changed that in 1985. He had heard rumours of underground spaces below the South Bridge and decided to investigate. When he found his way in and began exploring with a torch, he discovered the chambers largely intact. Artefacts remained from the last occupants. The structure, while deteriorated in places, was still standing.

The discovery was significant enough to attract wider attention. Archaeologists and historians began documenting what was inside. In the early 1990s, guided tours were introduced, making the vaults accessible to the public for the first time. What had been a forgotten relic of Georgian Edinburgh was now one of the city’s most talked-about attractions.

What You’ll Actually Find Inside

The vaults run beneath Blair Street and South Bridge, forming a series of connected chambers at different levels. The ceilings are low — stone arches that curve overhead in the darkness. The walls are rough-cut and damp. In places, the floor is original cobblestone.

Several of the chambers are large enough to stand and move around in. Others are tighter, requiring visitors to duck through low doorways. The layout is maze-like, and without a guide, it would be easy to get turned around.

Some of the rooms show clear evidence of past habitation — remnants of fireplaces, evidence of old floor surfaces, the shapes of where furniture once stood. Archaeologists have found animal bones, pottery fragments, shoes and other objects from the 18th and early 19th centuries. The vaults give a direct physical connection to the everyday lives of people who lived in Edinburgh during that period — not the wealthy residents, but the tradespeople and poor who occupied the margins.

One chamber has been identified as a likely plague vault — a place where victims of disease were confined during earlier outbreaks. Whether this specific identification is accurate is debated by historians, but the city’s history of plague and overcrowding is well documented.

The Paranormal Reputation

The Edinburgh Vaults have developed a strong reputation as one of the most haunted places in Scotland — and the claims are taken seriously enough that several scientific investigations have been carried out there.

In 2001, Dr Richard Wiseman of the University of Hertfordshire conducted a study in the vaults as part of a wider investigation into haunted locations. Volunteers who entered the vaults — without being told anything about its history — reported unusual experiences at statistically significant rates. Feelings of sudden cold, physical discomfort, visual disturbances and a strong sense of presence were among the most common reports.

Wiseman’s conclusion was cautious: the vaults produce measurable psychological effects on visitors, but whether those effects are caused by the paranormal or by environmental factors — air movement, uneven surfaces, low light, infrasound — could not be determined. The study was one of the most rigorous ever conducted in a location with a haunted reputation.

Tour operators have built on this reputation, and several companies now offer night tours specifically focused on the paranormal angle. These tours have a different character from the daytime history tours — smaller groups, less light, and a more theatrical approach to the storytelling. Whether you believe in ghosts or not, being in the vaults at night is an experience that most visitors find memorable.

The People Who Lived Here

It is easy to think of the vaults primarily as a tourist attraction or a ghost story location. But the more historically interesting question is who actually lived and worked here, and under what conditions.

Edinburgh in the late 18th and early 19th centuries was one of the most overcrowded cities in Britain. The Old Town, built on a narrow ridge, had expanded vertically rather than outward. Tenement buildings reached ten or twelve storeys. The closes — narrow alleys running down from the Royal Mile — were packed with people at every level of society. The very wealthy and the very poor shared the same buildings, separated only by which floor they could afford.

The vaults were part of this overcrowded world. They represented the lowest rung — literally underground, without natural light, without ventilation, in near-constant damp. The people who ended up there were not just poor; they were people who had run out of other options. Understanding the vaults properly means understanding that they were not a curiosity but a lived reality for a significant number of Edinburgh residents.

That context makes a tour of the vaults considerably more interesting than a simple ghost story ever could.

How to Visit the Edinburgh Vaults

The vaults are not accessible independently — you must book a guided tour. Several well-established companies operate tours, including Mercat Tours and Auld Reekie Tours, both of which have been running for decades. Tours depart from various points near the South Bridge, usually from around 10am through to late evening.

Daytime tours focus primarily on the history and archaeology of the site. Evening and night tours lean into the ghost stories and paranormal angle. Prices typically range from £15 to £20 per adult, and booking in advance is recommended, particularly during summer when Edinburgh fills up quickly.

A few practical points worth noting: the vaults are cold year-round, regardless of the weather above. Wear an extra layer even in summer. The passages are uneven and sometimes narrow — sensible footwear matters. Some sections involve low doorways or steps without handrails. Operators note any significant mobility limitations on their booking pages, and most will advise if certain sections are not suitable.

Tours typically last between 60 and 90 minutes. If you are visiting Edinburgh for more than a day or two, it is worth combining a vaults tour with a visit to the Real Mary King’s Close — another underground site nearby, with a different but equally compelling history. Between the two, you get a thorough picture of what Edinburgh’s underworld — in the literal sense — actually looked like.

Getting There

The South Bridge Vaults are located in central Edinburgh, a short walk from the Royal Mile and Waverley Station. Tour meeting points vary by operator but are typically on or near the South Bridge itself. From Waverley, it is roughly a 10-minute walk uphill to the Old Town. From Edinburgh Waverley station, head up Waverley Bridge and follow the Royal Mile west — the South Bridge junction is clearly signed.

Parking in this part of the city is limited and expensive. Edinburgh’s city centre is most easily reached by train or bus. If you are driving from further afield, the Edinburgh Park and Ride services offer a more practical option than trying to park in the Old Town.
