Exeter's Underground Passages: The Hidden Tunnels Beneath the City

Beneath the Pavements, Another City

Walk along Exeter's High Street on a busy Saturday and you are passing directly above a network of medieval tunnels that most people have no idea exist. Built in the fourteenth century to solve a practical problem — bringing clean drinking water into the walled city — Exeter's Underground Passages are the only publicly accessible medieval passages of their kind in Britain. They are strange, atmospheric, and genuinely unlike anything else you can visit in the country.

The passages are not grand. They are not cavernous. In places, you will need to duck. But that is precisely what makes them extraordinary. These are not tourist constructions or heritage recreations. They are the real thing — narrow, stone-lined tunnels carved beneath a living city more than six hundred years ago, preserved almost exactly as they were when medieval engineers crawled through them to maintain the lead pipes that supplied Exeter's water.

If you have ever felt that Exeter's history is something you only experience through plaques and museum displays, the Underground Passages will change your mind. Down here, you are inside the history. You can touch it. You can feel the temperature drop. And you can imagine, very vividly, what it was like to be the person whose job it was to wriggle through these tunnels by candlelight to fix a leaking pipe.

The History: Why Build Tunnels for Water?

The story of the passages begins in the thirteenth century, when Exeter's growing population faced a fundamental problem. The city was enclosed within its Roman and medieval walls — impressive for defence, but inconvenient for water supply. The natural springs that provided clean drinking water lay outside the walls, and bringing water into the city required a system of lead pipes.

The earliest passages date to around 1346, when the Cathedral Chapter built a tunnel to house the lead pipes carrying water from springs to the north-east of the city into the Cathedral Close. The city authorities followed suit, constructing additional passages to supply public conduits — communal water fountains — in the High Street and other central locations.

The reason for building tunnels rather than simply burying the pipes was practical. Lead pipes leak, crack, and need regular maintenance. If the pipes were buried directly in the ground, every repair would require digging up the street — an expensive and disruptive process. By housing the pipes in accessible passages, engineers could inspect and repair the water system without disturbing the surface above. It was an elegant solution to a mundane problem, and it is this very pragmatism that preserved the passages for us to explore today.

The water supply system remained in use for centuries, with the passages maintained and extended over time. It was not until the nineteenth century, when modern iron pipes and a municipal water system replaced the medieval infrastructure, that the passages fell out of regular use. By then, most people had forgotten they existed.

Visiting the Underground Passages

The Experience

A visit to the Underground Passages begins in the interpretation centre, located beneath the entrance on Paris Street. The centre is packed with interactive displays that explain the history of the passages, how the water system worked, and what life was like in medieval Exeter. It is well designed and engaging — particularly good for older children and anyone who likes to understand the context before diving in.

The guided tour itself takes you underground into the passages. Tours are led by knowledgeable guides who bring the history to life with stories and explanations as you navigate the narrow tunnels. The passages are constricted and low in places — this is not a walk through spacious caverns — and the experience is genuinely atmospheric. The temperature drops, the light dims, and you become very aware that you are walking beneath a busy modern city through tunnels built six hundred years ago.

Tours generally start half an hour after opening and run at regular intervals throughout the day. Each tour lasts approximately twenty-five minutes underground, plus time in the interpretation centre. The entire visit typically takes around forty-five minutes to an hour.

Practical Information

Opening hours: Thursday to Sunday, 11:00am to 4:00pm, with the last tour starting at 3:00pm. Hours may vary seasonally, so check the Exeter City Council website before visiting.

Admission prices: Adults £7.50, children £5.00, concessions £6.00, family ticket (two adults and up to three children) £22.00.

Booking: Online booking is available through the Exeter Corn Exchange website and is strongly recommended. The attraction gets extremely busy during weekends and school holidays, and tours can sell out — maximum tour size is 15 people, so spaces go quickly. Walk-ups are accepted when space is available, but you may face a wait. You can also email [email protected] with your preferred day, time, and party size.

Location: The entrance is on Paris Street within the Princesshay Quarter — look for the signs near the pedestrian area. It's a two-minute walk from the High Street.

Important restrictions: Children under five are not permitted on the underground tours, though they can access the exhibition for free with an accompanying adult. The passages are not suitable for anyone who suffers from claustrophobia — the tunnels are genuinely narrow and low in places. Wheelchair and pushchair access is limited to the interpretation centre only; the underground passages are not accessible.

Hidden Exeter: More History Worth Discovering

The Underground Passages are the most dramatic example of Exeter's hidden history, but they are far from the only one. The city is full of historic buildings and spaces that most people walk past without realising what they are. Here are some of the best.

The Guildhall

Exeter's Guildhall, on the High Street, has been claimed to be the oldest municipal building in England still in regular use. There has been a guild hall on this site since at least AD 1000, though the current building dates primarily from 1468 to 1470.

Step inside and you enter a medieval great hall with an arch-braced roof of seven bays, its main trusses resting on carved corbels in the shape of grotesque animals. The elaborately carved oak door at the entrance was made in 1593 by Nicholas Baggett, a local carpenter. The hall has witnessed some remarkable moments in English history — most notoriously, Judge Jeffreys held the Bloody Assizes here in September 1685, sentencing supporters of the failed Monmouth Rebellion.

The Guildhall is still used for civic purposes: official receptions, mayoral banquets, council meetings, and occasionally as a magistrates' court. It is sometimes open to visitors — check with the city council for current opening times. Walking into a building that has served its original civic function continuously for over five hundred years is a quietly remarkable experience.

Tucker's Hall

Tucked away on Fore Street, Tucker's Hall is one of Exeter's most overlooked historic buildings. Built in 1471, it is the guild hall of the Incorporation of Weavers, Fullers and Shearmen — the trade guild that controlled Exeter's once-mighty woollen cloth industry.

The name comes from the "tuckers" — the fullers who cleaned and thickened woven cloth by beating it. At its peak, Exeter was one of the most important cloth-producing cities in England, and the wealth generated by the wool trade paid for many of the city's finest buildings, including much of the Cathedral.

Tucker's Hall has a remarkable interior, with a fine timber roof and carved wooden screen. The Incorporation received its Royal Charter in 1620 and continues to meet in the hall today — one of the longest-running trade guilds in the country. The hall has served various purposes over the centuries, including as a school from 1675 to 1841 and as a Freemasons' lodge from 1842 to 1875.

Tucker's Hall opens to visitors on selected days — typically Tuesday to Friday during the summer months. Opening times are limited, so check before visiting. It is a small building and easy to miss from the street, but the interior is well worth seeing if you can time your visit right.

The Custom House on Exeter Quay

Down on Exeter Quay, the Custom House is another building that most people admire from the outside without realising its significance. Built in 1680-81 by Richard Allen, a bricklayer from Bideford, it is believed to be the first purpose-built custom house in England and the oldest brick building in Exeter.

The building was constructed in response to the booming trade at Exeter Quay, particularly in woollen cloth. Its most celebrated feature is the moulded lime plaster ceilings on the first floor, created by John Abbott of Frithelstock in North Devon. The building must have seemed astonishingly modern when it was completed — a fashionable brick structure in a city still dominated by timber-framed buildings.

The Custom House operated as an active HM Customs facility until 1989. Today, it serves as a visitor centre with free admission, housing models and artefacts from the cloth trade alongside an immersive audiovisual presentation covering two thousand years of Exeter's history. It is also the meeting point for the Red Coat Guided Tours of the Quayside.

Why Hidden Places Bring People Together

There is something about discovering a hidden place that naturally creates connection. When you emerge from the Underground Passages blinking into the daylight, or step into the medieval gloom of Tucker's Hall, or learn that the oldest municipal building in England is sitting in plain sight on the High Street — these are the moments that make you want to turn to the person beside you and say, "Can you believe this is here?"

Shared discovery is one of the most powerful social bonding experiences there is. It creates conversation, generates shared memories, and gives people something to talk about long after the visit is over. Exeter is full of these moments — places that reward curiosity and exploration, that reveal themselves gradually, and that feel more special because you had to seek them out.

This is one of the things we love about living in Exeter, and it's why we wrote an entire walking tour of the city's hidden gems. The city does not shout about its history. It does not have the tourist infrastructure of Bath or the global profile of York. But for those who look carefully, who wander down side streets, who ask questions and follow their curiosity, Exeter reveals a depth of history and character that is genuinely extraordinary.

The Underground Passages are the perfect example. They are literally beneath the surface — hidden, unexpected, and far more interesting than you would imagine. A bit like the best friendships, really. The ones worth having are rarely the ones that are immediately obvious. They are the ones you discover when you are willing to go a little deeper.

The Passages Through the Centuries

The Underground Passages have had a more eventful life than you might expect from a set of water tunnels. During the English Civil War, when Exeter was besieged by Parliamentary forces in 1646, there were genuine fears that the besiegers might use the passages to gain access to the walled city. The entrances were blocked and guarded. In the Second World War, parts of the passage network were considered for use as air raid shelters during the Exeter Blitz, though the narrow dimensions made them impractical for large numbers.

The passages were rediscovered as a visitor attraction in the 1930s and have been drawing the curious underground ever since. They survived the Blitz intact — the bombs fell above them, but the medieval stonework held. Today, the interpretation centre that greets you before you descend includes interactive displays on medieval water engineering, a timeline of the passages' history, and a surprisingly engaging section on the geology of the red Heavitree sandstone through which much of the tunnelling was carved.

For families, the passages are one of the best rainy day activities in Exeter — atmospheric, educational, and genuinely exciting for older children. Combine them with a visit to the free galleries at RAMM and you have a full morning of discovery without spending more than a few pounds.

Planning Your Visit

If you want to combine several of Exeter's hidden historic sites into a single day, here is a suggested route.

Morning: Start at the Underground Passages on Paris Street. Book the first tour of the day for the quietest experience. Allow forty-five minutes to an hour for the full visit including the interpretation centre.

Late morning: Walk to the Guildhall on the High Street — it is less than five minutes away. If it is open, step inside. If not, admire the Elizabethan frontage and the carved oak door.

Lunchtime: Head down Fore Street to Tucker's Hall. Check opening times in advance. From Tucker's Hall, continue downhill towards Exeter Quay for lunch at one of the Quayside restaurants or pubs.

Afternoon: Visit the Custom House Visitor Centre on the Quay (free admission), then walk along the canal towpath or explore the independent shops in the Quay area.

Evening: Walk back up to Cathedral Green for Evensong at Exeter Cathedral (5:30pm Monday to Saturday, 4:00pm Sundays — free, no booking required).

That is a full day of Exeter's hidden history, and almost all of it is free or very affordable. Better still, bring someone with you. History is always more interesting when you have someone to share it with.
