Around 60 miles, or 90 kilometers, southeast of Paris, the medieval town of Provins is situated on the plains of Seine-et-Marne. Provins is a UNESCO World Heritage site with fortified walls and gates, round towers, and even medieval festivals and fairs. But even more, or just as interesting, is what lies below Provins!
Provins sits above a web of underground tunnels known as the souterrains de Provins. These subterranean passages expand beneath the town in every direction. It is estimated that the total network is roughly 9-12 miles, or 15-20 kilometers, though only around 1 mile, or 2 kilometers, are open to the public. Even some household cellars directly connect to these tunnels! Most of the system is sealed, however, some have collapsed, flooded or are awaiting excavation.
How the Tunnels Were Used
Between the 12th and 14th centuries, Provins was one of the six great cities of the Champagne Fairs, which was a cycle of trade fairs that made this part of France a commercial center in medieval Europe. The trade merchants from Belgium, Italy, Germany, and the Iberian Peninsula converged here to trade in cloth, spices, leather, and luxury goods.
And, that volume of commerce needed infrastructure, not just above ground, but below it. The tunnels were used for several overlapping purposes:
- Storage cellars: Merchants would have needed cool, stable-temperature spaces to keep goods, particularly wine and perishables, during the long fair weeks.
- Chalk quarrying: The soft craie removed during tunnel digging was used in construction materials throughout the town.
- Tanneries and workshops: Some chambers served as underground workrooms for trades requiring more controlled environments.
- Refuge passages: During periods of conflict, the tunnels provided escape routes between key buildings and out beyond the town walls.
The construction of these tunnels peaked during the 11th through 13th centuries, but when the Champagne Fairs collapsed in the early 14th century, partly due to changing trade routes and partly due to the Hundred Years' War, the tunnels lost their use. Of course, it's possible they were also used during the Hundred Years' War. And what's this I hear about the Freemasons using the tunnels?
Rediscovery and What Survives Today
The tunnels were supposedly forgotten for several centuries and maybe the locals knew vague stories of passages beneath the streets, but exploration only began in the late 20th century. Today, the accessible sections include several interconnected passageways reaching depths of up to 26 feet, or eight meters, below street level. The galleries average about 5 feet, or 1.5 meters, in height and require many modern visitors to stoop down.
Inside, the temperature holds at 55°F, or 13°C, year-round.
There are guided tours (available in French, with audio guides in English) that depart from near the Grange aux Dîmes, the former tithe barn in the lower town that now serves as a visitor center. The tours run approximately 45 minutes and cover the most structurally sound sections of the network. And while photography is permitted, flash tends to flatten the texture of the chalk walls, so it might make sense to bring a camera/phone that performs well in low light, or learn how to change those settings on your camera/phone.
Provins Beyond the Tunnels
The tunnels are one part of the town because above ground, the upper town (ville haute) is surruonded by 12th-century ramparts that are among some of the best preserved in France. The Tour César, is a fortified tower rising 145 feet, or 44 meters, above the upper plateau and offers panoramic views over the Seine-et-Marne plain. The Collégiale Saint-Quiriace is an unfinished Gothic collegiate church that began construction in the 12th century.
The lower town is more lived-in, but has timber facades and the ruins of medieval hospitals and trade halls. The Maison Romane is considered one of the oldest surviving civil buildings in France, with its stonework dating to around 1180.
Provins also runs seasonal historical festivals and fairs like jousting tournaments, falconry shows, and medieval markets creating a unique immersive experience.
Getting There from Paris
Provins is a very accessible (as in, trains reach it) day trip from Paris. The Transilien Line P runs direct trains from the SNCF Paris-Est train station, "Gare de l'Est," and choose the stop “Ville Haute, Provins” which takes about 1 hour and 20 minutes. The station is a 15-minute walk uphill from the lower town entrance. You need to follow the signs for "Ville Haute." There is no need to rent a car unless you are combining the visit with the Forest of Fontainebleau or other Seine-et-Marne sites on the same day.
By car, take the A4 east from Paris toward the Marne Valley, then follow signs for Provins via the N4 — roughly 1 hour 15 minutes in normal traffic. You will need to pay if you visit on the weekend, during public holidays, and from the last weekend of March to All Saints’ Day weekend (beginning of November). It is free for the rest of the year. This will cost 4€ for a full day and 2€ for a half day (starting from 1 pm). There is plenty of parking, including parking for people with disabilities.
Just In Case
- Getting in: The tunnel tours are ticketed separately from other Provins sites but there are combined tickets covering the tunnels, Tour César, and the Grange aux Dîmes which offer the best value.
- What to wear: The tunnels are cool and occasionally damp. A light jacket is advisable even in summer, and closed-toe shoes are strongly recommended since the chalk floors can be slick in places.
- Accessibility: Unfortunately, much of the tunnel network is not wheelchair accessible due to low ceilings and uneven footing. The above-ground sites are more navigable, though the upper town involves significant elevation change (hills).
- Best time to visit: The spring and early autumn offer the most comfortable above-ground conditions and the best chance of catching a festival without summer crowds. The tunnels are equally impressive all year-round.
- Duration: It makes sense to expect this to take a full day for a visit that would include the tunnels, upper town, ramparts, and at least one of the museums but half a day covers the highlights if your time is short.
Provins is not a theme park version of the Middle Ages, it is an actual medieval town that has survived. There is a lot of wonder and mystery around this town that makes it an exciting excursion from Paris.
