Abbaye de Saint-Maur

Abbaye de Saint-Maur is the ruined former abbey at the heart of Saint-Maur-des-Fossés, a town on the Marne just southeast of Paris in the Val-de-Marne department. The old monastery grounds are now a municipal park, and its only fully intact building — a medieval tower — still rises above the lawns and pathways.

What is the history behind the abbey?

The monastery was founded in 639 under the regency of Queen Nanthilde, mother of Clovis II, on a spit of land shaped by a bend in the Marne river, built over the remains of a former Roman castrum. It was first known as Saint-Pierre-du-Fossé, a name referring to the steep bank dropping down to the water. The abbey was enlarged in the 11th and 13th centuries and grew into a respected monastic school.

Its turning point came in 1137, when the cult surrounding the relics of Saint Maur — brought to the abbey in 868 — sparked a well-known pilgrimage tied to a miracle attributed to the saint. The site's reputation grew so strong that in 1281 the abbey was renamed Saint-Maur-des-Fossés, becoming one of the major pilgrimage destinations in the Île-de-France region, drawing visitors until the 16th century.

The monastery fell into neglect during the 17th century and was gradually torn down starting in 1750. Only a handful of elements survive today: the Gothic Rabelais Tower, dated to 1360; a single pillar from the 13th-century abbey church; the apse of the Notre-Dame-des-Miracles chapel, built between the 12th and 14th centuries; part of the old cellar; and a network of underground passages.

What can you see on site?

The Rabelais Tower is the highlight — the only building to survive intact, listed as a historic monument in 1924, together with a stretch of wall connecting it to the abbey's former entrance gate. Nearby stand the remains of the Notre-Dame-des-Miracles chapel apse and the lone pillar that once belonged to the abbey church.

The whole former abbey site is now the Municipal Park of the Abbey (Parc de l'Abbaye), itself listed as a historic monument in 1962. The town of Saint-Maur-des-Fossés, which owns the land, has traced the footprint of the old cloister and the abbey church using hedges and flower beds, so a walk through the park lets you picture the medieval monastery's original layout.

How do you get there and when should you visit?

The Parc de l'Abbaye sits in the center of Saint-Maur-des-Fossés, in an easily reachable riverside part of town roughly 15 km southeast of central Paris. It is a quiet, free-to-visit spot, well suited to a walk combined with exploring the town's riverbanks along the Marne. Spring and summer are the best times to come, when the flower beds most clearly trace the abbey's old floor plan, though the park stays open year-round.

Frequently asked questions

Is there more left of the abbey than just the tower? Yes — besides the Rabelais Tower, visitors can still see a pillar from the former abbey church, the apse of the Notre-Dame-des-Miracles chapel, part of the old cellar, and underground passages, though these now survive only as isolated fragments of the original complex.

Where does the name Saint-Maur-des-Fossés come from? The monastery was originally called Saint-Pierre-du-Fossé. It was renamed in 1281 in honor of Saint Maur, whose relics arrived at the abbey in 868 and around which a major pilgrimage cult developed.

Is entry to the park free? The Parc de l'Abbaye is an open municipal park, so walking the grounds and viewing the ruins requires no ticket.

Can you go inside the tower? The Rabelais Tower is occasionally opened to the public during guided tours organized by the town and local history associations — it is worth checking the current events schedule before visiting, since on a typical day the park is best explored from the outside.
