Crypte Saint André de la Collégiale De Toussaint

Crypte Saint André is an underground chamber beneath the former Collegiate Church of Toussaint in Mortagne-au-Perche. It features stone vaults and sturdy columns that show Gothic architectural style from the thirteenth century.

Built in 1203 by Mahaut of Bavaria, Countess of Perche, this crypt is the only surviving part of the Collegiate Church of Toussaint, which was destroyed during the French Revolution. It survived the turmoil of that era while the church above did not.

The crypt reflects how medieval communities built sacred spaces underground in the Perche region. Walking through it shows the religious traditions that shaped local life during the Middle Ages.

You can visit this crypt on Fort Street free of charge, with parking available nearby. The location is easy to reach and explore on foot once you park.

This crypt is one of the few places where you can see original medieval structure from above while the church it belonged to completely disappeared. It offers a rare window into thirteenth-century building techniques that few other sites in the region preserve.
