Porte Saint-Denis, Mortagne-au-Perche, Medieval gate in Mortagne-au-Perche, France
The Porte Saint-Denis is a gate in Mortagne-au-Perche featuring a large archway for carriages with two upper floors marked by Renaissance-style galleries on the north-facing side. The structure stands on Rue de la Porte-Saint-Denis and received registration as a historical monument in 1975.
Built between the 12th and 13th centuries, it served as one of the principal entrances to Fort Toussaint and remains the only surviving structure from that fortification. The gate is an architectural trace of what was once a major defensive stronghold.
Inside, two rooms on the first floor display wooden panels decorated in Louis XVI style from the 18th century. These interiors reflect the craftsmanship and elegance that defined the period when the building served important functions.
The gate is easily reached on foot from Rue de la Porte-Saint-Denis in the town center. The surrounding area offers clear sightlines and space to view both the front and side facades from different angles.
The south-facing side originally had two corner towers that no longer exist today. Over time, the galleries on the north side were filled in with walls, significantly altering the gate's original appearance.
