Église Notre-Dame de Mortagne-au-Perche, Gothic church in Mortagne-au-Perche, France

Église Notre-Dame de Mortagne-au-Perche is a Gothic church featuring a five-sided choir, a main nave with side aisles, and multiple chapels positioned regularly throughout its length. The interior feels spacious due to how these sections connect and flow together.

Construction began in 1494 after the Hundred Years War, replacing a previous chapel that once stood here. Work continued until 1535, creating the structure visible to visitors today.

The north portal, the Porte des Comtes du Perche, has a truncated flamboyant gable and carved wooden door leaves. Inside, the stained glass spans styles from the Renaissance to the 20th century, and 18th-century wooden panelling lines the walls.

The church stands in the centre of Mortagne-au-Perche, fronted by a paved area where cars park, so the west and tower facades are best seen from across this square. The tower, rebuilt only in part after 1890, now holds the clock and bells. Visitors enter through the doors of the nave and move freely among the side aisles and chapels.

The tower's demolition in 1890 exposed the site of one of the corner towers of the first town wall, known as Toussaint. The bell tower was then only partially rebuilt, just enough to house the clock and bells. The church itself, apart from the tower, has been classified as a historical monument since 22 January 1910.
