The small town of Mortagne-au-Perche has preserved some beautiful heritage from its past as the historic capital of the county of Le Perche. Its places of interest include: Place du Général de Gaulle, the lively centre of town with a corn exchange; the narrow paved streets lined with old houses; the Flamboyant Gothic-style Notre-Dame church which contains 18th-century wood panelling; the charming garden of the town hall with its formal flowerbeds; Saint-Denis gate, a vestige of the old fortifications; and the Maison des Comtes du Perche, which houses the town library and Musée Alain. This museum is dedicated to philosopher Emile-Auguste Chartier, known as Alain, who was born in Mortagne, and has manuscripts, photos, objects and publications on display. Talks about the philosopher (Les Journées Alain) are held there every first weekend of October.
Each third weekend in March, the village speciality – black pudding (blood sausage) – is honoured during a well-known festival, the Foire au Boudin de Mortagne.
