Ancient Roman fortress Sagium, located on the road of tin, the bishopric of Sées was established in the fifth century by Saint Latuin. Located in the heart of the department of Orne, 25 km north of Alençon, the ancient Sagium or Sagio whose first name is mentioned in 991, derives its name from the Gallic tribe, the sagii. In the 7th century, Saint Evroult founded the abbey of Saint Martin. Important religious center, Sées disappears practically with the barbarian invasions. The cathedral destroyed four times is rebuilt in the early thirteenth century in its current form. Until 1465, the city is composed of three villages: Bourg l'Evêque, Bourg le Comte and Bourg l'Abbé. The origins of Sées are therefore tripartite: Roman, feudal and monastic.
During the wars of religion, the city is plundered by Montgommery.
At the time of the Revolution, Sées had five parishes. The Comte de Provence, the future Louis XVIII, had his tutor appointed, Monseigneur du Plessis d'Argentré, bishop of Sées. It fills the region with its benefits and builds a majestic episcopal palace.
Today, Sées is one of the four chief towns of the canton of France, which is the seat of a bishopric. The episcopal city has kept over the centuries the charm of small towns by integrating in its landscape, amenities useful for everyday life. Sées is named in 2018 "Small City of character of the Orne".
