Origin and history

The Palais d'Argentré, located in Sées in the Orne department, is a former bishopric built in 1778 by architect Joseph Brousseau for Jean-Baptiste du Plessis d'Argentré, then bishop of Sées. This emblematic building of the 2nd half of the 18th century reflects the aristocratic architecture of the period, with its corner pavilions, its honorary courtyard closed by a gate, and its neat interiors (living rooms, carpentry, marble fireplaces). It embodies episcopal prestige in a city marked by its religious heritage, close to the cathedral.

Ranked Historic Monument by decree of 18 May 1908, the palace has had several uses over the centuries. From 1921 to 1940, he housed a seminary, before becoming, from 2018, the Institut d'Argentré-Sainte Anne, a boarding school for young girls affiliated with the Priestly Fraternity Saint-Pierre. Its architecture, combining classical elegance and functionality, makes it a rare testimony of the episcopal residences of the Ancien Régime in Normandy.

The interior layout of the palace follows the cannons of the comfortable 18th century houses: large living rooms, wide clearances, monumental staircases, and period parquet floors. The central body, crowned with a triangular pediment, is framed by two symmetrical wings with rectangular bays. The corner pavilions, with their three bays in front, highlight the architectural balance of the whole. Today owned by the Orne department, the site remains partially accessible, although its current use limits visits to the public.

The palace is part of a historical context where Sées, the episcopal seat since the fifth century, played a major religious and administrative role in Lower Normandy. The construction of the bishopric in 1778 coincided with a period of architectural renewal for the Church, marked by a concern to assert episcopal power through prestigious buildings. The French Revolution, a few years later, will upset this role, but the building will survive as a symbol of local heritage.

The sources available, notably the references of the Mérimée base and the works of René Goblot (Archaeological Congress of France, 1953), underline the importance of the Argentré Palace in the history of Orne. Its early classification in 1908 reflects its heritage value, while its current occupation by a traditionalist institution adds a contemporary dimension to its historical heritage.
