Origin and history

The château de Chavagne, located in Sucé-sur-Erdre (Loire-Atlantique), finds its origins at the end of the 14th century, when Pierre de Saffré, the great widower of the Duke Jean V of Brittany, erected a first building on the ruins of an old hunting house. This seigneurial house, characteristic of the Lower Middle Ages, was enlarged and transformed in the sixteenth, seventeenth and nineteenth centuries, including an octagonal tower and adjacent houses. An ancient door, decorated with a coat of arms probably linked to the family of Saffré, bears witness to this founding period.

The property remained in Saffré's family until 1489, before being acquired in 1571 by Jean Morin de La Sorinière, a Haitian magistrate and first president of the Chamber of Accounts of Brittany. His son-in-law, Joachim Descartes (father of the philosopher René Descartes), inherited him in 1609, making the castle a residence of the "Descartes de Chavagne". René Descartes occasionally stayed there, as attested by his signatures in the local civil registry (1617, 1622, 1628, 1644).

The castle changed hands in 1688, sold to Claude Luzeau de la Grande-Noë, then passed on to his descendants, including Louis Maurice Luzeau de la Mulonnière in the 18th century. Ranked Historic Monument in 1994 for its facades, roofs and houses, it illustrates the architectural evolution of a seigneurial residence, linked to the political and intellectual history of Brittany and the Pays de la Loire. Its registration protects a heritage marked by influential families, from parliamentarians to local notables.
