Château du Plessis, Casson

Château du Plessis is a manor house in Casson with protected facades and distinctive rooflines developed over two centuries of expansion. Inside, it contains a grand staircase with wrought iron railings and a formally decorated salon furnished in the Empire style of the early 1800s.

Built in 1753 by architect Jean-Baptiste Ceineray for a member of Brittany's Parliament, the house reached its current form by 1805. This reflects the period when wealthy families expanded and modernized their country estates.

The estate carries the name of a noble family connected to this land for centuries. Visitors can still see the park-like surroundings with romantic features such as the pond and grotto that were created in the 19th century.

The house sits at the entrance of Casson village, north of Nantes, and remains a private residence. Visits require advance permission from the owners, especially if you hope to see special events or guided tours.

Records of lordship on the land stretch back to 1260, unusually far for a single French estate. Among notable residents was François Dollier de Casson, who later shaped the urban planning of Montreal.
