Château de Châteaubriant

Highlight • Castle

Châteaubriant Castle is a medieval castle transformed into a Renaissance palace. There you can discover the impressive fortifications, the elegant dwellings and the mysterious legend of Françoise de Foix, who died in the castle under mysterious circumstances. You can also admire the exhibition “In the Ink of Dreams”, which presents the works of contemporary artists inspired by the castle and its history. The castle is open every day from 9:00 a.m. to 6:00 p.m.

La Forge Neuve

Highlight • Historical Site

A vast industrial forge site dating back to the 17th century. The natural setting is also remarkable, with the dam on the Don River creating a splendid reservoir that supplied the forges. A favorite is Rue des Rochers Bleus and its hanging pine tree.
