Origin and history
The castle of Ancenis, built around 984 on the banks of the Loire, has its origin in an initiative of Aremberge, wife of Guérech, Count of Nantes and Duke of Brittany. At the time, it was a castral mot: a wooden dungeon erected on a terre, surrounded by a ditch and a palisade. This rudimentary mechanism was used to protect the local population while controlling river traffic, giving the site a dual military and economic importance. Its strategic position quickly made it a key point for river monitoring.
In the 15th century, the medieval fortress was strengthened with sophisticated defensive arrangements, including a unique access system. A covered drawbridge, arranged in chicane, and a arched vaulted gallery equipped with a harrow provided optimal protection. These elements reflect the evolution of fortification techniques, adapted to the needs of the time and external threats.
Ranked a historic monument on November 2, 1977, the Castle of Ancennis has its protection extended to all its fortifications, as well as to the facades and roofs of its iconic buildings. These include the Renaissance house, the old chapel and the so-called "Mary Fouquet" house. This classification underlines the heritage value of the site, a witness to the architectural and political transformations of Brittany throughout the centuries.
