A Castle Designed to Endure

Contrary to castles erected on lofty heights, the Fougères Castle harmonizes with its surroundings, hidden within a bend of the River Nançon. Defense Arena, a hydrologic attribute, became a tactical advantage by the 11th century: the wetlands turned the valley into a natural fortress, slowing down any frontal attacks. Initially, a simple wooden outpost stood on this site and was eventually rebuilt in stone in 1176 by Raoul II, Baron of Fougères, after it had been seized by Henry II Plantagenet's troops.

The construction materials came from the nearby terrain: schist from the heights of Fougères formed the ramparts, while granite served for the foundations, frames, and towers. The fusion of power lies in the fortress's division into three interlocking enclosures, boasting a military courtyard and a noble residence situated at a higher elevation.

Centuries of Conflict

The castle's evolution mirrors the developments in warfare technology. The early towers were square, vulnerable to side attacks. Round shapes swiftly gained popularity, bringing about the creation of circular formations like Hallaye, Guémadeuc, and Coigny. These rounded towers, better adapted to withstand bombardment, eliminated blind spots and amplified the risk of assaults.

Around 1350, the counts of Alençon considerably altered the castle's design. The Tower Mélusine, the second keep, emerged. A chapel and a reception room adorned the residence, marking a shift towards more residential uses. In 1449, conflicts resurfaced: François de Surienne seized the castle through deception. The Bretons retaliated and constructed the Raoul and Surienne towers, designed for artillery, boasting star-shaped cannon platforms and walls nearly four meters thick.

An Engaging Journey Through Time

Since 2009, the tour of the castle has been based on an interactive and immersive experience, spanning approximately 1.5 hours across three of the thirteen towers. Immersive sound effects, videos, and tactile models at each stage make understanding the defensive functioning of the site more engaging.

Accessibility is paramount to the tour experience, with five-language audio guides, French Sign Language supports, and paths tailored for people with reduced mobility. Adding to the tour, both context and artifacts are continuously updated, with informational panels detailing siege techniques and materials used.

A Vibrant Medieval Festival

Every Thursday evening during the summer, the Thursday Castle Nights reanimate the town of Fougères. Armored combat demonstrations, archery workshops, medieval performances, and torchlit night tours attract both families and curious history buffs. These gatherings contribute to lively attendance: 137,000 visitors crossed the moat in 2024, according to the Fougères city hall. Listed as a Historic Monument in 1862, the fortress has been owned by the city since 1892 and benefits from ongoing maintenance and Mammoth restoration projects, with the latest completed in 2013.
