Oppidum situé dans la forêt domaniale de Fougères, located in Landéan (Département 35), is a historic monument. The monument is currently closed to visitors.
Perched in the national forest of Fougères, this protohistoric Breton oppidum reveals the remains of a fortified Gallic town, a silent witness to a Celtic people who were masters of the Armorican heights.
In the heart of the state forest of Fougères, in this wooded massif that drapes the hills of Ille-et-Vilaine, lies one of the best-preserved oppida in Brittany. These earthen and stone ramparts, now swallowed up by centuries-old oak and beech trees, bear witness to intense human occupation during the Iron Age, at a time when the Gallic peoples of the Great West had mastered the art of fortifying strategic high points. What makes this site truly unique is the rare combination of the exceptional preservation of its defensive embankments and the forest that surrounds them. Unlike many Gallic oppida, which have been razed to the ground by agriculture or urban development, the Landéan oppida has been preserved by the forest cover, which means that visitors can still clearly see the original topography: the succession of V-shaped ditches, the embankment mounds crowning the high points, and the baffled entrances characteristic of Celtic defensive architecture. The visitor experience is fundamentally sensory and contemplative. You walk along forest paths where the silence is broken only by the cracking of branches, looking for the breaks in the slope that reveal the ancient structures. Archaeologists have identified settlement structures, craft areas and traces of grain storage, sketching the portrait of an organised, self-sufficient and defensively hardened community. The natural setting adds an almost mystical dimension to the journey. The Fougères forest, one of the largest state-owned forests in Brittany at almost 2,200 hectares, is itself a remarkable natural heritage site. Hundred-year-old beech trees, ferruginous springs and Armorican sandstone rocks create a backdrop that reminds us that, long before the Roman conquest, these lands were at the heart of a vibrant and powerful Celtic territory.
The Landéan oppidum belongs to the category of high-rise fortifications with continuous ramparts, typical of Gallic defensive architecture in the Second Iron Age. Its layout follows the natural constraints of the terrain: the Celtic builders took advantage of the steep slopes of the forest to minimise earthworks while maximising defensive effectiveness. The enclosed area, estimated at several hectares, was demarcated by a system of ramparts made of earth mixed with local stone - mainly Armorican sandstone and shale - heightened by a wooden palisade, of which only the negative imprints remain in the subsoil. The defensive system combines external V-shaped ditches, a main embankment and a counter-escarp, in a similar way to many contemporary Armorican oppida. The entrances were reduced to simple chicane or bayonet crossings, forcing the attackers to present themselves from the flank, exposing their unprotected shield side. Inside the enclosure, the topography reveals artificial flats that probably correspond to housing areas organised into islands, with semi-buried huts and granaries raised on poles. The materials used were those of the immediate area: clay soil from the plateau, Armorican sandstone blocks taken from the surface and wood from local forests (oak, ash and alder for the piles). The absence of mortar and the exclusive use of dry, earthen construction techniques are characteristic of the protohistoric architecture of western Gaul, quite distinct from the beam-linked murus gallicus found in the oppida of central and eastern Gaul.
