Origin and history

The Poulailler Oppidum is a major archaeological site located in the Fougères State Forest, on the territory of the municipality of Landéan, Ille-et-Vilaine. This monument, dated from the Iron Age, illustrates the human occupation during Protohistory, a period marked by the development of Celtic societies in Armorica. Its strategic location, above Nançon, suggests a defensive and economic role in the region.

The oppidum was officially recognized for its heritage importance by a 1970 classification of historic monuments. This classification applies specifically to forest plots 36, 37 and 38, identified in the cadastre under references D 155, 169, 171, 176, 177, 179. The protection of this site reflects its archaeological value and the desire to preserve this Breton protohistoric heritage.

The location of the oppidum in a dense forest environment reflects the locational choices of iron age communities, often established on heights for defensive reasons. Although the sources do not mention precise architectural elements, its presence in the Merimée base and its classification confirm its status as an archaeological site of national interest.

The available data do not provide detailed information on searches or artifacts discovered on site. However, its status as a historical monument and its mention in sources such as Wikipedia and Monumentum make it a reference point for the study of Protohistory in Brittany. The accuracy of its location is estimated as "passible" (level 5/10), which may indicate minor geographical uncertainties.

The Poulailler Oppidum is part of a wider network of Breton protohistoric sites, characterized by their role in trade and social dynamics of the time. These oppida often served as places of assembly, protection and territorial control for Celtic populations, in the context of major cultural and technological transitions.

No information is available on current access to the site to the public or on any associated tourism infrastructure. Sources focus primarily on its heritage aspect and legal protection, without detailing its contemporary use or presentation to visitors.
