Origin and history
L'oppidum d'Incheville, also known as Camp de Mortagne, is a major archaeological site located in the commune of Incheville, in the Seine-Maritime department of Normandy. This monument, dated the Iron Age, covers an area of 28 hectares, although some sources, such as Mortimer Wheeler, have proposed an estimate of 12 hectares. It is protected by an impressive rampart, measuring between 7 and 8 meters high and extending over a length ranging from 82 to 344 meters. Two doors pierce the southern rampart, highlighting the strategic importance of this site.
The site is located southeast of the village of Incheville, instead of Camp de Mortagne, in the Bresle valley. Only 2.5 km away is another notable archaeological site, Briga. The Incheville Oppidum may have marked the boundary between the territories of the Calètes and the Ambiens, two Gaulish peoples, or belonged to a small people named the Catuslugi. Although the site was not the subject of extensive excavations, significant discoveries were made there, such as a skyphos dated the 6th or 5th century BC, found in Bresle in 1872 and today preserved at the Museum of Antiquities of Rouen.
Abbé Cochet reported the presence of graves near the site, dated the 4th and 5th centuries, whose funeral furniture was integrated into the collections of the museum of the antique shop of Picardie in Amiens. Artifacts discovered on or around the site include flint grinding wheels and a Roman tile oven, attesting to a prolonged and diversified occupation. The oppidum was listed as historic monuments on 3 February 1984, thereby recognizing its heritage and archaeological importance.
The protected elements of the oppidum include several cadastral plots, covering areas such as Bourg, Ferme de Mortagne and Breuilly. The site is now partly owned by the State and partly private. Despite the absence of exhaustive excavations, the archaeological evidence collected makes it possible to consider oppidum as a central place in the territorial and social organization of the Gallic peoples of the region during the Iron Age.
