Origin and history

The former feudal enclosure of Port-Jérôme-sur-Seine, located in the Seine-Maritime department in Normandy, dates back to the 11th and 13th centuries. This monument, now partially buried, bears witness to the medieval defensive organization typical of this period. Its remains, spread over cadastral parcels A 187 and 197, were protected by a registration order under the Historical Monuments on 13 September 1989, highlighting their archaeological and heritage value.

The location of the enclosure, near the Seine, suggests a strategic role in the control of river and land routes during the Middle Ages. At that time, feudal enclosures served both as protection for local populations and as a symbol of seigneurial power. Their construction reflected the political and military tensions of Normandy, a region often disputed between the Duchy and the Kingdom of France.

Available data from sources such as Monumentum and the Merimée database indicate that the site is now owned by the commune of Notre-Dame-de-Gravenchon, although its approximate address is associated with Port-Jérôme-sur-Seine. The accuracy of its location is assessed as "very satisfactory" (note 8/10), thus facilitating its geographical identification. No information is provided on its accessibility to the public or on any tourist facilities.

The lack of details on sponsors or specific events related to this forum limits the understanding of its particular history. However, its designation as Historic Monuments guarantees the preservation of remains, whether they are in elevation or buried, thus providing potential for future archaeological research.

The Norman context of the 11th and 13th centuries was marked by a feudal society structured around local lords, abbeys and developing towns. Premises such as Port-Jérôme-sur-Seine played a key role in defending the territories, but also in economic organization, securing trade along the Seine.

Today, this medieval heritage, though discreet, recalls the historical importance of Normandy in the construction of French territory. His study makes it possible to better understand the dynamics of power and the techniques of fortification in force during the central and late Middle Ages.
