The site of the castle at Neuville was the subject of two diagnoses supplemented by documentary research and surface observations outside the areas covered by the two archaeological explorations. The imposing remains of a medieval building were revealed. This structure, with its monumental characteristics, belongs to the castle of Neuville. Reoccupied during the First World War by the German army, this building underwent interior reorganization and featured a painted drawing. Shelled in the course of the conflict, it was subsequently largely backfilled. A restitution of the outline of the castral enclosure is proposed. Collation of the various data obtained leads to a consideration of the siting of the castle built shortly after the 16th century Religious Wars, when it replaced the former medieval fortress. Last, the extent of the graveyard that occupied the space between the church and the castle has been in part delimited. One of the graves excavated indicates a relatively early occupation of this funerary area in the years 1170-1268. Traduction : Margaret & Jean-louis CADOUX
