The excavations linked to the laying out of a racecourse at a locality named “ Le Fond de Randillon “ at Mauquenchy in the north east of the department of la Seine Maritime, in a natural area, with a well marked character, the Pays de Bray, led to the discovery of two ancient agricultural settlements. Founded during the periods of Augustus and Tiberius ( c. 27 BC – 378 AD ), they seemed about to collapse round the middle of the 2nd century and to have disappeared round the beginning of the 3rd century AD. These sites settled at the edge of the regions of the Calètes and Bellovaques and characterized by buildings on stilts and by a system of rectilinear ditched enclosures show very comparable physical features which evoke models of ancient farms directly inherited from the Gallic period.
