Gisors is an exceedingly picturesque old town possessing a fine castle and a very beautiful church. Standing on the little River Epte, it was on the frontier of Normandy, and its importance in medieval times was due to this fact. It was William Rufus who realized the strategic value of the place, and, having obtained possession of it, Robert de Bellesme in 1097 built him a castle, the keep of which, raised upon an artificial mound, is standing to-day. The first two Henrys of England strengthened the castle with towers, and in 1196, when Gisors was ceded to Philippe Auguste at the Treaty of Louviers, still further building was carried out, including a subsidiary keep on the outer line of defence, now called the Tour du Prisonnier. A considerable portion of the eleventh-century walls of Rufus’s castle are still standing.
