In Ivry-la-Bataille can be seen the remains of one of the first stone castles built in Normandy circa 1000 AD. When you visit the ruins you can imagine the size of the fortress and the magnitude of the keep that testify to the strategic importance Ivry had for centuries. Ivry's name evolved into Ivry-la-Bataille after the battle of 1590 won by Henry IV of France against the Duke of Mayenne. A pleasant walk provides a view over the town and the Eure river dotted with watermills and waterworks that remind us of the important industrial past. Along the streets with evocative names, "rue des belles femmes" (pretty women's street), "rue de la porte à bateaux" (boats' door street), or the "rue de la prison" (Jail street), admire Norman half-timbered houses and take a look at the door of the former abbey. Do not miss: Calvados Morin and the visit of the troglodytic cellars.
