In an attempt to get Pope Celestine III to intercede, Walter de Coutances left for Rome in November 1196. Richard sent a delegation to represent him in Rome. One of the party, Richard's Lord Chancellor William Longchamp (who was also Bishop of Ely), died during the journey, although the rest, including the Philip of Poitou, Bishop of Durham, and Guillaume de Ruffière, Bishop of Lisieux, arrived in Rome. Walter de Coutances meanwhile issued an interdict against the duchy of Normandy which prohibited church services from being performed in the region. Roger of Howden detailed "the unburied bodies of the dead lying in the streets and square of the cities of Normandy". Construction began with the interdict hanging over Normandy, but it was later repealed in April 1197 by Celestine, after Richard made gifts of land to Walter de Coutances and the diocese of Rouen, including two manors and the prosperous port of Dieppe. The site of Château Gaillard had not been fortified before, and the town of Petit Andely was constructed at the same time; together with the historical Grand Andely, the two are known as Les Andelys. The castle sits on a high limestone promontory, 90 m above Les Andelys and overlooking a bend in the River Seine. The castle was connected with Les Andelys through a series of contemporary outworks.
