Abbaye de l'Isle-Dieu, Medieval abbey in Perruel, France.

The Abbaye de l'Isle-Dieu, the only Premonstratensian foundation in the Eure department, stands in Perruel near Vascœuil. Its abbey church was consecrated in 1207 by Archbishop Gautier de Coutances, and from 1209 to 1220 the community used Caumont stone for its buildings. A new church was consecrated in 1267 by Eudes Rigaud, Archbishop of Rouen.

The abbey was founded in 1187 by Regnault de Pavilly, Raoul de Perruel and Gilbert de Vascœuil, on the advice of Hugues de Saint-Jovinien, who settled hermits on the Île du Houlme. The first canons came from Silly, with Robert de Thaon as first abbot. Gautier de Coutances consecrated the abbatial church in 1207, and Eudes Rigaud consecrated a new church in 1267.

The abbey stands as a testimony to Premonstratensian architecture and represents one of the few remaining examples of this religious order in the Eure department. Visitors can still observe the distinctive characteristics of this building style in the structures that remain today.

The site functions as an active industrial facility, so access to the interior is restricted and the buildings are best viewed from outside. Before planning a visit, it is wise to check current accessibility options, as restrictions may vary depending on ongoing industrial operations.

The abbey's English domain, given by Regnault de Pavilly, let it found Charlton Priory in Wiltshire, confirmed in 1188 by Henry II and Bishop Hubert Walter. Nothing of that priory survives; it was alienated in 1380 and attached to St Catherine's Hospital in London. The abbey also held Saint-Julien de Mantes, founded by Philip Augustus in 1222.
