The bishop's seat was established at the foundation of the new diocese in 1966 in the parish church of Saint Spire in Corbeil, an ancient collegiate church, which thus became the cathedral. The facilities were however inadequate for the needs of an episcopal administration, and the new town of Évry was chosen as a better-situated new episcopal centre, although entirely lacking in any suitable church building. The purpose-built cathedral at Évry was therefore commissioned, and opened in 1995, superseding Saint Spire as the cathedral of the diocese.
