The history of the second church of the priory of the Mont-aux-Malades is inextricably linked to that of Saint Thomas of Canterbury. When he was chancellor to Henri II Plantagenêt, Thomas Becket came to Rouen and became friends with the prior of the Mont-aux-Malades. Relations between the king and the individual who had become archbishop of Canterbury then deteriorated significantly. The epilogue was the assassination of Thomas Becket in his cathedral in 1170. Having been served an interdiction, Henri II reconciled himself with the Church at Avranches, two years later. Following the canonisation of Thomas Becket, he embarked upon an expiatory pilgrimage to Canterbury in 1174. This was the same year in which he had built a new priory on the Mont-aux-Malades, and a new church, one of the first to be dedicated to saint Thomas of Canterbury.
