There was a church in Bruton in 688 dedicated to S. Peter. This gave place to a Norman Church dedicated to S. Aldhelm and S. Mary. In 1142 Earl William de Mohun founded a house of Augustinian Canons who were the impropriate rectors of the Parish Church. The Church then became an Ecclesia Conventualis with two sets of worshippers and one ministering body: the chancel, dedicated to S. Mary the Virgin, patroness of the Priory, was used by the Canons, while the parish altar of S. Aldhelm was moved into the nave, which then became the Parish Church of Bruton.
