There was a church at Amesbury from the foundation of the abbey in 979 and it is possible that there may have been a church before that. It is thought that the dedication of the church was to St. Mary and that it became a joint dedication when the relics of St. Melor were brought to the abbey. The abbey church itself would have been open to all inhabitants as there would not have been any other church. The abbey was dissolved in 1177 and the church was granted to Amesbury Priory which, by 1186, had built a new church. It was believed that the original abbey church then became the parish church although there has been disagreement over this. If you walk around the church today you certainly receive the impression that it has been more than a parish church in the past but there is now general acceptance that Amesbury had both a priory church and a parish church and that it is the latter which has survived.
