Within one hundred and fifty years after the erection of the priory church, another sacred edifice was required for the growing population around; and Bishop Stapeldon, on Friday, October 29th, 1311, consecrated one in honour of the Virgin Mary, for the use of the parishioners. The present chancel and north aisle of Plympton St. Mary Church are portions of the church then dedicated, the great body of the church, as we now see it, having been re-built in a later age and style. It was situate “_infra cemeterium prioratus_”; and, as a mark of subjection, the parishioners were required to assist at divine service in the conventual church on the feast of its dedication, and to receive the blest palms there on Palm Sunday, and walk in the solemn procession of that day. This obligation was sanctioned by Archbishop Courtenay, when he made a visitation of the diocese of Exeter in 1387, and confirmed by Pope Boniface IX. For some neglect of this ancient custom Bishop Lacy expressed his high displeasure, and enjoined its strict observance in the future. In Plympton St. Mary parish there were several chapels, subject to the priory—one at Newnham, another at Hemerdon, and a chapel attached to a lazar-house, of which there are now no remains. Sutton or South-town, now part of Plymouth, belonged to the priory of Plympton. “In the priors’ court there the portreve of the commonality was elected and sworne into office by his steward, and the markets, the instruments of punishment, and the assize of provisions belonged to him.”
