A selective investigation within the scheduled area to the east of the standing remains of the nave has located the south transept and square east end of the priory church. The transept was found to incorporate an undercroft or asymmetrical crypt which extended into the area beneath the crossing, but terminated at some point short of the north transept. Excavation of deep post-medieval disturbance at the east end of the church yielded glimpses of an underlying late Roman building of unknown purpose. The archaeological investigation was the first stage in an improvement scheme for the monument to include landscaping and the marking out of major features in the eastern ground plan of the priory church.<1>
