Built of local sandstone; St Peter and St Paul's is only a part of the original priory; but a very fine one. There is a large tower at the W. end with a marvellous 12th-century carved doorway. The N. side is the old monastic church with fine Norman arches; in the centre is the 13th-century parish church; and to the S. is a 14th-century aisle with magnificent Decorated windows ornamented with a profusion of ballflowers both inside and out: an instructional mix of every building style.
