or any other patron, and granting immunity from the seizure of their possessions during any vacancy and from any obligation to pay a pension or corrody to anyone. The advowson was regranted to Michael de la Pole the younger in 1398. The plan of the ruins taken by Alfred Suckling in 1848 provides an outline of walls still surviving, which can be recognized in views made by Samuel and Nathaniel Buck (1738), Thomas Hearne (engraved 1781), Henry Davy and others. The "ritual east" of the monastery was orientated somewhat to the south-east geographically. Suckling's plan is described as "entirely inadequate" by Sir Alfred Clapham, whose studies of Premonstratensian architecture laid the basis of modern interpretation. The ruins The remains of the abbey church confirm that it survived the fire of 1380, and show that it was built on an impressive scale. It was laid out with an aisled nave, a central transept crossing supporting a tower, and a presbytery to the east with choir aisles serving as chapels both north (Our Lady) and south (St Michael). The proportions are indicated by the high north wall of the north transept containing the arch of a window 45 feet high, while the length of the church is estimated at 165 feet. The choir aisles, not occupying the full breadth of the transepts, opened into them by a single arch to the west and into the presbytery by two arches supported by columns or half-columns of octagonal section. Their separately pitched roofs are shown by gabled offsets on the east walls of the transepts. Their altar-spaces and eastern walls were closed from the presbytery, which extended beyond by a single bay where the altar was lit by tall arched windows on either side and by a great east window. Externally the east wall and buttresses were embellished with flint flushwork in emergent Perpendicular style, while the offsets of stone tracery in the window-arches of the north transept and Lady chapel indicate curvilinear designs now lost. The piers of the eastern arch of the crossing survive to some height, but without their facing-stones. However fragments of the capital on the north side are of late Norman style, suggesting to Sir William St John Hope that the abbey had never been moved, and to Sir Alfred Clapham (more probably) that piers from the original church had been reconstructed in the new location.
