Priory Walls, including North, West and Postern Gateways

The Priory Walls, which include the North, West, and Postern gateways, are a significant structure dating from the medieval period. These massive walls are constructed of stone rubble and feature an embattled parapet. They extend southwest from the former Almonry, connecting the three gateways.

The North gateway is characterized by a tall segmental-headed arch that has two pointed-headed niches above it, along with a parapet walk at the rear. There is also an arch made of dressed stone on the eastern side, adjacent to the former Almonry. The West gateway boasts a wide segmental-headed arch made of dressed stone, and to the south, there is a narrow pedestrian arch with a chamfered architrave. The Postern gateway features a curved-headed arch of dressed stone topped with a gable.

To the east of the Postern gateway, the wall is lower and includes corbels near the southwest corner. The wall then turns at approximately a right angle to run in a southwest to northeast direction, roughly parallel to the southeast elevation of the Deanery.
