The medieval fabric of the abbey church is incorporated in the Elizabethan renovation, which converted the E end and central crossing to a handsome, single-storey dining hall. Entrance was via a door at the NW end, now relocated.

The red and white Dutch stone tiles on the floor are 16th c. The hall is panelled in oak on its N, S and W walls, the panels divided vertically by pilasters with Corinthian capitals, surmounted by grotesque figures in high relief. The arcaded top panels each have a carved lion's head at the apex.

The fine 16th c. plaster ceiling was inserted during Sir Richard Grenville's renovations in the 1570s.

The windows on the S wall are early 20th c.
