There is a double Early English piscina in the south wall, and an ambry in the north.
ambry, am′bri, n. a niche in churches in which the sacred utensils were kept: a cupboard for victuals.
Betty Lamb found the ambry niche in the wall of the ruin at the side of the place where the altar had been.
There is an ambry in the south wall near the east end, and the doorway is semicircular and of Norman character.
With that he restored the goblet to the secret shelf, put back the drawer, and shut the ambry door.
