It may seem odd that the Prior should have his own chapel, but as a Priest he was committed to saying Mass everyday, as Priests are even today, and this was where it would usually happen. The chapel is on the top floor of the two-storey building, and probably dates from a remodelling in the later 14th century. The top storey is divided into the chapel and the Prior's private chamber, although the existence of a piscina and an angel corbel in the chamber suggests that there had been an earlier chapel here.
