Shelfmark: Additional MS 15538
This chapel was part of the prior's country retreat, Beaurepaire. The site is now a ploughed field, but its shell was substantially intact when Grimm drew it.
Entered from the south end of the prior's hall, the chapel was built on an undercroft. The original building was remodelled late in the medieval period, so 13th-century lancet windows alternate with two-light windows dating from the late-15th or early-16th centuries.
At the east end of this interior view of the south wall, the former position of the altar is marked by a double piscina, which was a special sink used by the priest to wash his hands and the sacred vessels used in the celebration of mass.
