The undercroft of the monks’ dormitory
was probably used as a day-room. This was a large vaulted room
which offered space for the brethren to work and perhaps also to
copy manuscripts. In the later Middle Ages the area was divided.
There was a yard to the east of the day-room, and the building
was supplied with water. A trough found here may well have been
that used for the weekly Maundy, the ritual washing of the monks’ feet
in memory of Christ, who washed the disciples’ feet. Part
of the lead piping can still be seen.(33)
