structure surrounding it. From its position it could contain 
only the water from the cloister roof and a portion of that from 
the nave of the church, an examination of these roofs showing 
that ample provision has been made for collecting the water 
falling upon them and distributing it on the ground so that it 
could find its way into the well. 
It seems, therefore, that this well received only the water 
from the roofs of the monastic buildings and falling on the 
ground within the rectangle formed by the cloisters. 
I would suggest that the water from this was only used to 
fill the stoups, and the font for baptisms. Neither the amount 
collected, nor the quality, would have rendered it of much 
value for the domestic purposes of the monastery.
