The corn-mill is the most complete of its kind in England
and probably the oldest Cistercian mill in Europe.(127) Although
the cornmill has not been excavated, it has undergone rigorous
archaeological analysis.(128) This three-storey
building originally extended over 100 feet long and was over 25
feet wide. In the thirteenth century the building
was extended and
a third storey added to house a granary. Much of this thirteenth-century
structure survives.(129) The cornmill was driven
by a mill-race. To create this, part of the River Skell was diverted,
about two hundred
yards uphill from
the mill. At the time of the Dissolution in the sixteenth century,
the cornmill was driven by two undershot wheels and was considerably
larger than most
other structures of this kind in England; in fact, it has been
suggested that it was more similar to French than English water-mills.(130) The
cornmill continued to function after the Dissolution and remained
in use until
1937.
