There would have been stone buildings at important
granges, namely, those that were regularly visited by members of
the monastic community. The grange buildings would otherwise have
been timber-framed, as at Cowton, which lay in the North Yorks Moors.
Details regarding the structure and design of the grange buildings
are known from excavations and also from standing remains, for example
the aisled barn at Sutton, which was one of Fountains'
granges, and Wether Cote, the sheephouse associated with Rievaulx's
grange at Sproxton. Excavations at Cowton grange in 1962 uncovered
a stone fireplace and hearth, ceramic roof tiles and grisaille glass
that was used for the windows. It was also shown that when the grange
was brought under lay management, c. 1400, a simpler domestic range
was built.(23) A tiled floor was uncovered
at Brimham grange, which was a favoured retreat for the abbots of
Fountains in the later Middle Ages, who liked to hunt here.(24)
Glazed roof tiles from Fountains' grange at Kirkby Wiske are periodically
found when the fields are ploughed.(25)
Stone roof slates were used on the Nidderdale granges and on some
of those in Craven.(26)
