Stonework
Description of the stone
The bulk of the original wall fabric is built from fine grained, pinkish brown
to greenish grey sandstone ashlar blocks. Characteristic features of the stone
include low angled cross-bedding of the sandstone. In the face of some weathered
sandstone blocks small open holes or pits have developed where weak mineral
cement (probably calcium carbonate) has been removed. The plinth stone is similar
in composition but appears to be a particularly hard sandstone bed. A feature
of this stone is the occurrence of small tubular structures (possibly worm
burrows) which have become preferentially cemented and stand out as small lumps
on the block faces.
The sandstone was probably quarried locally (at Gedling) from the Triassic
Keuper sandstone unit known in the past as the Waterstones. Modern geological
maps and reports now call the unit the Sneinton Formation of the Mercia Mudstone
Group.
Other local buildings using the same stone
Compare church fabrics at Gedling, Woodborough,
Epperstone and Burton Joyce which
all use a similar sandstone.
