which has a curved end and 2 segmental-headed windows; the

and casements with margin panes, and paired right-hand 2-light

INTERIOR: a winder stair up to the camera obscura in the roof,
and down into a tunnel leading to Ghyston's Cave, in the side
of the gorge.
HISTORICAL NOTE: the windmill was damaged by fire in 1777.
William West leased the mill for conversion into an
observatory in 1828. In 1835 he was granted an extra piece of
land adjacent to the tower on which he built a new
astronomical observatory with a revolving dome and telescope
"to allow unrestricted observation of the heaven". Next to
this was a large room with various astronomical maps, globes
and instruments, intended for occasional use as a lecture
room. The tower was also altered in 1835, by the rebuilding of
the wooden balcony in store and the fitting of the camera
obscura. West also excavated an underground passage to
Ghyston's Cave, opened 1837.
