Full description

Engine house.

Marked on (S1) as Engine House, this is a remarkably fine structure consisting of a large barrel vaulted chamber under a mound. It is entered from the east by steps down a cutting; to the south is a high level window or door above a sluice; to the north a long brick tunnel stretches away. In the centre is an upright axle with turbine wheel at the base; to the west is a small engine of some sort in a recess. This is stated by the present owner to have been a hydraulic ram installed in 1850 and used to pump water from the lakes to the hall and garden. However, it looks more like a hydro-electric plant worked by the fall from one lake to the other, and it is known the estate had an early example of such plant installed by Green and Carter.
