SW 62 NW BREAGE

7/193 Engine House at SW 600265, New
Engine Shaft, Trewavas Mine

GV II

Beam engine house ruin for 45" pumping engine. Circa 1838. Granite rubble with
partly dressed granite quoins, jambstones and lintels and dressed granite voussoirs
to round arch of plug doorway.
Rectangular plan with thicker bob wall south west with tall plug doorway from pit
floor level. Machinery, floors, studwork wall and gable over bob wall and roof
structure removed. Originally 3 floors over basement pit towards front. Set on a
steep cliff, the shaft in front of the bob wall on the seaward side.
Bob wall has tall central round-headed plug doorway to basement and ground floor.
Rear wall has ground floor boiler doorway and first and second floor window openings,
the gable over the upper opening fallen. Each side 'wing' wall has 2 ground floor
openings widely spaced and central first floor opening, the first floor window in the
right hand wall blocked.
In front of the bob wall on the left hand (west) side of the shaft is a masonry slot
for the former balance bob (probably added when the mine was too deep for the main
beam to carry the load by itself). North west of this is a capstan plat and a little
higher up the cliff a horse whim plat.
Wheal Trewavas was a copper mine worked between circa 1834 and 1846.
This engine house, and its associated features, is spectacularly situated about three
quarters of the way up a steep cliff and is part of a particularly complete group of
mining remains.
