6/191 Engine house and capstan plat at SW 598265, Old Shaft, Trewavas Mine

GV II

Beam engine house ruin, for pumping engine and adjoining capstan plat. Circa 1834. Dressed coarsed granite bob wall, otherwise granite rubble with dressed granite quoins and jambstones and wooden lintels. Rectangular, plan engine house with thicker bob wall with small plug doorway at the seaward side. Very tall opening in the rear landward side, necessary for the insertion of the beam and boiler from the steep slope of the cliff. Machinery, floors, framed wall and gable over the bob wall and roof structure removed. Rear gable fallen. Wing walls each have ground floor doorway and first floor windows the right hand wall also with ground floor window. Originally with 3 floors. The building is set on a ledge half way up a steep cliff, the shaft immediately in front and the front left hand corner built over a sheer drop of nearly 100 feet to the sea. The capstan plat adjoins at the left hand side of the engine house and is retained by a battered granite rubble wall, serpentine on plan. Within the plat is a masonry lined pit for holding the capstan drum and leading from it, a masonry lined trench through which the rope ran out to the pulley at the base of the sheer legs over the shaft. The manually operated capstan was used for lowering heavy pieces of pumpwork down the shaft. Higher up the cliff, to the north west, is a horse whim plat used for hauling ore trucks up a tramway. Wheal Trewavas was a copper mine worked between circa 1834 and 1846. In 1844, the sea apparently broke into some of the workings just before a tributer's dinner was due to be held underground. These remains have one of the most spectacular settings in Cornwall and the capstan plat pit and trench are easily the best preserved in Cornwall (Kenneth Brown).
