3/8 Engine House at SW595307 Leeds Shaft Great Work Mine and associated remains

GV II

Beam. engine house ruin and associated remains. Circa 1829. Granite rubble walls with dressed granite quoins and jambstones, granite ashlar bob wall, two granite keyed round brick arches otherwise wooden lintels. Rectangular single cell plan with thicker bob wall at the south side. Floors, roof and machinery removed. Three storeys over basement pit. South bob wall has central round-arched ground floor opening (plug doorway). Ashlar masonry reinforced with later iron bands. Weather boarding to 2nd floor and gable removed. Opposite north wall has similar ground floor arched opening (known as the boiler doorway), with smaller opening to 1st floor over; small holes for 2nd floor beams and window opening to 2nd floor with masonry of gable missing above lintel level. Two irregularly disposed openings to each side (wing) wall. Foundations of other structures nearby. This is an unusually old example of an engine house and originally housed a 60" pumping engine. The engine was rebuilt in situ by Harvey in 1857 and worked until the late 1890s. It was a 'high duty' engine, i.e. an engine that exceeded the average efficiency attained by pumping engines in Cornwall as recorded in Lean's monthly statistics.
