Engine House at Sw584316, Wheal Junket, West Godolphin Mine

The engine house at Wheal Junket, part of the West Godolphin Mine, is a disused beam engine house dating from the late 1860s. It features granite rubble walls with dressed granite quoins and jambstones, along with a granite ashlar bob wall. Most openings are spanned by round brick arches, while some have timber lintels. The chimney has a brick upper stage. The building has a rectangular single cell plan with a thicker bob wall on the northeast side and a round chimney at the west corner. The floors and machinery have been removed, and the structure stands three storeys over a basement. The northeast bob wall includes a large central round-headed opening on the ground floor. The weatherboarded second floor and gable end have been removed. There is a similar ground floor opening on the southwest gable end wall, with smaller round-headed openings on each floor above. The side walls have irregularly disposed mostly round-headed openings. The northwest wall shows signs of a former adjoining building, likely the boiler house. The tapered rubble chimney rises to a moulded brick collar, topped by a tapered banded brick shaft with a brick cornice. The engine house was operational until around 1890 and was previously known as North Great Work. It is in unusually good structural condition and is prominently situated.
