Engine House At Sw 434346, Greenburrow Mine

The Engine House at Greenburrow Mine is a grade II listed beam engine house, dating from the mid to late 19th century. It features a granite ashlar bob wall, with the rest constructed from granite rubble and granite dressings. The chimney has a brick upper stage and is positioned at the rear left corner of the rectangular plan. A dressed granite cylinder plinth remains in place, although the former pumping machinery, floors, and roof have been removed.

The structure stands three storeys high over a low basement. The front wall has a round-headed granite arched doorway in the middle, while the rear wall contains a round-headed doorway with a partly fallen brick arch and window openings on each floor above. The side walls have irregularly disposed openings and show evidence of a former extension on the left side. A moulded brick cornice adorns the tapered chimney.

This engine house is a significant monument to the tin-mining industry, having ceased operations in July 1877. It is one of the most prominent landmarks in West Cornwall, visible from Lanyon Quoit and serving as a navigational point for fishermen.
