Description

An engine house at Higher Lansalson (HER No. 27207), first recorded on the 2nd Edition OS 1:2500 of 1907, and visited by CAU in 1990 as part of the china-clay survey. The site is now heavily overgrown with scrub and rhododendron, making access difficult. A chimney stack of granite with iron bands is located at the south end of a boiler house. To the west machinery bases and holding-down bolts may indicate the site of a horizontal steam engine. One of two surviving engine houses associated with Lansalson China Clay Works. In addition to the two engine houses, a shaft and the retaining wall of the downslope side of the boiler pond or reservoir for the engine houses also survives. There is a fuller description of this site in the 2006 The Green Corridor, Wheal Martyn to St Austell, Archaeological Assessment and Watching Brief (HES Report No. 2006R032). Recommended by local Cornwall councillor, Dick Cole, for inclusion in the CLHL and as a potential candidate for statutory protection.
