Description

The winding engine house to Smith's Shaft of West Frances Mine is a derelict structure from the late 19th century, located in Carn Brea, Treskillard. It is built from uncoursed killas rubble with granite quoins and features a bob wall made of large dressed granite blocks. The window arches are constructed from brick, and the chimney has a brick upper stage. The building has a rectangular plan oriented on a north-east/south-west axis, with the bob wall positioned to the north-east and the chimney attached at the south-west corner.

This small building consists of two stages and includes round-headed openings, such as a driver's window in the bob wall and a damaged window in the west side wall. The tapered cylindrical chimney is intact and lacks a cornice between the stone and brick stages. Historically, it is believed that the engine house also operated stamps. Although the site is now isolated, it serves as a visual link among the remaining engine houses along the Great Flat Lode, marking its significance in the mining history of the area.
