South Wheal Frances Mine

[3] By the early 20th century, several thousand men, women, bal maidens, and children worked in the mine.

The surviving features include the derelict, roofless winding engine house to Marriott's shaft that was built in the 1890s.

It contained a horizontal cross-compound engine made by Holman's of Camborne, with 23- and 43-inch cylinders either side of its conical winding drum.

[5] The derelict boiler house at Marriott's shaft is built of granite rubble with quoins at the corners and brick arch openings.

Now roofless, it once contained six Lancashire boilers to power a pumping engine, winder, compressor, crusher, and capstan.
