This attractive engine house was built to house a 70" pumping engine which was never fitted. The engine house chimney is unusually castellated and is believed to have been built identical to that of Wheal Golden. Wheal Ellen can be found at NGR SW703468 close to the Tywarnhayle workings. The company that built the engine house in 1866 had intended re-working the original sett in conjunction with nearby Wheal Music under the name Ellen United Copper and Zinc Company, however nothing else is heard of the new concern post 1866. The mine was known to have produced some 24,000Tons of copper from 1826-62 during previous operations.
