Engine house of Cornish type for a steam-powered pumping engine for the Penrhyndu lead mine. The tower may have been built in the late C18 for a Newcomen type engine and altered in the early to mid C19 to take a Boulton & Watt type beam engine. There is no visible chimney, but this would probably have been detached and it is suggested that Tower Cottage may have been a separate boiler house. Lead mining at Penrhyndu may go back to Roman times, there were workings owned by Cymer Abbey in the Middle Ages. Mining is mentioned in 1668 and 1734, Messrs Roe of Macclesfield were working the mine from the 1760s to the early C19. In 1785 John Cartwright and three others erected an engine to drain the mine, but Edward Hyde Hall in 1809-11 found all mining ceased. In 1828 Messrs Williams of Gwennap, Cornwall took over, running the mine to 1839. There was a successful find in 1869, and the mine operated until 1892. In the C19 owned by the Assheton-Smith family of Vaynol.
