Wanlockhead Beam Engine

The Wanlockhead beam engine is the only remaining original water-powered engine in the United Kingdom. It is a Scheduled Industrial Monument, considered to be of national importance, and is located in Dumfries and Galloway, Scotland. Originally made of pitch-pine and cast-iron step plummer blocks, the engine was built in the late 19th century. Despite ceasing operation around 1910, it remains at its original location by Wanlock Water on the B797. It has been suggested that the engine acted as a supplementary pump for draining water from the disused parts of the Straitsteps lead mine, which operated as far back as 1675.
