Black Country Living Museum which was used for pumping water from coal mines on Lord Dudley's estates. In 1986, after ten years of research, the museum completed the construction of a full-scale working replica of the engine. The "fire engine" is housed in a brick building from which a wooden beam projects through one wall. Rods hang from the outer end of the beam and operate pumps at the bottom of the mine shaft which raise the water to the surface. The engine has a boiler, a cylinder and piston and operating valves.

Lime working and processing was carried out on the site from medieval times. Evidence of quarries and underground remains, the canal, and preserved lime kilns are parts of a scheduled ancient monument which has features from the medieval,
