The property is part of The Essex and Suffolk Water Company where the old steam pumping station is now used for the Museum Of Power. ‘Marshall’, the 1931 Lilleshall Pumping Engine No. 282, currently run on compressed air, is believed to be the only working example of a Lilleshall Triple Expansion steam engine in the world.
Set in seven acres of grounds with the River Blackwater running through, the main exhibits are housed in the 1920s Steam Pumping Station, the former generator hall and boiler house, with many working examples of various power sources, machinery, equipment and tools.
Outside in the grounds more attractions can be found including a model village, picnic area and the ever-popular ‘miniature railway’.
