Leicester's former sewage pumping station is now a museum of science, technology, and industrial history — and one of the more eccentric attractions in the city. The Victorian Gothic building houses four massive Gimson beam engines, each standing several storeys high, and on special "steaming weekends" they are fired up and run for the public.
The wider collection covers Leicester's industrial heritage and includes a narrow-gauge railway that operates on open days. Even on non-steaming days the building is worth visiting: the engines are impressive objects even standing still, and the displays on Victorian sanitation and public health are surprisingly engaging. Check the events calendar before visiting if you want to see the engines in action.
