Following the riverside footpath from the city center, the first thing you notice about the Cambridge Museum of Technology is its tall chimney. Housed in a Victorian pumping station, the museum holds an array of old steam engines, gas engines, boilers and printing presses. These machines are brought back to life on steam days when the pumping station is a cacophony of whirls and whistles or creaks and groans. Steam days are held eight times per year. So do contact for more details.
