From the outside you may wonder what it has to offer, perhaps even think it is just for the pure mine enthusiast. How wrong you would be. Inside the building it is impressive, with a wide range of displays and working models. Volunteers take you on a tour of the remains of the outside pump site and a full guided tour around the building. The bonus is the wonderful collection of old Thames photographs that adorn several side rooms - these alone make the visit worthwhile.
