History of Lady Bolles Water Tower
A Grade II Listed water tower restored approximately thirty five years ago (1980) this feature of the common served two purposes to my knowledge. Built on top of an emerging spring, the water was pumped to a reservoir in the upper part of the tower and was used to supply a near by iron works and to gravity feed water to Heath Old Hall. Sadly the restoration only encompassed the roof and brickwork, the interior is empty except for a couple of oak beams crossing the structure which would have supported floors. But you can still see the spring which emerges from the floor and seeps underground for a few meters before it appears outside the tower and runs to the nearby River Calder.
