Until 1885 the inhabitants of Den Bosch depended on surface water or wells and pumps for their drinking water. When this 33m high tower, designed by architect J. Kalff, was erected, the town was finally provided with a modern water supply system. Indeed, the two water reservoirs measuring 180m2 were unique at the time. Since 1974 this remarkable building has had national monument status and has housed several different organisations, including a shelter for the homeless and a boxing training centre.
