Abandoned headstock of the immense coal mine Zeche Holland. The mine once boasted no less than six pits. The first pit opened in 1856 and closed approximately one century later, in 1963. The last active pit was closed in 1988. Except for this abandoned headstock, all other buildings have been torn down or redeveloped. The unique double Malakow tower of pit I & II was turned into housing whilst other machine rooms were reconverted into offices.
