“De Twiskemolen” (Twiske-mill) is an octagonal binnenkruier (windmill of which the inside works is movable), build around 1578. In 1973-1974 it was put on its current place and since then it is put in operation regularly to drain the 650 hectare large Twiske-polder with its mortar, as under-draining of the polder Oostzaan. The mill stood in Barsingerhorn till the sixties of the last century (20^th), where it drained the Hooglandspolder for a long time.
