The 450 year-old Geestmolen (Ghost Windmill) is about 1 kilometer south-west along the Haut Vaart (Lumber Canal) from the Wognumsebuurt (Wognumse neighborhood or Woglums Burg), where the Roll family progenitor Jan Mangelsen and his spouse Tryntje Pieters Van Woggelum lived before emigrating to New Netherland.
The windmill is located in the modern day Hoefplan neighborhood of Alkmaar, North Holland. The 170 acre Geestmolen polder, part of a shallow inland freshwater lake named the Egmondermeer, was drained in 1562-1565 by three windmills that had to pump constantly to keep the new polder above water. One of them was the Geestmolen, a polder mill built in 1565 with an oak octagonal body on a low base. This type of mill is called a ground sailor and is located at Hoeverpad 13 in Alkmaar.
