Ondermolen O

Ondermolen O is a historic polder mill that was originally built around 1633to drain part of the Schermer. Once the Schermeer started to dry up, a major rearrangement of the existing mills took place. This mill was therefore moved to its current location in 1652, to serve as a lower mill and be part of a group of sixteen mills between Ursem and Schermerhorn. (Ursem Gem Schermer, Netherlands)
