Frost still lingers on the grass on this cold day, where ducks rest in the pasture.The Obdammermolen is an octagonal binnenkruier (inside-rotating) windmill, likely built in the last quarter of the 17th century. Generally, 1698 is considered its construction year. Together with a pumping station, it drained the 905 hectares large Obdam polder on the Vereenigde Raaksmaats and Niedorperkoggeboezem.
