The Sloten Windmill is a functioning draining mill and at the same time the only windmill in Amsterdam which is open daily to the public. The Mill is situated in the outskirts of Amsterdam not far from Schiphol Airport. It controls the water level in the western part of Amsterdam. This area is situated more than 2 meters below sea level. The Sloten Windmill is a rebuilt mill, dating from 1847. The whole year long the Mill can be visited daily (except Jan. 1st, April 27th and December 25 and 26). The windmill is a non-profit organisation, run by volunteers. Knowledgeable guides will gladly explain the working of the mill during a guided tour. And if possible the miller will demonstrate how the top of the mill is turned, or how to stop the mill.
