Mill "De Onrust"
The "De Onrust" windmill was built in 1809 to drain the Naardermeer. The 15-meter high mill controls the water level of this nearly 700-hectare swamp area, without the support of another pumping station.
The scoop wheel moves approximately 10 m³ of water per revolution. For this the wick cross turns twice. To achieve a level reduction of 1 cm, one day (approximately 16 hours) with good wind is needed.
