("The North") in Schiedam, Netherlands was the tallest windmill in the world ...
... until, close to it, the De Nolet
was built in 2006, a wind turbine which resembles a traditional Schiedam windmill.
As said: the tallest windmill in world is actually a disguise because hidden inside of the windmill’s 43-meter-tall tower is a wind power station. Operated by the >Nolet Distillery<
, Noletmolen in Schiedam, South Holland, measures 55 meters at the top of the rotor, making it the tallest in the world.
But since this isn't a real windmill because of the way the structure is being used, the tallest still is De Noord with a roof height of 33.3 meters.
Interesting website about De Nolet wind turbine
, with a lot of details about how the stones were produced.
