I wonder why people in the 18th century needed to create liveable conditions of the swamps of Nederwaard, surely Europe wasn’t that crowded back then? But it is impressive: over 200 years ago people built 78 windmills to pump up water to live on the land – and in the mills. When driving to the site, one drives on sort of a ridge and can see how the sea level is higher than the land and the houses in the area.
It is free to walk in the area but a canal ride or a visit to the one of the windmills that is turned into a museum costs a few euros. In the museum one will see what life in a mill was like.
I thought the visitor centre was interesting and well done too. They had very illustrative ways to tell the story of the area, how they shut down many wind mills when the steam engines came. Nowadays the water is pumped up only with three engines.
