There are around 1000 old fashioned windmills in the Netherlands according to the VisitHolland website. And as icons go, the windmills tend to steal the show.
Finding a windmill in the Netherlands is easy. You will spot them from the motorway, in the middle of many of the older cities and on location at the famous Kinderdijk. Getting inside one, however, is a little trickier. Luckily, on the second Saturday and Sunday of May, the Nationale Molendag allows you access to a large number of these historical power machines.
