On National Miller's Day, about 600 of the 1,000 existing windmills in the Netherlands open to the public. This holiday coincides with the Day of the cyclist, so visits to windmills are included in all cycling routes.
Windmills are one of the symbols of the Netherlands, along with canals, tulips, Dutch cheese and Dutch herring.
The Roman Pliny the Elder once said about the Dutch: “You don’t know whether they live on land or water.” In fact, the land here is unsteady, unreliable. Half of the territory of the state lies below sea level. The expulsion of water and the struggle for land suitable for life and agriculture is an everyday Dutch reality. The motto on the coat of arms of the Netherlands reads: “I fight and swim!”.
