National Mill Day 2025

The National Windmill Day, held annually on a weekend in May, is the perfect opportunity to admire hundreds of working windmills across the Netherlands up close. Since 1973, this event has celebrated our country’s rich windmill heritage and paid tribute to these iconic structures.
