National Mills Day

National Mills Day 2023

On Saturday 13 and Sunday 14 May 2023, it is again Friends Lottery National Mills Day.

Every second Saturday (and Sunday) in May is ‘National Mill and Pumping Station Day’. An annual day since 1972 on which more than 600 wind and water mills and pumping stations are open to the public.

National Mills Day

Mills have played an important role in the development of our country for centuries. Not for nothing is the image of the mill iconic for the Netherlands. And even though mills have lost their economic function, they can still be admired turning in many places.

The ‘National Mills Days’ have been held every year since 1972. With the Mills Days, Vereniging De Hollandsche Molen wants to show that mills are vital; living monuments that deserve to be preserved. During the mills days, visitors can take a look inside a mill and mill owners and millers organise extra activities.

A public holiday in the Netherlands.

You can visit windmills in Haarlem too.

One of these is, of course, the Adriaan. This mill was built in 1779 on the foundation remains of the Goevrouwetoren tower, part of the medieval fortifications around Haarlem.

At this free event, you can visit mills across the country and get explanations on how the structures work. At some locations, you can also buy products made in the mill.
