German Mill Day in Ammerland 2026

Nationwide Day of Action in Ammerland

The German Mill Day has been celebrated annually on Whit Monday since 1994 and is the largest event for mill culture in Germany. In Ammerland, with its unusually high concentration of historic water and windmills, the day is firmly established in the event calendar.

2026 Edition on Whit Monday

The 2026 edition falls on Monday, May 25, 2026. Participating mills will open their doors to the public, millers will guide visitors through the grinding process, explain the waterwheel and millstones, and often offer fresh baked goods or regional products. The focal point in Ammerland is the Howiek watermill in Ocholt-Howiek, which directly follows the Pentecost festival of the previous day.

What Visitors Can Expect

The program at the individual mills follows a similar pattern: guided tours, demonstrations of the milling process, bread baking in stone ovens, small snacks with coffee and cake. Brass bands and folk musicians provide musical accompaniment in some places; children can often grind small bags of flour and take them home.

Ammerland, the Land of Mills

In Ammerland, besides the Howiek watermill, there are other historic facilities that regularly participate in Mill Day. The exact list of all open mills will be communicated shortly before the date by the local heritage associations and the tourism board. Mill Day is therefore a perfect opportunity for a Whit Monday tour through the rural Ammerland.
