Kalfmolen

Kalfmolen is a wooden post mill standing on the Graaf Jansdijk dike, in the Het Kalf district right next to Het Zoute, in the municipality of Knokke-Heist. Like all post mills, its entire body pivots around a central post so it can be turned to face whichever direction the wind is blowing — a design typical of the oldest windmills in this part of Flanders.

Where does the name come from?

The mill takes its name from the nearby inn "Het Kalf." Together, the mill and the inn gave their name to the surrounding neighborhood during the 19th century — before that, the area was known as Oosthoek. Today "Het Kalf" still refers to this pocket bordering the upscale Het Zoute district.

How old is the Kalfmolen?

The earliest written record of the mill dates from 1681, though the structure itself is believed to be older — it was likely built around 1670 on the Graaf Jansdijk, a sea dike dating back to the early 15th century. From the start, it operated as a grain mill.

What happened to it during the 20th century?

The mill fell silent during World War I and gradually deteriorated. It was restored in 1924–1925 and put back into operation in 1926, but commercial milling ended for good in 1927. In 1939, the Kalfmolen became the first Belgian windmill to receive legal protection, under the law of August 7, 1931 on the preservation of monuments and landscapes.

The municipality of Knokke took ownership in 1974 and commissioned an extensive restoration carried out in 1979–1980 by the contractor Cottenier from Aalbeke, based on a design by architect Walter Snauwaert from Ostend.

What is there to see inside?

The mill has two floors: a grinding floor and a millstone floor. The millstone floor holds two pairs of millstones, while the grinding floor houses an oat flattener. After years of neglect through two world wars, the Kalfmolen once again functions as a working wooden windmill — when it isn't grinding, its enthusiast millers take visitors inside to explore the mechanism firsthand.

Can visitors go inside?

The Kalfmolen occasionally opens to the public during events such as Open Monumentendag (Open Monuments Day), when it and the nearby Molen van Callant both open their doors together. These are rare chances to see the mill's mechanism turning from the inside and talk to the people who keep it running.

Frequently asked questions

Does the Kalfmolen still grind grain? Regular commercial milling ended in 1927, but the mechanism is kept in working order and occasionally set in motion for demonstrations.

Where exactly does the mill stand? On the Graaf Jansdijk dike, in the Het Kalf district, right next to Het Zoute in the municipality of Knokke-Heist.

What makes a post mill different from other windmill types? In a post mill, the entire body of the mill rotates around a central post, rather than just the cap — making it one of the oldest windmill designs in Western Europe.
