Beautiful windmill on the heath of Gijmel and Langdorp. The windmill has been very well preserved because it has never been destroyed or burned down. This is a good place to rest for a while, as there are several benches here.

The Heimolen is a post mill dating from 1662, located on Windmolenstraat in Gijmel/Langdorp, Aarschot, and is owned by Natuurpunt. It is one of the last 130 wooden windmills remaining in Flanders. What makes it special is that it has remained in the same location since its inception and has never been destroyed by fire or war. The current structure of the Heimolen is almost entirely original. The fact that the mill has never been thoroughly renovated is evident not only from inscriptions inside the mill but also from various historical documents. Moreover, the mill itself reveals its origins: it is one of the very few windmills with a straight chapel roof – after 1700, curved chapel roofs were common everywhere. The mill is open to the public: All year round, every 2nd and 4th Sunday from 10:00 AM to 1:00 PM. The mill is open on these days, but not in operation. During these hours, visits and tours of the Heimolen are free. For tours outside of these hours, you can make an appointment with one of the volunteers. A fee of €2 per person is charged, with a minimum of €50. To schedule a visit, please contact: Bert: 0476/23 27 90 Luc: 016/50 12 13
