Banmolen

Banmolen is a historic watermill on the Kleine Nete river, near the village of Grobbendonk in Belgium's Antwerp province. It stands right where the Kleine Nete meets the smaller Aa stream, at Watermolenweg 1, and is regarded as one of the finest undershot mills in the Kempen region. It's also known locally as Molen van Hool, after the family that once ran it.

How old is this mill?

Traces of a watermill on this exact spot go back to before the year 1100 — the earliest known structure here already harnessed the Kleine Nete's current to grind grain. A surviving charter from March 1254 settled an ownership dispute over the mill, evidence of just how economically important it already was in the Middle Ages. Its history was far from peaceful, though: the mill burned down in 1268 and was rebuilt, then was destroyed again in 1579 and restored once more. The former oil mill building, still standing on the river's right bank, dates from that 1579 rebuilding.

What does the name "banmolen" actually mean?

The name isn't incidental. A banmolen was a compulsory mill — a facility that every resident of a given lordship was legally required to use for grinding their grain, rather than being free to choose elsewhere. This was a standard feature of the medieval and early modern feudal system, letting the local lord collect steady revenue from a milling monopoly across his territory. Grobbendonk's banmolen was no exception, remaining a central hub of the region's agricultural economy for centuries.

What jobs did the mill actually do?

The Banmolen wasn't limited to a single purpose. Its main role was grinding grain (a korenmolen), but for part of its history it also operated as an oil mill (oliemolen), pressing oil from oilseeds. Between 1620 and the end of the 17th century, the oil mill building additionally housed fulling equipment (volmolen), used to felt and thicken woollen cloth. This kind of multi-purpose setup was typical of important watermills of the era, which needed to squeeze maximum value out of the available water power.

How did it survive turbulent times?

The year 1795 was a dramatic one for Grobbendonk: French troops set fire to the nearby Kasteel Grobbendonk. The Banmolen, owned at the time by the lords of Grobbendonk, escaped that destruction and kept operating in the decades that followed. By 1870, the mill still had three waterwheels — one driving the oil mill, and two powering the grain-milling side. That technical setup reflects just how significant the site was to the local 19th-century economy.

Is the mill still working?

Yes — the Banmolen is one of the few historic Belgian watermills that still grinds grain daily, powered by the Kleine Nete's flow. That makes it more than an industrial heritage landmark: it's a living demonstration of centuries-old milling technology, still functioning in essentially its original form.
