History
Watermolen, Testelt is a historic watermill in Belgium, on the Demer at Testelt in Scherpenheuvel-Zichem. Also known as the Abbey Mill, it was probably already operating before 1150 and is regarded as one of the oldest mills in the region. In 1151, Zeger, lord of Testelt, transferred the milling rights and the land beneath the mill to Averbode Abbey, a religious abbey founded in 1134. The transfer made the mill an ecclesiastical economic asset and placed its operation under the abbey’s authority.
Medieval Milling Complex
The original grain mill stood on the left bank of the Demer, on the Messelbroek side. An oil mill was added on the opposite bank in 1264, creating a complex that used both sides of the river. The mill’s history was therefore tied to the control of water, land, and the right to process grain and oilseed for the surrounding community.
Expansion and Destruction
A proposed sale to Willem van Croy, Margrave of Aarschot, a high-ranking nobleman associated with the margraviate of Aarschot, fell through in 1520. During the sixteenth century, the complex expanded across the Demer. By the end of that century, it had also become part of a military fortification. Spanish troops burned the fortification in 1598, and the mill was rebuilt ten years later, in 1608.
Abbey Lease and Mill Duties
Averbode Abbey leased the mill to an operator. The 1771 contract set the rent at 600 guilders for four years and required the miller to supply 50 mud of good-quality grain each year, delivered quarterly. The oil mill carried additional obligations, including two aams of rapeseed malt, 100 rapeseed cakes, and six portions of eels. These were period measures whose exact capacities varied by place and time. Rapeseed cakes were the pressed remnants of oilseed processing.
Grain belonging to the abbey, including wheat, rye, buckwheat, and oats, was milled without charge, and the abbot retained priority when grain was processed. If the mill stopped for more than three months, the miller was entitled to compensation. Milling was forbidden on Sundays and feast days, while gatherings of young women or men were prohibited inside the building.
The miller maintained the business buildings, the mill sluice, and the operation of the mill. The abbot supplied the necessary timber, iron, and stone. The miller also had to open the sluice at specified times so that navigation remained possible and nearby land was not flooded at unsuitable times. Further annual payments to the church of Testelt consisted of two mud of rye, six halsters of wheat, an aam of linseed oil for the church lamp, one aam of rapeseed malt, 100 rapeseed cakes, and 25 eels.
Ownership, Decline, and Restoration
The mill became the property of the Theyskens family of Testelt in the early nineteenth century. The oil mill on the left bank was demolished in 1910 to make way for Villa ter Wolf. The remaining grain mill was sold to the miller Victor van Aelst in 1928. The Belgian state acquired it in 1952, followed by restoration work during the 1960s.
The building later deteriorated and became a ruin. During the 1990s, Hervé Segers of Duffel acquired the mill and carried out a thorough restoration. The work included installing a new waterwheel and excavating a channel toward the Demer. The mill house served for a long period as a banquet and events hall and is also identified as a grain mill and events venue.
Water-management works in the 1960s brought a major threat to the building. The Belgian state demolished the weir in the Demer, lowering the water level beside the mill arm, a branch or diverted channel used to supply the mill. The arm subsequently dried out, endangering the building’s stability. In 2019, Segers had a concrete slab poured, but the heritage agency halted the intervention. In 2021, the municipal executive of Scherpenheuvel-Zichem authorized remedial work and decided that the alterations should be reversed.
Since 23 October 1981, Watermolen, Testelt has been protected as a monument and has formed part of the protected villagescape of Testelt village centre. A protected villagescape is a legally designated historic village area whose built character and appearance receive heritage protection. The mill was also recorded as architectural heritage on 14 September 2009.
Remains
The surviving site is centered on the longitudinal mill building on the right bank of the Demer. The former complex once extended across the river, but the left-bank oil mill was demolished in 1910. The remaining structure combines local iron sandstone, brick, and sandstone, while its water-powered machinery is associated with the mill sluice and the diverted mill arm of the river.
Mill Building
Stonework and Entrance
The lower part of the building, including the front and side facades, is constructed mainly from local iron sandstone. This sandstone contains iron compounds that commonly produce reddish or brown tones. The entrance is framed by a white-sandstone basket-handle arch, a shallow, smoothly curved arch resembling the shape of a basket handle.
Above the entrance is a stone bearing the coat of arms of Servaes Vaes, an abbot of Averbode Abbey. It also carries the motto ne quid nimis, meaning “nothing in excess,” and the date 1678. The stone provides a later historical marker within the rebuilt and altered mill structure.
Southern and Northern Facades
The southern facade stands beside the mill sluice. It uses brick and sandstone in a simple traditional design, with traces of alternating horizontal bands of stone and brick. The northern gable preserves the date 1608, formed in dark brick and masonry marks. That date identifies the rebuilding that followed the burning of the fortification by Spanish troops in 1598.
Water System
Undershot Waterwheel
Watermolen, Testelt is an undershot watermill on the Demer. In this system, water strikes the lower part of the wheel rather than passing over its top. A new waterwheel was installed during the restoration of the 1990s.
Mill Sluice and Mill Arm
The waterwheel is linked to a mill sluice, a controllable gate that regulates the water serving the mill while also helping manage navigation and flooding. The site is also connected with a mill arm of the Demer. A channel was excavated toward the river during the later restoration, while the earlier lowering and drying of the mill arm had threatened the stability of the mill building.
