The Watermill at Opwetten (Dutch: Opwettense watermolen) is a watermill along the river Kleine Dommel, located on the Opwettenseweg 203 in Opwetten [nl], Nuenen, Gerwen en Nederwetten, in the province of North Brabant, Netherlands.

The gristmill is still in functioning order and is used on a small scale, the building of the former oil and fulling mill now houses a restaurant.

The gristmill was built in the early 11th century along the river Kleine Dommel,[1][2] by monks of a Benedictine monastery in Sint-Truiden, Belgium.

It was rebuilt and, in order to recover from the losses, the miller did not have to pay taxes for the next 15 years.

[4] In 1764 another fire destroyed the entire mill,[1][3] according to an ordenance from the States General after the miller requested assistance.

[5] The gristmill, originally used to grind spelt, later ground bread wheat, and then a sawmill was added.

Only some remainders are left of the sawmill, including one of only two watermill circular saws in the Netherlands.

Both structures are completely gone, and only two edge stones posted outside remind of its former function as oil mill.

The mill is located on the Opwettenseweg 203 in Nuenen, Gerwen en Nederwetten, in the province of North Brabant, Netherlands.
