The Breustermolen is a working watermill mill located on Kapelkesstraat in the town of Eijsden. There were originally five watermills located on the river, however two of them have been demolished. The Breustermolen was built in 1788. The Breustermolen was originally used as a corn mill, but was converted to an electricity generator in 1986, as part of a trial of hydroelectric power services. The results of the trial were poor, and the mill has been idle since 1989.
