Aumühle, Historical watermill in Moers, Germany.

The Aumühle, also called Obere Wassermühle, is a watermill complex in Moers consisting of the mill building erected in 1608–1609, a barn added in 1860, and a later annex by the Moersbach. The oldest part is used as a dwelling, the former barn as a studio, and the annex houses a working grinding mechanism that regularly produces bread. The water wheel is not operational because it is attached only to the mill pond, which follows the old course of the Moersbach.

The Aumühle's predecessor was a sluice that regulated water into Moers' city moat, flooding it and nearby fields to protect the town, as in the Thirty Years' War. First recorded as Vol mull (a fulling mill) on Johannes Mercator's 1591 map Murs Comitatus, it was rebuilt as a mill in 1608–1609. In 1612 it joined the Moers mill ordinance, which obliged surrounding farms to grind their bread grain there.

The name Aumühle comes from the popular nickname for the Vol mull, first recorded in 1591 as a fulling mill (Walkmühle) on Johannes Mercator's map. Under the 1612 Moers mill regulation, surrounding farms were forced to grind their bread grain here rather than use hand mills. Today the functional grinding works in the annex produces bread regularly, while the water wheel is not operational because it sits on the mill pond, which follows the old course of the Moersbach.

The site is easily accessible from Moers town center and sits close to the restored riverside. Since it is a private residence, it can only be viewed from the outside, though the architecture and water wheel are visible from the riverside path.

The water wheel visible today is not the original: the wheel taken from the demolished Beskesmühle in Niep was destroyed by pest infestation in 1988, removed in 1991 and replaced in 1992. The current wheel, built by SCI:Moers during the 2007–2011 restoration, does not turn, because the mill pond follows the old course of the Moersbach rather than the present one.
