Wijlre's old watermill is on of the most famous ones of its kind and its history goes back to the 13th century. It was first build as a "banmolen", a mill owned by the feudal lords where the locals where obliged to mill their grains. Together with the brewery, which was later sold off independently, and the adjoining farm, it belonged to the Lord of Wijlre. The mill has two wheels and it's a National Heritage Sight. The current buildings date from 1776, and some holiday apartments have been created in them. Although this originally was a mill for flour and oil production, the Molen van Otten has been used for small scale electricity production since the 1980's.
