The Molzmühle is located today on the Mühlenbach stream, whose estuary was altered in 1966. Due to the increasing risk of flooding in Wegberg, the Schwalm river was regulated from the sewage treatment plant to the Molzmühle and diverted by 40 meters at the Molzmühle. Since then, the Mühlenbach has been the only water source to the Molzmühle. The owner was compensated for the loss of the Schwalm water and the dam rights.
The mill received its name from one of its owners. A lease deed from 1627 lists Arnold Molz as the owner. At the beginning of the 19th century, the mill was powered by an undershot waterwheel. Because the Schwalm, in conjunction with the Mühlenbach, carried abundant water, two grinding mills and an oil press could be operated. In 1853, Wilhelm Josef Brinkmann became the tenant of the Molzmühle for almost 40 years. Under his direction, the mill operated for up to 16 hours a day. From 1913 onward, it is recorded that a second source of income was the catching and selling of eels. The eels were caught in crates placed in front of the mill wheel. The proceeds paid the entire annual rent of 1,400 marks. In 1926, a widow named Gripekoven was granted permission to operate a pub. Milling operations ceased in 1930, and the mill has been run as a guesthouse ever since.
Today, the mill houses a hotel and restaurant serving Alsatian-inspired cuisine.
