Robertsmühle in Mühltal was first mentioned in 1266. At the beginning of the 20th century, Robertsmühle was the first mill to cease grinding operations and instead became a boarding house and summer resort. After the political change, the mill stood empty for several years before the town of Eisenberg took over the site and the mill. Following renovation work, the Roberstmühle is once again used as a venue for events and a café is operated.
