The Pfuhlbrückenmühle (hemp sack mill) was first mentioned in 1250, making it the oldest inner city mill in the town. It was used as a grinding and tan mill. It was damaged in a town fire in 1487 and burned down completely in a fire in 1660.

In 1665, it was rebuilt as a hemp sack mill. It burned down again in the town fire of 1689 and was subsequently rebuilt. A steam boiler was installed in 1876. In 1890, the mill was shut down and partially demolished. In 1984, a fire destroyed the rest of the building. Today, a bridge can be found on the former site.
