Old powerhouse
The 19th-century power plant, near the old city castle, provided hydroelectric power for the city's many textile mills. It was later home to a discotheque, which has subsequently closed due to neighborhood complaints, but guided tours can still be made by special arrangement.

The former city castle (first mentioned in the 10th century!) is now the seat of the district courthouse, but is still beautiful in its own right, with its imposing 46-m spire springing from the peak of the castle hill. The castle grounds feature a waterfall on the back side of the hill.
