Ampelentower
The Gerberbach in the open moat
The road under the bridge, Bachstrasse, was once a stream, the Gerberbach, which flowed through the town’s moat. The medieval town wall turned to the east here, spanning the stream and thus linking the fortress on the hill to the ring-shaped town wall.
The stream passage was secured by an iron gate and a tower, wich was called “Ampelenturm”.
