Friedberg watchtower was erected in 1478 as a protection and observation point for the new settlements in the northern part of the town. From here, the watchman could see the surrounding area and, if necessary, give a warning signal to the town by flag or torch. In 1634 the tower was destroyed by fire, but was rebuilt just a few years later. It managed to survive the Second World War without any major damage and is now home to a traditional pub, famous for its apple wine.
