Gengenbach had a town wall around the whole city and the abbey. After the destruction of the town in 1689, though, most of it was demolished, taken down or used as foundations to build houses on like in Engelgasse. A stretch of town wall with allure is preserved in Benedikt-von-Nursia-Straße behind the abbey grounds.Three big towers and torsos of three small towers have remained of the imperial city's fortification.Kinzigtor, as the name indicates, leads to Kinzig river and the bridge. The tallest of the three fortification towers is close to the railway line and easy to spot from the train. Into town, the gate leads straight to the main square and to the city hall which can be spotted through the arch. The pointed ends of the portcullis look rather threatening.
