The square was redesigned after the fire of 1842. It is dominated by the campanile of the Renaissance Town Hall (1897). The bridge crosses the Alsterfleet, the remains of the canal system in old Hamburg. It is close to the lock that maintains the level of the Alster. Don't miss the work by Barlach situated at the head of the bridge - a high stele of the monument to the Dead of the First World War.
