Often you need to come back to a city to discover its hidden treasures. The Old Elbtunnel leading from St. Pauli to the Elbe Island Steinwerder is such a tucked away jewellery. For most Hamburgers it is just a way to get from A to B, but what a special one! Opened more than a century ago in 1911 the St. Pauli Elbtunnel serves as a public underwater thoroughfare for pedestrians, cyclists and – to a restricted amount – cars. Along the tiled walls of the 426,5 meters long tunnel you can find various stoneware reliefs illustrating fish, crabs, shells and other life forms of the massive river Elbe.
