Near the quays where the ferries dock, the "Landungsbrücken", stands the building housing the entrance to the old tunnel which runs underneath the river Elbe. It was opened in 1911. The classicist style of the brown sandstone square building, with its cupola and tall windows, is reminiscent of the Pantheon in Rome. A much simpler version stands at the other end of the tunnel on island of Steinwerder where the docks are. Escalators, stairs and elevators (for vehicles) descend to two parallel-running tunnels which are 410 metres long. Hundreds of light bulbs on both sides are reflected in the tunnels" tiled walls decorated with maritime motifs.
