St. Pauli Elbe Tunnel, which opened in 1911, is a pedestrian and vehicle tunnel. The 426 m (1,398 ft) long tunnel was a technical sensation; 24 m (80 ft) beneath the surface, two 6 m (20 ft) diameter tubes connect central Hamburg with the docks and shipyards on the south side of the river Elbe. This was a big improvement for tens of thousands of workers in one of the busiest harbors in the world.

Four huge lifts on either side of the tunnel carried pedestrians, carriages, and motor vehicles to the bottom. The two tunnels are both still in operation, though due to their limited capacity by today's standards, other bridges and tunnels have been built and taken over most of the traffic.  [Wikipedia]

 

 

These are the stairs to get down to the tunnel (or you can use the lifts).

These are the lifts.

 

They are huge inside!

 

The Speicherstadt (warehouse district) is the largest in the world where the buildings stand on timber-pile foundations of oak logs.  It is located in the port of Hamburg and was built from 1883 to 1927.  The district was built as a free zone to transfer goods without paying customs.  It is 1.5 km (0.93 mi) long and interlaced by loading canals.  [Wikipedia]
