In 1883, Hamburg knocked down a whole neighbourhood.
More than 20,000 people lost their homes - and in their place the city built warehouses.
Not a few: a mile and a half of red brick, seven storeys high, with canals running between them so barges could unload straight into the buildings.
It is called the Speicherstadt, and it is the largest warehouse district in the world.
Here is the strange part. There is no solid ground underneath it. The whole thing stands on thousands of oak tree trunks hammered down into the mud.
Hamburg was once a major harbor city, and coffee, cocoa, spices - and at one point a third of the world’s carpets - passed through these streets. |
