Speicherstadt and Kontorhaus District by Tom Livesey
It looks like I am the first reviewer to have visit this site since it was inscribed and I can report that I didn't spy a UNESCO logo or information board anywhere (though that doesn't mean there isn't one). I spent a night in Hamburg in January 2017 and stayed in a waterfront hotel in the inscribed area.
The warehouses, which display a definite coherence of style, stand testament to the development of large-scale international trade in the wake of the Industrial Revolution.
My overall impression was of a pleasant enough place but not a terribly exciting World Heritage Site compared with others. Of the 105 I have so far visited it is most similar to Liverpool.
