0019 - Tide

This one's from Germany. The sender didn't elaborate anything on the view, so I'm not sure where this one particularly is. :(

Anyone care to enlighten?

0004 - Hamburg

Hamburg's a big town in Germany and those 4 pictures above are some of their landmarks.

Clockwise starting from left:

1) Heinrich Hertz TV Tower - This tower stands at about meters and there's a revolving restaurant at the top as well! :)

2) Not sure if this is the flag of Hamburg.. Someone enlighten me?

3) Couldn't find any info on this one.. Help!!

4) Speicherstadt - These are warehouses situated in the free port area of Hamburg.
