Still, the sights were something to see, so sightseeing I did.
I actually wondered if I ever walked through it before or not. This time, I did.
Reichstag (no, I didn't get inside. You have to reserve well in advanced)
Denkmal für die ermordeten Juden Europas (or, short, the Holocaust-Memorial)
In the Pergamonmuseum, the Market Gate of Miletus
One of the lions on the wall of the Gates of Babylon. The colors and details of those is absolutely amazing.
And finally (but certainly not least), a very different tower … A Ritter Sport Chocolate Tower (though, to be honest, this is only a mock up, but one can wish … and, I think there was enough chocolate in that place to make it real)
I haven't seen half of what I wanted to see and done half of what I wanted to do, so I guess another visit to Berlin will happen soon(ish)
