"What's a "sense of history" anyway? Old buildings?
Precisely. Old buildings, old neighborhoods, etc. That's what makes Europe different from North America.
"Which place has a bigger "sense of history", Berlin or Cesky Krumlov? Berlin was almost completely leveled in WW2, but is full of memorials, museums, plagues and things like preserved bullet holes or graffiti of Russian soldiers
Museums and memorials are not history. They are not sense of place. A museum is just buildings full of stuff taken from its natural setting. I might be willing to travel to Hisarlik but I'm not going to travel to Berlin just to see Agammenon's mask. Memorials are boring. Just plain boring. Gushing, maudlin monuments to victimhood. Never seen one I'd walk cross the street for.
"the vibe of the city, which is best described by a quote from 1910: "Berlin is a city condemned forever to becoming and never to being."
That city no longer exists. It was bombed flat.
"the best DÖNER KEBAB!"
That certainly is good enough reason to travel several thousand miles.
"Potsdam, the summer residence of the Prussian kings, which is a city surrounded by lakes, parks, castles and palaces (exactly what you are looking for, and much more than just Sanssouci) the sights in the surroundings, like Wittenberg (Luther), the Spreewald, Schwerin (fairytale castle) or Leipzig (Bach), which you can see on day trips the many sights in the region, which you could see on a tour starting in Berlin (Germany is much more than just Bavaria)"
No you're talking. This sounds much better. I'll check them out.
