Old City: Place Zamkowy, Barbican, Restaurant Bazyliszek, Pomnik Syrenki, Galeria Polskiego Plakan, Rynek Starego Niasta, Zamek Krolweski, Mury Obronne. Warsaw, Poland.
I was only in Warsaw for 4 hours, but I saw everything on this postcard. Cool, heh? (yeah, I am a good backpacker:D)
Also, how sweet is it that the amblem of the city being a mermaid (with a sword though!)
