Old and New Town, Warsaw
Concierge.com's insider take:
Warsaw's Old Town is one of Europe's most extraordinary feats of reconstruction. The Old Town wasn't just badly damaged—it was deliberately obliterated by the Nazis, who knew how much it meant to patriotic Poles. The Nowe Miasto (New Town) to the north, beyond the medieval city walls, is just as picturesque, but with a fraction of the tourist traffic. Like Edinburgh's New Town, it's not new at all, merely neoclassical rather than Renaissance.
