Dubrovnik
Croatia
The walls are what stops you short. Pale limestone, blinding in July sun, enclosing a city so intact it feels theatrical. Inside, the Stradun is a marble runway worn glass-smooth by feet and time, flanked by cafes where a coffee costs three times what it does one street back. The Adriatic sits below everything, improbably blue, and cruise ships sit below that, blocking the view.
