Ostuni is a unique town that resembles a bright cap rising up right from the flat plains near the southern coast of Italy. Its whitewashed defensive walls and houses inside the old town with many winding streets, steps and beautifully decorated, colorful window frames can make you think you're somewhere in Greece. Although Ostuni is one of the main attractions in Puglia, it's less known than Polignano a Mare or Alberobello famous for its cone-shaped Truli houses. And the whole region of Puglia, in turn, is not as popular as, let's say, Tuscany but it's definitely not less worth a visit - so do include it in your itinerary to Italy - especially in the winter time.
