Walking along the old walls, these are the breathtaking views you see of the surrounding countryside and coastline.
To get to the iconic postcard-like viewpoints overlooking Ostuni itself (in which you literally see the "White City"), you need to walk for a few minutes away from the historic center to Point to View Storico Centro (Corso Vittorio Emanuele II, 37) and Piazzetta Martiri delle Foibe - Belvedere di Ostuni (Corso Vittorio Emanuele II, 208).
