Dubrovnik City Wall, south east
The city wall that surrounds the ancient city of Dubrovnik is a popular tourist attraction and can be walked in just over an hour. The main access point is via a steep flight of steps on the western side, just inside the city main entrance of Pile.
This view from the south eastern corner of the wall looks out over the ancient harbour, with the massive fortifications of St. John's Fort on the right hand side, guarding the main entrance.
