Dubrovnik - Fort Bokar, Late Afternoon
The sea walls of Dubrovnik stretches from Fort Bokar in the west to St. John Fortress in the south, and to the Revelin Frotress on the land-side. The walls measure from 1.5 to 5 meters thick, depending on their location and its strategic importance. These walls were built to defend the city from sea-based attacks, particularly from the Republic of Venice, which was then considered a threat to Dubrovnik.
Fort Bokar, also called Zvjezdan, was built as a two-story casemate fortress in the mid-15th century while the city walls were being reconstructed. It was conceived as the key point in the defense of the Pile Gate, the western fortified entrance of the city.
