There’s no better way to appreciate Dubrovnik’s history and architecture than by traversing the beautiful walls that surround the Old Town. There are multiple entrances, but the best (and most popular) is on the left side of Stradun, just after you enter the city from the
Pile Gate (which is topped by a large Croatian flag.) Entrance costs 30Kn (students 20Kn, children 10Kn) and it’s a good idea to bring something to drink as the two-kilometer circuit contains many steps and can get quite tiring, particularly in hot weather.
The walls offer outstanding views into the Old Town and its red-tiled roofs, the Old Port (and the nearby island of Lokrum), and out to sea, but are also quite a sight unto themselves. For all their present harmony, they were actually constructed and expanded over the course of four centuries (from the 1200s to the 1600s) and their sixteen towers reflect a variety of architectural styles. Many individual fortifications, such as the Pile Gate (which is mentioned in sources as early as 972 but which was reinforced in 1461) are even older.
Almost directly opposite the Pile Gate, on a headland near the city, is the one piece of Dubrovnik’s historic fortifications not linked to the city walls, the Fortress of Lovrijenac, which according to legend was constructed in a mere three months in the early 11th century to prevent the Venetians from building their own fortress there. Above the entrance, the defiant Ragusans inscribed "Non bene pro toto libertas venditur auro" ("All the gold in the world cannot buy freedom.")
The Ragusan did spend a great deal of gold preserving freedom themselves, however, and the most elaborate of the fortifications date to the Republic’s Renaissance peak. The largest and most impressive of these is the Minčeta Fortress which resembles a large chess piece. Begun by the Florentine Michelozzo Michelozzi in 1455 on the site of a medieval quadrangle, and completed by Juraj Dalmatinac (the greatest architect of the Croatian Renaissance), it guards the northwest corner of the city, the most obvious route of attack by land. Hard up against the eastern edge of the landward portion of the walls is the Dominican Monastery, built in the early 1300s with civic assistance because of its important role as a fortification.
Just beyond the Monastery is the Ploče Gate, further defended by the Revelin Fortress just outside the walls. Work on both commenced in 1449, although it took until 1539 for the Revelin to be completed. Together with St. John’s Fortress, at the southeast corner of the city, the Revelin defended the harbor. However they were of little use when the Serbian gunboats shelled the harbor in 1991, damage from which is still evident just inside the city’s eastern wall. The seaward southern wall is of more interest for the spectacular views (and photograph opportunities) it offers than its history, although the Michelozzi-designed Bokar Fortress at its western end is a very attractive example of a casemate fort.
