Water is the essence of Kvarner, and the region's largest city expresses this simply. Whether in Croatian or Italian (Fiume) the translation of the name to English is the same: river. Although the history of Croatia's third city goes back to the days of Imperial Rome, modern Rijeka evolved under the rule of Austria-Hungary. The historic core retains vestiges of the old Habsburg monarchy from the time when Rijeka served as the empire's outlet to the Adriatic. During the 1960s, under Yugoslavia, the suburbs expanded rapidly. Rijeka is the country's largest port, with a huge shipyard, massive dry-dock facilities, refineries, and other heavy industries offering large-scale employment. Since the breakup of Yugoslavia, however, Rijeka's role as a shipping town has declined significantly. Much business shifted north to the smaller Slovene ports during the crippling wars of the 1990s, and although some has returned, the volume remains less than half that seen in 1980.

Dalmatia's capital for more than 1,000 years, Zadar is all too often passed over by travelers on their way to Split or Dubrovnik. What they miss out on is a city of more than 73,000 that is remarkably lovely and lively despite—and, in some measure, because of—its tumultuous history. The Old Town, separated from the rest of the city on a peninsula some 4 km (2½ miles) long and just 1,640 feet wide, is bustling and beautiful: the marble pedestrian streets are replete with Roman ruins, medieval churches, palaces, museums, archives, and libraries. Parts of the new town are comparatively dreary, a testament to what a world war followed by decades of communism, not to mention a civil war, can do to the architecture of a city that is 3,000 years old. A settlement had already existed on the site of the present-day city for some 2,000 years when Rome finally conquered Zadar in the 1st century BC; the foundations of the forum can be seen today. Before the Romans came the Liburnians had made it a key center for trade with the Greeks and Romans for 800 years. In the 3rd century BC the Romans began to seriously pester the Liburnians, but required two centuries to bring the area under their control. During the Byzantine era, Zadar became the capital of Dalmatia, and this period saw the construction of its most famous church, the 9th-century St. Donat's Basilica. It remained the region's foremost city through the ensuing centuries. The city then experienced successive onslaughts and occupations—both long and short—by the Osogoths, the Croatian-Hungarian kings, the Venetians, the Turks, the Habsburgs, the French, the Habsburgs again, and finally the Italians before becoming part of Yugoslavia and, in 1991, the independent republic of Croatia. Zadar was for centuries an Italian-speaking city, and Italian is still spoken widely, especially by older people. Indeed, it was ceded to Italy in 1921 under the Treaty of Rapallo (and reverted to its Italian name of Zara). Its occupation by the Germans from 1943 led to intense bombing by the Allies during World War II, which left most of the city in ruins. Zadar became part of Tito's Yugoslavia in 1947, prompting many Italian residents to leave. Zadar's most recent ravages occurred during a three-month siege by Serb forces and months more of bombardment during the Croatian-Serbian war between 1991 and 1995. But you'd be hard-pressed to find outward signs of this today in what is a city to behold. There are helpful interpretive signs in English all around the Old Town, so you certainly won't feel lost when trying to make sense of the wide variety of architectural sites you might otherwise pass by with only a cursory look.

Nothing can prepare you for your first sight of Dubrovnik. Lying 216 km (135 miles) southeast of Split and commanding a jaw-dropping coastal location, it is one of the world's most beautiful fortified cities. Its massive stone ramparts and fortress towers curve around a tiny harbor, enclosing graduated ridges of sun-bleached orange-tiled roofs, copper domes, and elegant bell towers. Your imagination will run wild picturing what it looked like seven centuries ago when the walls were built, without any suburbs or highways around it, just this magnificent stone city rising out of the sea.In the 7th century AD, residents of the Roman city Epidaurum (now Cavtat) fled the Avars and Slavs of the north and founded a new settlement on a small rocky island, which they named Laus, and later Ragusa. On the mainland hillside opposite the island, the Slav settlement called Dubrovnik grew up. In the 12th century the narrow channel separating the two settlements was filled in (now the main street through the Old Town, called Stradun), and Ragusa and Dubrovnik became one. The city was surrounded by defensive walls during the 13th century, and these were reinforced with towers and bastions in the late 15th century.From 1358 to 1808 the city thrived as a powerful and remarkably sophisticated independent republic, reaching its golden age during the 16th century. In 1667 many of its splendid Gothic and Renaissance buildings were destroyed by an earthquake. The defensive walls survived the disaster, and the city was rebuilt in baroque style.Dubrovnik lost its independence to Napoléon in 1808, and in 1815 passed to Austria-Hungary. During the 20th century, as part of Yugoslavia, the city became a popular tourist destination, and in 1979 it was listed as a UNESCO World Heritage Site. During the war for independence, it came under heavy siege. Thanks to careful restoration, few traces of damage remain; however, there are maps inside the Pile and Ploče Gates illustrating the points around the city where damage was done. It’s only when you experience Dubrovnik yourself that you can understand what a treasure the world nearly lost

Bari, capital of the province of Apulia, lies on southern Italy's Adriatic coast. Its busy port is a leading commercial and industrial centre as well as a transit point for travellers catching ferries across the Adriatic to Greece. Bari comprises a new and an old town. To the north, on a promontory between the old and new harbours, lies the picturesque old town, or Citta Vecchia, with a maze of narrow, crooked streets. To the south is the spacious and regularly planned new town, which has developed considerably since 1930, when the Levant Fair was first held here. The heart of the modern town is Piazza della Liberta. The busy thoroughfare, Corso Vittorio Emanuele II, separates the new town from the old. At the eastern end of the Corso begins the Lungomare Nazario Sauro, a magnificent seafront promenade that runs along the old harbour. Bari and the Apulian region were long recognized for their strategic location, attracting a succession of colonizers such as the Normans, Moors and Spaniards, each leaving their mark. 

Backed by imposing mountains, tiny Kotor lies hidden from the open sea, tucked into the deepest channel of the Bokor Kotorska (Kotor Bay), which is Europe's most southerly fjord. To many, this town is more charming than its sister UNESCO World Heritage Site, Dubrovnik, retaining more authenticity, but with fewer tourists and spared the war damage and subsequent rebuilding which has given Dubrovnik something of a Disney feel.Kotor's medieval Stari Grad (Old Town) is enclosed within well-preserved defensive walls built between the 9th and 18th centuries and is presided over by a proud hilltop fortress. Within the walls, a labyrinth of winding cobbled streets leads through a series of splendid paved piazzas, rimmed by centuries-old stone buildings. The squares are now haunted by strains from buskers but although many now house trendy cafés and chic boutiques, directions are still given medieval-style by reference to the town’s landmark churches.In the Middle Ages, as Serbia's chief port, Kotor was an important economic and cultural center with its own highly regarded schools of stonemasonry and iconography. From 1391 to 1420 it was an independent city-republic and later, it spent periods under Venetian, Austrian, and French rule, though it was undoubtedly the Venetians who left the strongest impression on the city's architecture. Since the breakup of Yugoslavia, some 70% of the stone buildings in the romantic Old Town have been snapped up by foreigners, mostly Brits and Russians. Porto Montenegro, a new marina designed to accommodate some of the world’s largest super yachts, opened in nearby Tivat in 2011, and along the bay are other charming seaside villages, all with better views of the bay than the vista from Kotor itself where the waterside is congested with cruise ships and yachts. Try sleepy Muo or the settlement of Prčanj in one direction around the bay, or Perast and the Roman mosaics of Risan in the other direction.

It's no wonder that all roads lead to the fascinating and maddening metropolis of Athens. Lift your eyes 200 feet above the city to the Parthenon, its honey-color marble columns rising from a massive limestone base, and you behold architectural perfection that has not been surpassed in 2,500 years. But, today, this shrine of classical form dominates a 21st-century boomtown. To experience Athens—Athína in Greek—fully is to understand the essence of Greece: ancient monuments surviving in a sea of cement, startling beauty amid the squalor, tradition juxtaposed with modernity. Locals depend on humor and flexibility to deal with the chaos; you should do the same. The rewards are immense. Although Athens covers a huge area, the major landmarks of the ancient Greek, Roman, and Byzantine periods are close to the modern city center. You can easily walk from the Acropolis to many other key sites, taking time to browse in shops and relax in cafés and tavernas along the way. From many quarters of the city you can glimpse "the glory that was Greece" in the form of the Acropolis looming above the horizon, but only by actually climbing that rocky precipice can you feel the impact of the ancient settlement. The Acropolis and Filopappou, two craggy hills sitting side by side; the ancient Agora (marketplace); and Kerameikos, the first cemetery, form the core of ancient and Roman Athens. Along the Unification of Archaeological Sites promenade, you can follow stone-paved, tree-lined walkways from site to site, undisturbed by traffic. Cars have also been banned or reduced in other streets in the historical center. In the National Archaeological Museum, vast numbers of artifacts illustrate the many millennia of Greek civilization; smaller museums such as the Goulandris Museum of Cycladic Art Museum and the Byzantine and Christian Museum illuminate the history of particular regions or periods. Athens may seem like one huge city, but it is really a conglomeration of neighborhoods with distinctive characters. The Eastern influences that prevailed during the 400-year rule of the Ottoman Empire are still evident in Monastiraki, the bazaar area near the foot of the Acropolis. On the northern slope of the Acropolis, stroll through Plaka (if possible by moonlight), an area of tranquil streets lined with renovated mansions, to get the flavor of the 19th-century's gracious lifestyle. The narrow lanes of Anafiotika, a section of Plaka, thread past tiny churches and small, color-washed houses with wooden upper stories, recalling a Cycladic island village. In this maze of winding streets, vestiges of the older city are everywhere: crumbling stairways lined with festive tavernas; dank cellars filled with wine vats; occasionally a court or diminutive garden, enclosed within high walls and filled with magnolia trees and the flaming trumpet-shaped flowers of hibiscus bushes. Formerly run-down old quarters, such as Thission, Gazi and Psirri, popular nightlife areas filled with bars and mezedopoleia (similar to tapas bars), are now in the process of gentrification, although they still retain much of their original charm, as does the colorful produce and meat market on Athinas. The area around Syntagma Square, the tourist hub, and Omonia Square, the commercial heart of the city about 1 km (½ mi) northwest, is distinctly European, having been designed by the court architects of King Otho, a Bavarian, in the 19th century. The chic shops and bistros of ritzy Kolonaki nestle at the foot of Mt. Lycabettus, Athens's highest hill (909 feet). Each of Athens's outlying suburbs has a distinctive character: in the north is wealthy, tree-lined Kifissia, once a summer resort for aristocratic Athenians, and in the south and southeast lie Glyfada, Voula, and Vouliagmeni, with their sandy beaches, seaside bars, and lively summer nightlife. Just beyond the city's southern fringes is Piraeus, a bustling port city of waterside fish tavernas and Saronic Gulf views.
