Trieste is the capital city of the Friuli Venezia Giulia region in northeast Italy. A port city, it occupies a thin strip of land between the Adriatic coast and Slovenia’s border on the limestone-dominated Karst Plateau. Italian, Austro-Hungarian and Slovenian influences are all evident in its layout, which encompasses a medieval old city and a neoclassical Austrian quarter.

In Croatia, the Old Town of Split wraps around the luxurious palace where the Roman emperor Diocletian lived out his last days after abdicating in AD 305. Today, this remarkable white limestone palace, a UNESCO Site, awaits your discovery. Part luxurious villa, part military camp, the palace is enclosed by imposing walls and connected by roads linking the eastern Silver Gate with the Iron Gate to the west. Within: an octagonal domed mausoleum, temples and a monumental court accessing the imperial apartments.

Forts and fishing villages, beaches and bazaars, sailing harbors and seashores- When Marco Polo set out to explore the East in 1271, these are the treasures he left behind in his hometown. Some elements have changed little in red-roofed, sun-drenched Kor ula.

Kotor is located along one of Montenegro’s most beautiful bays. First settled during the days of ancient Rome, the city today has a well preserved urban centre with a vibrant community. Medieval architecture and numerous monuments of cultural heritage have made Kotor a UNESCO listed “World Natural and Historical Heritage Site.”

Fortresses flank your entrance to this most beautiful of the Ionians. Lose yourself in the Venetian old town or head north for dramatic seascapes. Sample shore excursion: Achillion Palace & Private Villa.

Taormina is a hilltop town on the east coast of Sicily. It sits near Mount Etna, an active volcano with trails leading to the summit. The town is known for the Teatro Antico di Taormina, an ancient Greco-­Roman theater still used today. Near the theater, cliffs drop to the sea forming coves with sandy beaches.

Rising behind the wide curve of its bay with brooding Mount Vesuvius and the deep blue sea as a backdrop, Naples, Italy enjoys a magnificent natural setting. It is the third-largest city in Italy after Rome and Milan, and arguably the most colorful and seductive of them all: Splendor and squalor live side by side in 21st-century Naples, and the mix is intoxicating.

Cruise to Naples, home to world-class museums and attractions. Naples has something for everyone – superb restaurants, eclectic shopping, a thriving contemporary art scene and an edgy and vibrant street life. But once you’ve had enough of the pounding traffic and jostling crowds while sightseeing in Naples, there are endless opportunities for exploration further afield. The celebrated Roman ruins of Pompeii and Herculaneum, both victims of Vesuvius’ devastating 79 C.E. eruption, lie just south of the city. Explore Naples’ history or take a short ride over to the island of Capri on a Naples shore excursion. The delightful town of Sorrento and the magnificent scenery of the Amalfi Coast are also within easy reach, and the dolce vita glamour of Capri—not to mention the healing thermal waters of Ischia—are a short hydrofoil hop from the mainland. Naples cruises offer a perfect mix of cultural and natural attractions.

When you embark on a cruise to Rome with Holland America Line you experience its bustling modernism along with its rich history. You can walk in the footsteps of emperors, have coffee in Renaissance piazzas and see contemporary art all in one afternoon. Your sightseeing time in Rome begins at the nearby port of Civitavecchia, a seaside town with roots that stretch back to the Etruscan era. Take note of the Forte Michelangelo (both Bramante and Michelangelo had a hand in its design), and the lungomare, a lively stretch along the sea with beach clubs, bars and restaurants.

Once in the Eternal City you can fill your day with museums, churches, archaeological sites, traditional trattorias, artisan shops and, of course, gelato. The Colosseum and the Vatican Museums are Rome’s superstar attractions, but there are plenty of quieter gems to explore. For food lovers there are the markets in Campo de’ Fiori or the slightly farther flung Testaccio. The hip neighborhood of Monti, next to the Colosseum, has a vibrant piazza scene and boutique shopping, while the Villa Borghese offers a green oasis with a view towards Saint Peter’s Basilica and the masterpiece-filled Galleria Borghese. Although Rome might not have been built in one day, you’ll certainly be able to see its highlights on our Rome cruises along with the top things to do there in 24 hours.

Access to the best of Tuscany: Florence, with its magnificent art and architecture and elegant shopping; Pisa’s Leaning Tower; and ancient Lucca. Sample shore excursions: Tuscan Countryside & Wine Tasting; Florence & the Academia.

Marseille, in the south of France, has more spice, grit and edge than the Provençal towns that surround it. A trade city since the time of ancient Greece, the port always seems to be on the brink of change, generating a certain energy that’s hard to find in the timeless and traditional countryside. In fact, sometimes it doesn’t seem very French at all.

Thanks to a multicultural population, the culinary scene (with seafood dishes and Michelin-starred restaurants galore) goes beyond the classic steak frites at bistros and brasseries. A 19th-century cathedral presides over the city and the working-class Le Panier district has winding streets flanked by fading facades, while Baroque edifices grace the commercial thoroughfare La Canebière, once compared to the Champs-Élysées.

Marseille’s 2013 turn as the European Capital of Culture sprouted a crop of cultural venues, from striking museums to cutting-edge gallery spaces and thought-provoking concept shops that showcase local talent. The waterfront has been refurbished—and on sunny days, it’s the place for people- and boat-watching from restaurants famous for bouillabaisse or outdoor cafés serving glasses of rosé and pastis.

On the northeast coast of Spain, overlooking the Mediterranean, Barcelona is a vibrant port city, packed with centuries of iconic art and architecture—Gaudí and Picasso both called it home—and lined with sunny white-sand beaches. Explore the Catalan capital’s tourist attractions and historic neighborhoods, Modernisme and world-renowned art museums, galleries and local crafts shops—some of which are centuries old and stock traditional Catalan wares. After you see the sights, there are lively tapas bars around every corner where you can stop for a drink, a café amb llet (Catalan for espresso with steamed milk) or a snack, no matter the hour. Green spaces for picnics, long walks and respite from the hustle and bustle are scattered throughout Barcelona’s attractions: There’s Gaudí’s mosaic-decorated park, a neoclassical maze at the Laberint d’Horta, as well as plenty of high places (mountains, monuments and edifices) where sightseeing visitors can take in the view. A short trip from Barcelona by car or train, luxury outlets, cava wineries, a mountaintop abbey and the sandy beaches of the Mediterranean coast await.

“And suddenly there is Cagliari: a naked town rising steep, steep, golden-looking, piled naked to the sky,” wrote D.H. Lawrence in 1921 when he traveled to Sardinia. Nearly 100 years later, the city that made the writer “think of Jerusalem” is just as impressive, sitting between a blue sea and an azure sky. According to Greek mythology, “Caralis” was founded by Aristeus, son of Apollo, though historians date it to the 8th century B.C.E., when the Phoenicians established a trading port here. Sardinia’s capital was later fought over by Carthaginians, Romans, Pisans, Spanish and Piedmontese—all of whom shaped its development.

Most sights are in Castello, the old town that climbs the hill behind Saint Remy’s rampart. It’s a rough grid of narrow streets and small squares with breathtaking views of sea, city and mountains. And while the old stones of Castello reflect millennia of history, Cagliari also has natural riches, with white beaches and flamingo-dotted blue lagoons nearby.

Sardinia has one UNESCO-listed site: a megalithic nuraghe complex 60 kilometers north of Cagliari (though some would argue that the town’s Roman amphitheater and Tuvixeddu necropolis could also be candidates for UNESCO recognition). Whether you are a history buff or drawn more to culinary or natural wonders, you’ll find much to delight in this lively, fascinating city.

Stroll Tunis’ spirited medina where close-packed souks offer silver, perfumes, spices, carpets and other treasures at fire sale prices. Sharpen your haggling skills here—it’s anticipated! At the edge of the Sahara, the Phoenician city at Carthage now lies in windswept ruins, but once was the glorious rival of Rome.

Thick sandstone walls fortify Valletta, holding within its stone streets and glorious architecture. It fees like a travesty, walking over the detailed inlaid marble floors of the the cathedrals, but they are there to be seen and appreciated. The Silent City is Mdina, on the far side of the island, where no cars are permitted to disrupt the serene streets. Keep an eye out for the legendary, aged yellow buses of Malta which appear to be on their last legs, but are in fact a revered and flawlessly maintained piece of Maltese heritage.

No modern metropolis is more steeped in myth than Athens, Greece. From the gritty port of Piraeus—gateway to Greece’s fabled isles—to the Parthenon—eternal symbol of Western civilization—Athens has attracted adventurers and classicists for centuries. This heritage is still very much alive for modern visitors sightseeing in Athens: ancient stadiums and temples dwell alongside apartment blocks, modern performances are staged in the marble amphitheaters where Greek drama was born and millennia-old monuments are scattered in the archaeological park that circles the Acropolis.

One of the world’s oldest maritime powers, Athens is blessed with a balmy climate and stunning coastline. The seaside suburbs of Athens are scalloped with sandy beaches, fancy yacht clubs and glamorous beach bars. While the Athenian lifestyle is known for late-night dinners and dancing until dawn, the city shines brightly by day in the bustling markets, lively cafés and fascinating museums that illuminate Greece’s past and present. Contemplate the magnitude of all that culture and ancient tourist attractions while marveling at the sun setting into the Aegean or rising over the Acropolis.

In the quiet of the original Olympic stadium, where the torch was first lit and the winners were crowned with a laurel wreath, let your imagination run. Step into the ruined archives of Greek mythology at the Temple of Zeus—one of the few remaining Wonders of the Ancient World.

Taormina is a hilltop town on the east coast of Sicily. It sits near Mount Etna, an active volcano with trails leading to the summit. The town is known for the Teatro Antico di Taormina, an ancient Greco-­Roman theater still used today. Near the theater, cliffs drop to the sea forming coves with sandy beaches.

Messina’s astrological clock is as much a man-made masterpiece as the road leading to Taormina, which canitlevers out of the rocky cliff face and stands on impossibly tall pylons. Leave it to the Italians to design a road that’s both a thrill-ride and a feat of engineering! Once you’re safely in Taormina, walk to the sublime Greco-Roman theatre that overlooks Naxos Bay and snow-capped Mt Etna, and spend some time on the Corso Umberto with a gelato firmly in hand.
