City-states are rare in the present day—and none are quite like Singapore. In the 20th century, the Southeast Asian nation hurtled itself into the modern world, and it continues to expand its state-of-the-art transportation system and build its edgy skyline. Yet Singapore’s urban plan wisely maintained its intimate neighborhoods, many with streets lined with colorful shophouses (a type of building unique to parts of Asia, with businesses located on their ground floors and residences above). Add the city’s mix of ethnic groups—mainly Malays, Chinese and Indians—and you get a vibrant cultural scene that attracts a cosmopolitan, international community.

Singapore’s food scene—which is arguably the world’s most dynamic and runs the gamut from beloved street hawkers to Michelin-starred venues—would merit a trip alone, as would its never-ending shopping options. But the city is also packed with world-class museums, many designed by celebrated architects, and it hosts many major international events, such as the Formula One Grand Prix. Yet only about half of the 720-square-kilometer (278-square-mile) island is developed, which leaves plenty of room for parks and open spaces such as the Bukit Timah Nature Reserve, where an old-growth forest still thrives.

Scarred by decades of civil war, Sri Lanka and its commercial capital, Colombo, are relatively new to modern-day tourism. But Colombo has been a crucial trading post for more than 2,000 years. The city rose to prominence as Sri Lanka’s most important port town in the 16th century with the arrival of Portuguese fleets. After a period under Dutch rule, Ceylon—as Sri Lanka was then called—became part of the British Empire in 1802. Sri Lanka gained independence in 1948, but the country experienced intense unrest from 1983 until 2009, when Sri Lanka’s civil war finally came to an end.

Many visitors head for the pristine beaches or up to the mist-draped mountains of Sri Lanka’s tea country, and find that Colombo merits more than just a quick stop. Development continues at breakneck speed here, with skyscrapers jostling for space alongside the elegant architecture of its colonial past. Bustling markets and newfangled shops rub shoulders with ancient temples and rich layers of history in this fascinating place.

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.

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.

Even just a day here will open your eyes to the natural beauty and subtle charms that make proud and elegant Alicante a gem of the Costa Blanca.

Find your way in the city that launched the Age of Discovery. Cross the River Tagus on its soaring suspension bridge, watched over by a colossal statue of Christ. Wander the maze of streets in the Alfama, the old Moorish quarter, dominated by the medieval Castle of St George where peacocks strut and shriek. Stroll the Baixa and refuse to leave without a pair of elegant shoes.
