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 doesnt 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.

This strategic link between the Atlantic and the Mediterranean has been ruled by the Spanish, British and Moors. As long as the Barbary Apes remain, the British will rule Gibraltar this is the tradition that has held for 350 years. These pesky primates are a favorite with visitors despite their incessant chatter and light-fingered ways. Ride to the top of the Rock for great views over the Strait of Gibraltar-on a clear day you’ll see Africa.

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.
