Barcelona is a walkable global city known for breathtaking architecture, world-class museums, bustling markets, parks, and fashion.

Palma, capital of the Balearic Islands, is known for La Seu, the Cathedral of Santa Maria over the bay, the nearby Almudaina Palace, and Bellver Castle, which houses the city museum.

Mallorca also offers beaches, shopping on Jaime III and Passeig del Born, and sights like the monastery where George Sand and Chopin stayed and Cuevas del Drach.

Saint-Tropez is famed for designer shopping, all-night nightlife, and luxe beach clubs like Le Club 55 and Nikki Beach. Made famous by Brigitte Bardot, who still lives here, it also has a quieter side in the hills: narrow cobblestone streets and a 17th-century citadel with stunning port views.

Cannes, on the French Riviera, is world-famous for its annual film festival and draws the rich and famous to its beaches and stylish scene. The Promenade de la Croisette, lined with designer boutiques, grand hotels, and restaurants, is the place to see and be seen.

Monte Carlo is a glamorous port built for luxury yachts, with some of the world's finest vessels in its harbor.

Tuscany's countryside is dotted with medieval hill towns, cypress-lined roads, and rolling vineyards. Though Chianti, Brunello, and Vino Nobile are famous worldwide, the region's real draw is its art and architecture. Near Livorno, Florence-the cradle of the Renaissance-offers masterpieces by Dante, Galileo, da Vinci, Raphael, Botticelli, and Donatello. Other beautiful towns include Pisa, Siena, Lucca, and San Gimignano.

Rome is a vivid blend of sound, movement, history, and art. Church bells and traffic echo off ancient stone as workers, tourists, and café crowds move through the city.

Its sculptures, Michelangelo's Sistine Chapel, and Bernini's fountains make its art and architecture unsurpassed. Rome belongs not only to Italy, but to the world.
