7 Nights Europe, Mediterranean

Greece's capital and its largest city was born atop the Acropolis, where ancient warrior-kings once dwelled. These ruins are a testament to the golden age of Greece, and the Parthenon is considered the most architecturally sophisticated temples of its time. Ancient Agora, a sprawling array of stones, slabs and foundations, was once the focal point of ancient Greek life.

Corfu was once ruled by Venetian doges, Turkish sultans and French invaders. Marvel at the 17th-century icons in St. George's Church, the medieval Palace of Phrourio and the 19th-century Achilleion Palace. The greenest of the Greek Isles, Corfu also boasts thriving vineyards and olive orchards among its rugged mountains.

This Sicilian port city is noted for the Duomo, an elegant reconstruction of the medieval cathedral built by Roger II, and the detached campanile, which contains the largest astronomical clock in the world. Ruins salvaged from past natural disasters are housed in the Museo Regionale.

The capital of Catalonia boasts the bustle of the world's busiest seaport, the medieval romance of its Gothic Quarter, and a feast of Catalan Art Nouveau buildings - including the great creations of Antonio Gaudí. The "Great Enchantress" remains one of the most exhilarating cities in Europe, decorated with the grandeur of Picasso, Miró and Dalí.
