Greek Isles & Sicily 7 Nights • Barcelona, Spain to Athens (Piraeus), Greece • Celebrity Xcel

Formerly a sleepy Spanish city, Barcelona has recently been reborn as an eclectic fusion of the modern and medieval. This coastal city exudes European charm and welcomes multitudes of travelers every year. It’s a major destination with must-see architectural gems that date back some 2,000 years. You’ll encounter fascinating examples from the Roman Empire, the Middle Ages, the Modern masters like Gaudî, and many Cataluñian greats. Outstanding art museums can be found throughout the city, proudly displaying the works of world-renowned artists and countrymen, including Goya, Pablo Picasso, Salvador Dalî, and Joan Miró. For a respite from the hustle and bustle of the city center, venture to the awaiting Mediterranean Sea and all the seaside has to offer. Maybe a brisk hike in the nearby forest covered Collserola Hills or the hilltop in Montjuïc with its botanical gardens is the perfect recharge for a rollicking evening in one of the premier party capitals of the world. Round out your cruise to Barcelona dining at a tapas bar and savor a variety of delicious small dishes to share—from traditional Spanish to the more innovative.

Long considered a strategic prize, the Sicilian city of Palermo has changed hands dozens of times throughout its tumultuous history. Spend time here on your Europe cruise and you’ll find remnants of Viking, Arab, Roman, and Phoenician cultures to name just a few. Visit the Temple Valley of Agrigenro, a UNESCO Heritage Site. Take a panoramic city tour to see the highlights, then visit the impressive Catacombs of the Capuchin Friars, where more than 8,000 mummified bodies of monks, noblemen, and citizens are dressed in their original 15th century clothes. The most touching sight is the body of Rosalia Lombardo, almost perfectly preserved though this baby girl died in 1920, at the tender age of two.

Rhodes, the friendliest city in the Mediterranean, is situated at the island’s northernmost point. This sunny retreat is also home to many historic sites, such as the ruins of the Temple of Venus and the medieval Street of Knights. Rhodes, pronounced ro-dos, is the largest of the Dodecanese Islands. The varied landscape with beaches, wooded areas, and ancient ruins also make this one of the most alluring of the Greek archipelago. A cruise to Rhodes wouldn’t be complete without exploring the picturesque Old Town with its winding streets and Byzantine legacy. Enter the gateways of Rhodes and step back to a time when the Knights of St. John of Jerusalem built a Christendom stronghold. Or, tour the restored Palace of the Grand Masters and the Hospital of the Knights. You can spend the day amid the chronicles of Greek history. Immerse yourself in the whitewashed romance of the archaeological site, Lindos and climb to the ruins of its ancient Acropolis for sweeping views of the village and the blue seas beyond. The island’s vibrant shops, great restaurants, and glittering clubs buzz with a happy, modern energy in contrast to the grace of its ancient history.

Santorini, Greece

Here on the island of Santorini, you’ll find a classic Greek seascape—whitewashed houses accented by sea-blue roofs. This is a treasure trove for both professional and amateur archeology buffs, with sites that include tombs that date back to the 9th century and the sanctuary of Apollo. In many ways, Santorini could be considered an explosive place, being that its terraced collection of homes and windmills lie on a caldera-- a huge basin formed by an erupting volcano. The island’s volcanic past has also produced delicious grapes for excellent wines that are well worth investigating while on your Santorini cruise. Some of the best on the island can be found in Pyrgos, Megalochori, and Oia. Oia’s hilltop not only has the ancient, Minoan site of Akrotiri, but is quite possibly the best vantage point from which to witness the spectacular sunsets. And, if you have some time, take a short trip to the island of Nea Kameni for a dip in its famous hot springs. The warm dark waters are enriched with iron and manganese and considered therapeutic.

Mykonos is known for its whitewashed villages sprinkled with blue and jade green. It's also famous for its sophisticated nightlife. The most popular island in the Cyclades is bustling with activity, awash in beautiful alleyways, and home to alluring sandy beaches.

Athens brought the world drama, history, poetry, and philosophy. Once home to the world's most powerful and civilized empires, Athens is now the world's foremost archaeological playground. The towering columns of the Parthenon still stand in homage to the virgin goddess Athena. The Parthenon sits atop the Athenian Acropolis and watches over the city where it can be seen from just about anywhere in Athens. Make it a point to visit the incredible Acropolis Museum on your cruise to Athens. The joint effort between two architects, one American and the other Greek, this outstanding building was completed and opened to the public in 2009. It focuses primarily on the Greek period dating to 5 B.C., considered to be the apex of art, culture, and philosophy in ancient Greece, but it also has artifacts from the Bronze, Roman, and Byzantine Ages. There’s even a Plexiglas walkway from which an excavated section of an old Athenian neighborhood can be viewed. In addition to an abundance of historical riches, modern Athens has plenty on offer—from scenic beaches to restaurants with superb Mediterranean cuisine and bustling central markets.
