Along the northeast coast of Italy is where you'll discover the historic town of Ravenna. Once a thriving seaport in ancient times (it now lies five miles inland), Ravenna was also the westernmost pillar of the Byzantine Empire. Just as everyone who visits, you too will marvel at the exquisite Byzantine mosaics. At first glance the old streets, peaceful squares and fine shops resemble any other Italian city, but the Byzantine domes of its churches still evoke its Eastern heritage. As an added bonus, Ravenna is a great place to taste the famously delicious food of the Emilia-Romagna region.

Despite the magnificent 13th century walls that surround the city, Dubrovnik is one of the most welcoming cruise destinations in all of Europe. Dubbed “the pearl of the Adriatic” by the poet, Lord Byron, this Croatian city exudes romantic charm and beautiful scenery with its shimmering marble streets, centuries-old buildings capped by bright orange roofs, and lovely beaches ensconced between awesome rocky ledges.

A beautiful coastal town, a seaport and large industrial area, Bar, Montenegro is also a popular transport hub welcoming trains from Belgrade and ferries from Italy. For this reason, it's the perfect base city for touring the incredible ruins of Stari Bar (Old Bar) in the mountains. A quick history lesson: The northern part of the coast remained under Venice's rule and then Austria, while the southern part spent 300 years under Turkish control. Founded in 1908, "New" Bar has a more modern look and feel, but once you start heading to the Albanian border, you will see more mosques and Ottoman-style buildings.

The history of Salerno is as rich and vibrant as its surrounding landscapes. The site of ancient settlements (Neolithic mummy remains discovered here), Salerno has been home to vast empires and was the site of Medieval Europe's first medical school. A trip to Salerno makes it easy to understand why countless people have been drawn to its location along the Gulf of Salerno. Nestled between the mountains and the sea at the southeastern point of the famed Amalfi Coast, Salerno boasts sun-drenched beaches, nature reserves and parks, historic sites and delicious local cuisine.

Endless adventures await in Rome. With two and a half thousand years of history, art and culture, it is no wonder Rome is one of the most visited cities on the planet.

On the one hand, this city, founded by the Romans some 2,100 years ago, is replete with (literally) wall-to-wall history and architectural splendor. You can journey back in time and wander the mazes of alleyways and cobblestone paths that surround the Gothic cathedral.

The capital of Catalonia, and one of its provinces, Barcelona, is a place of palpable history, where you can lose yourself strolling down the medieval streets of the Barri Gotic. It's a city designed to delight the senses: visit other-worldly Modernista churches like Gaudi's La Sagrada Familia, or treat yourself at a street side cafe to Patatas Bravas or a Passion Fruit Mojito.
