You could spend a lifetime in Europe’s oldest city and still not see everything it has to offer. Settled over 3,500 years ago, Athens is like a mythological crossroads of the past and present, where modern buildings share the skyline with spectacular ruins like the Parthenon.

To see a veritable “greatest hits” line-up, make your way to Vasilissis Amalias Street for the archaeological walk. Winding through the heart of the ancient city, the route leads to landmarks like the Temple of Olympian Zeus, Ancient Agora, Arch of Hadrian, and of course, the Acropolis.

Your daydream of a Greek island meets reality in Santorini – its whitewashed villages cling to cliff sides, and bright blue roofs reflect the sea and sky. So beautiful is it, that you can almost believe the myths that claim it as the birthplace of gods. Born itself as a volcanic cone, the island blew its top in 1450 BC, its center sank, and it assumed its current crescent shape, outlined by three main islands. The capital, Fira, a pedestrian haven with narrow, meandering cobblestone lanes, is reachable only by cable car, donkey, or for the fit and fearless, a flight of 600 steps.

This Greek seaside town is the gateway to the ruins of Olympia, where the ancient games began in 776 BC, and continued for over 1000 years, until they were outlawed as a pagan festival, after Rome officially adopted Christianity as the only legitimate imperial religion. The complex is made up of temples, workshops, and the training structures that have given us the word we still use today to describe such facilities – gymnasium. The games did not recommence until 1896, but their ancient roots are acknowledged when the modern Olympic flame is lit here every four years, before beginning its long journey to the host nation.

One of the most beautiful islands in all of the Mediterranean, Corfu is said to cast a spell upon those who land upon its shores, which is perhaps why Shakespeare set his magical play, The Tempest, here. Millions of silvery olive trees grace the hillsides, the scent of lemon blossoms perfumes the air, and picturesque views of sapphire bays set against verdant hills capture your attention. A leisurely stroll through the narrow alleyways of Corfu old town will reveal many local treasures – old churches, a Byzantine cathedral, small enticing shops, and tavernas offering local wines and fresh seafood.

Kotor’s beautiful bay has long attracted passing ships that stopped to trade, plunder, or conquer, and merchants, pirates, and soldiers of numerous empires have walked this maze of cobblestone streets before you. One of Europe’s best-preserved cities of medieval or Renaissance vintage, its walls were constructed right into the steep slopes of the mountain behind it, providing protection and making it an amazing sight on approach from the sea. Venetian ramparts enclose a rich history, with churches of varying styles, and a Romanesque cathedral built on the foundations of an earlier church, and a still earlier Roman temple.

To visit Dubrovnik is to step back in time to the Middle Ages. The town is one massive museum, its thick walls constructed from the 13th to the 17th century encircle the entire city, and contain within them a treasure trove of striking architecture – squares, fountains, palaces, churches, and monasteries, all built from the same stone, line streets free of motor vehicles. Once the only city-state on the Adriatic to rival Venice, Dubrovnik has long been a center for Croatian culture, and home to artists and scholars of all disciplines. It is possible to circumnavigate the city atop the medieval walls.

Just 55 miles north of Split is the city of Sibenik, situated where the River Krka meets the Adriatic. Since 1066, it has been under rule by Croatians, Venetians, Austro-Hungarians, Yugoslavians, and once again back to Croatians—which has resulted in a diversity of international influences.

This is particularly evident in the old part of Sibenik, with its many churches, palaces, Dalmatian houses, as well in the city’s stone walls and four fortresses: St. John, St. Michael, St. Nicholas and Šubićaevac. A must see is the Cathedral Sveti Jakov, and if you love the great outdoors, then visit Krka National Park or Kornati National Park.

One of the world’s most beautiful cities also happens to be one of its most unusual. Venice is actually made up of over 120 islands in the Adriatic Sea. Because the city is connected by canals instead of streets, a good way to see Venice is on a romantic gondola ride. The epicenter of the city is St. Mark’s Square, where you’ll find the 900-year-old Basilica of St. Mark
