Norwegian Gem: 7-Night Europe - Greek Isles

Ravenna is a mid-sized city of about 160,000 people in Italy's Emilia-Romagna region, sitting on the Adriatic coast south of Venice. The city served as the capital of the Western Roman Empire, the Ostrogothic Kingdom, and the Byzantine Exarchate, leaving it with the finest collection of early Christian and Byzantine mosaics anywhere outside Istanbul.

Dubrovnik cruise port is the southern gateway to Croatia's Adriatic coast and one of the most visually striking stops in the Mediterranean. Ships dock at Port Gruž, about 3 kilometers northwest of the Old Town, with the walled medieval city perched on a rocky peninsula jutting into the sea.

Kusadasi cruise port is Turkey's busiest and the primary gateway to Ephesus, one of the most significant ancient Greek and Roman cities in the world. The port sits on Turkey's central Aegean coast, about 95 kilometers south of Izmir, with ships docking at the Ege Ports cruise terminal right in the middle of town.

Istanbul cruise port is one of the most extraordinary arrivals in the world. Ships sail up the Bosphorus Strait between Europe and Asia, past Ottoman palaces and Byzantine ruins, and dock at Galataport, the underground cruise terminal in the Karaköy neighborhood right in the center of the city.

Mykonos cruise port is one of the most instantly recognizable stops in the Greek islands. Whitewashed cube buildings cascade down hills to the Aegean Sea, blue-domed churches punctuate the skyline, and windmills stand sentinel on the ridge above Mykonos Town (Chora).
