Most people visit the central Italian city of Ravenna for its superb Byzantine mosaics - and rightly so, for they are the finest outside Istanbul. A thriving seaport in ancient times (it now lies five miles inland), Ravenna rose to power in the 1st century BC under the Emperor Augustus. The Roman emperor built a port and naval base at nearby Classe, which is currently undergoing archaeological excavation. The town converted to Christianity very early, in the 2nd century AD. As Rome's power declined, Ravenna took over as capital of the Western Empire (402 AD). The following century it came under the rule of Thedoric and the Arian Ostrogoths, and in 540 the city became part of the Byzantine empire under Justinian. Ravenna's exquisite early Christian mosaics span the years of Roman, Ostrogothic and Byzantine rule. Today, Ravenna is a very pleasant town of about 140,000. It looks much like any other Italian city at first glance, with old streets, fine shops and peaceful squares, but the Byzantine domes of its churches still evoke its Eastern heritage. Ravenna's early Christian churches and mosaics have been collectively designated a World Heritage Site. As an extra bonus, Ravenna is a great place to taste the famously delicious food of the Emilia-Romagna region.
