There are buses every half an hour to this Adriatic port city, which is replete with Roman and Byzantine heritage.
The first place to go is the amphitheatre, which is from the 2nd century, was once able to seat 20,000 and is the largest in the Balkan region.
It was hidden to the world for more than a millennium before being rediscovered in 1900. What really adds to the site is the small chapel attached to the building, which has fantastic early-Christian mosaics and frescoes depicting saints.
