Ravenna

Located on the Adriatic coast, Ravenna was briefly the capital of the Roman Empire in the 4th century after which it fell under Byzantine control for over 200 years. However, the city rapidly declined once the river on which the city depended silted up and trade ceased. Neglected until the late 19th century when a canal was constructed, the city has the most intact Byzantine buildings in the world.

Within these buildings are the most extraordinary mosaics. Not only are these mosaics undamaged but they are incredibly vibrant and colourful.

This is also the final resting place of Dante after his bones were dragged around for several hundred years....
 
Of course, very few tourists come here, which makes Ravenna even more appealing.
