From the World Heritage inscription:
The ‘Pearl of the Adriatic’, situated on the Dalmatian coast, became an important Mediterranean sea power from the 13th century onwards. Although severely damaged by an earthquake in 1667, Dubrovnik managed to preserve its beautiful Gothic, Renaissance and Baroque churches, monasteries, palaces and fountains. Damaged again in the 1990s by armed conflict, it is now the focus of a major restoration programme co-ordinated by UNESCO.
Dubrovnik is an very nice, historic town on the Adriatic. Almost all of the original walls of the city are still in place and the old city managed to escape too much damage during the break up of Yugoslavia. I arrived in Dubrovnik during a stop on a cruise ship which was just enough to explore the old city on my own time. I was able to walk twice around the walls of the city as well as explore many of the side streets of the old town itself. It is listed as one of the top 100 Wonders of the World by Howard Hillman.
