The old town of Nesebar has been declared a World Heritage Site by UNESCO. It's on the coast of the Bulgarian Black Sea. It's well worth a visit, but in summer, it gets very crowded because many people come daily to the beaches and to discover the new city of Nesebar, as well as other places nearby. Nesebar has a rich historical and architectural legacy, and like many other places in the Balkan region, it reminds us of a crossroads between old empires. Besides the old monuments of its rich historical past, it has a nice beach and a picturesque seaport.
