Nesebar is an ancient city and one of the major seaside resorts on the Bulgarian Black Sea Coast, located in Burgas Province. It is the administrative centre of the homonymous Nesebar Municipality. Often referred to as the "Pearl of the Black Sea", Nesebar is a rich city-museum defined by more than three millennia of ever-changing history. The small city exists in two parts separated by a narrow man-made isthmus with the ancient part of the settlement on the peninsula, and the more modern section on the mainland side. The older part bears evidence of occupation by a variety of different civilisations over the course of its existence.
It is one of the most prominent tourist destinations and seaports on the Black Sea, in what has become a popular area with several large resorts—the largest, Sunny Beach, is situated immediately to the north of Nesebar.
