Nessebar is an ancient town and one of the major seaside resorts on the Bulgarian Black Sea Coast, located in Burgas Province. It is the administrative centre of the Nessebar Municipality Often referred to as the "Pearl of the Black Sea", Nessebar is a rich city-museum defined by more than three millennia of ever-changing history.
It is a 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 Nessebar.
Nesebar has on several occasions found itself on the frontier of a threatened empire, and as such it is a town with a rich history. The ancient part of the town is situated on a peninsula (previously an island) connected to the mainland by a narrow man-made isthmus and it bears evidence of occupation by a variety of different civilisations over the course of its existence. Its abundance of historic buildings prompted UNESCO to include Nessebar in its list of World Heritage sites in 1983.
