Nesebar previously known as Mesembria and before that as Menebria, is an ancient city on the Black Sea coast of Bulgaria, located in Nesebar municipality, Burgas Province

In modern times, Nesebar is a major tourist attraction in what has become a popular area with several large resorts—the largest, Sunny Beach, is situated immediately to the north of Nesebar.
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 Nesebar in its list of World Heritage Sites in 1983.
