       VARNA is the third largest city in Bulgaria located on the Black Sea coast. Because of its rich history and dynamic present, it is often called the "Sea Capital of Bulgaria". The city's geographical location, rich natural resources and ancient history determine its image of one of the most famous and beautiful resort centers in Europe and the largest in the Black Sea region.
