Nicknamed the “Pearl of the Black Sea,” Nessebar’s Old Town is a UNESCO World Heritage Site, representing centuries of empires stretching back to ancient times. The historic section of Nessebar sits on a peninsula (previously an island) — connected by a manmade isthmus to the mainland where the more modern developments are located. From museums and ancient ruins to buzzing cafes and miles of sun-soaked beaches, there’s something for everyone to enjoy along what has been referred to as the “Bulgarian Riviera.”
