Nessebar, a city-museum and UNESCO World Heritage Site, is another marvellous day trip from Burgas, located just 35 kilometres away. This ancient town, often called the "Pearl of the Black Sea", sits on a small peninsula connected to the mainland by a narrow causeway, offering stunning sea views on both sides. Its cobblestone streets wind through a historic centre filled with over a millennium of architectural treasures, including the Church of St. Sofia, a 5th-century basilica, and other medieval churches like St. John the Baptist and St. Stephen. The Old Town, a maze of narrow lanes and 18th-century houses, invites leisurely exploration, with artisan shops and street vendors adding to its charm. Nessebar was once a Thracian settlement and later a Greek colony, playing a key role in the development of trade and culture in the Black Sea region. Its unique blend of ancient ruins, Byzantine churches, and a lively atmosphere makes it a captivating destination for history enthusiasts and casual vacationers.

Sentiero Rilke is one of the most enchanting paths in Carso, a wonderful walk starting from Sistiana and leading to the castle of Duino along white cliffs. Named after Rainer Maria Rilke, the famous poet from Prague, who loved walking here.

The Roman Theatre was built between the first and second century AD, on behalf of Quinto Petronio Modesto from Trieste and it can hold about 6,000 spectators. The statues that adorned the theatre are now preserved in the Town Museum.
