The lay of the land is flat and the seacoast of Kavarna is 42 km long. Along it there are small beaches, including an artificial one.
Cape Chirakman with its almost sheer slopes towers above the seacoast. Remains of stronghold walls, moats, buildings, churches and necropolises can be found on the flat plateau.
The town was founded in the 5th century BC by Ancient Greek colonists who settled on the Chirakman Plateau in the colony Byzone (or Bizone). During the 3rd and 2nd century BC, the town played an important mediating role between the local Thracian settlements and the Greeks. Despite being unsuitable for wharfing because of its rugged cliffs, this part of the Bulgarian Black Sea Coast was an attractive centre due to the fact that the local people produced and traded with high quality grain.
During the second part of the 1st century BC the ancient town fell in the sea because of a disastrous earthquake. The frontal part of the Chirakman broke off and together with the richest citizens fell into the Black Sea’s waters.
