The Old Town occupies the narrow rocky peninsula that gives Sozopol its character. Roughly six blocks long and three wide, it is a maze of cobbled lanes, fishermen's chapels, and traditional Black Sea houses with stone ground floors and overhanging timber upper storeys. There are no major monuments — just the texture of the place, best appreciated on foot at sunset when the sea is to the west on one side of the peninsula and the harbour to the east on the other.
Walk out to the southern tip of the peninsula, where the lanes end at low cliffs above the sea and a small lighthouse marks the entrance to the bay. The stones are slippery; wear something other than flip-flops.
