Colussa, Ancient polis in Sinop Province, Turkey
Colussa is an ancient port settlement in Sinop Province on the Black Sea coast and shows remains of buildings and fortifications from several periods. The site spreads across a larger area along the shore with visible foundations, wall sections, and structural remains from different building phases.
Ancient texts mention this place as an important maritime trading settlement during Greek colonization of the Black Sea. The settlement developed over centuries under various influences and was later shaped by local populations.
The ruins show a blend of Greek architecture with local Paphlagonian building methods that developed over several centuries. This mixture is visible in the foundations and wall remains you encounter while exploring.
The site lies on the coastal road between Sinop and Güllüsu and is reachable on foot by following the shoreline. The area has basic facilities and is relatively open to access, so it is wise to bring proper footwear and sun protection.
The location at this point was ideal for watching ships that traveled through the Black Sea region. This strategic feature helps explain why the harbor was occupied and used for such a long time.
