Why go
Gonio-Apsaros is one of the best-preserved Roman fortresses in the former empire, a 4.5-hectare citadel where stone walls still rise 5 meters high above the Chorokhi River delta. Founded as Apsaros in the 1st century AD—possibly where the Argonauts buried their steersman—this strategic outpost guarded Rome's eastern frontier and later housed a Byzantine garrison. The visible remains include 18 towers, a double-walled circuit, and the excavated ruins of Roman hypocaust baths with their brick heating channels intact. Its worth lies in rare physical immediacy: you walk the same ramparts where legionaries stood, the Black Sea surf audible beyond the walls, archaeology still ongoing.
