Gonio Fortress

Gonio Fortress: Where Roman Legions Met the Myths of Colchis

Just a short drive from the bustling seaside energy of Batumi lies a place where time feels layered and tangible. Gonio-Apsaros Fortress is not just another ruin; it’s one of Georgia’s most complete and evocative historical sites, a perfectly preserved Roman outpost on the very edge of the ancient world. To step inside its massive stone walls is to walk through centuries of history, from the legends of the Golden Fleece to the marching sandals of Roman legionaries.

The story of Gonio is ancient, woven into the very fabric of Greek mythology. It is said that this was the spot where King Aeëtes buried his son, Apsyrtus, who was dismembered by his sister Medea as she fled with Jason and the Argonauts. Long before the Romans arrived, this place was already steeped in legend. But it was under Roman rule, beginning in the 1st century AD, that Apsaros became a formidable military and strategic center. It was a critical stronghold, guarding the mouth of the Chorokhi River and the trade routes that led deep into the hinterland.

What makes Gonio so breathtaking today is its state of preservation. The rectangular layout, the high walls, and the eighteen towers are almost entirely intact. Walking the perimeter, you can easily imagine the daily life of the Roman garrison stationed here. You can see the remains of the barracks, the bathhouses, and the water systems that supported a small city within these walls. It was a vital piece of the Roman Empire, a beacon of order on a wild and distant frontier.

The fortress’s story didn’t end with Rome. It was later held by the Byzantines and then the Ottomans, each leaving their mark on its structure and its history. But perhaps its most profound later significance is as the reputed burial place of the Apostle Matthias, who was chosen to replace Judas Iscariot among the Twelve Apostles. While the grave’s location is disputed, the tradition adds a deep layer of spiritual importance to the site.

Today, Gonio Fortress is also home to an excellent archaeological museum. The artifacts unearthed within its walls—pottery, coins, tools, and jewelry—bring the stories of its former inhabitants to life. They are a direct link to the soldiers, traders, and officials who lived and worked here over two millennia.

Visiting Gonio is less like a hike to a remote ruin and more like exploring a living museum. It’s accessible, informative, and utterly captivating. You don’t need to be a history scholar to feel the power of this place. You just need to stand in the center of the great courtyard, look up at the towering walls, and listen to the whispers of empires and myths carried on the Black Sea breeze.
