Historical Background

Roman Origins (1st Century AD)

The fortress dates back to at least the 1st century AD, with evidence of Roman military architecture and later fortifications added under Byzantine and Ottoman rule. During the Roman period, Gonio was a fortified Roman city known for its theater and hippodrome—indicating its importance beyond just a military outpost. The fortress was first mentioned by the Roman writer Pliny the Elder in the 1st century and later by Appian in the 2nd century.

Strategic Function

The fortress had a unique strategic function: it protected the entrances to the Chorokhi and Acharistskali river valleys, which connected South-West Georgia to the Black Sea coast. Its thick stone walls and commanding towers convey a sense of strength and endurance, controlling trade routes and military approaches along the western Black Sea region for centuries.

Byzantine & Genoese Periods

Later, the area came under Byzantine influence, and the name appears in records from the 14th century. There was also a brief Genoese trading post here, adding another layer of commercial history to the site.

Ottoman Era (1547 – 1878)

Gonio was taken over by the Ottomans in 1547. Despite the Georgians‘ numerous attempts to regain the fortress, it remained fully under Ottoman control until the Russian Empire began its drive to the West. After several skirmishes followed by an all-out Russia-Turkey war, the Russian Empire gained rule over Adjara through the 1878 San-Stefano Treaty. In 1647, Cossacks briefly captured it but soon lost it to Ottoman forces.

Modern Era

The fortress was converted into a museum in 2010, offering visitors a glimpse into centuries of history with exhibits ranging from the early 19th century to the 1980s. Today, ongoing archaeological excavations continue to reveal Roman and early Christian artifacts, highlighting the site‘s long-standing importance as both a military and cultural hub.

Legends & Religious Significance

The Legend of Apsaros (Argonauts)

Gonio-Apsaros history is closely linked to the myth of the Argonauts. According to legend, King Aeetes of Colchis buried his son Apsyrtos (or Apsaros) at this location after he was killed by the escapee Jason. This connection gives the fortress its alternative name: Apsaros or Apsyrtos Fortress.

Tomb of Saint Matthias the Apostle

One of the fortress‘s most significant religious claims is that it may contain the tomb of Saint Matthias, one of Christ‘s twelve apostles who took the place of Judas Iscariot. According to tradition, Matthias preached and was buried here.

A memorial stone marking the supposed grave can be visited inside the fortress. However, Georgian authorities have prohibited digging near the supposed burial spot, so the claim cannot be archaeologically confirmed. Regardless, this adds a layer of religious significance that attracts pilgrims and history enthusiasts alike.

“This place is absolutely stunning with loads of history and lush greenery everywhere you look. You can climb the walls from the inside, but be cautious—there's no railing, so it's quite scary and easy to fall.

What to Expect (Honest Assessment)

“Honestly, mixed feelings. The fortress walls are fine. You can look at it as a historical place, but everything inside is more like decorations to show what it might have looked like in Roman times. The excavations feel deceitful, and there‘s really nothing else to see.” – Visitor review

“All that remains of the fortress are the surrounding walls. The rest has largely disappeared. Essentially, it‘s an open grassy area enclosed by stones. If you enjoy history and have a vivid imagination, and if your accommodation isn‘t far from the site, it might be worth a visit.” – Visitor review

Pro tip: Manage expectations—this is primarily an archaeological site with impressive walls, not a fully reconstructed castle. History enthusiasts and those with imagination will appreciate it most. For a quick trip combining history with beach time, it‘s ideal.
