Gonio[1][2] (Georgian: გონიო) is a settlement south of Batumi, in the Gonio-Kvariati district of the city.

[3] According to the archaeological data, the oldest settlement in Gonio dates back 8-7 BC.

Plinius II was the first to mention Apsirtus in the first century AD and this is the oldest reference about fortress.

However, this is unverifiable version as the Georgian government currently prohibits digging near the supposed gravesite.

Other archaeological excavations are however taking place on the grounds of the fortress, focusing on Roman layers.
