Gonio Fortress (previously called Apsaros or Apsaruntos) is the oldest fortress in Georgia. It is located in the southwestern part of the country in the Gonio village. In the 2nd century it was a well-fortified Roman city within Colchis. The town was also known for its theatre and hippodrome. It later came under Byzantine influence. The name “Gonio” is first attested in the 14th century.

Gonio history is closely connected to the myth of the Argonauts. According to the legend this is the site where king Ayet buried his son Apsaros, whose body was dismembered and thrown into the sea by Jason.

The interested traveler can find out that the oldest archaeological layer excavated here belongs to XVIII-XVII cc. BC. Burials of V c BC have been found outside the southern wall in Gonio.

AD.
