Gonio Castle

Gonio fortress is a Roman fortification in Adjara, Georgia, on the Black Sea, 15 km south of Batumi, at the mouth of the Chorokhi river. The village sits 4 km north of the Turkish border. Its name was connected with the myth of Medea and her brother Absyrtus.
It later came under Byzantine influence. The name "Gonio" is first attested in Michael Panaretos in the 14th century. In addition, there was a short-lived Genoese trade factory at the site. In 1547, Gonio was taken by the Ottomans, who held it until 1878, when, via the San-Stefano Treaty, Adjara became part of the Russian empire. In the fall of 1647, according to Evliya Çelebi, Gonio was captured by a Cossack navy of 70 chaikas, but quickly recovered by Ghazi Sidi Ahmed, ruler of the Tortum sanjak, with a force of 1,000 Turks and 3,000 "Mingrelians".
