The Potskhovistsqali River

The Potskhovistsqali River: A Transboundary Waterway of Meskheti

The Potskhovistsqali River (მდინარე ფოცხოვისწყალი) is a significant transboundary river that flows through northeastern Turkey and the Samtskhe-Javakheti region of southern Georgia. It rises in Turkey from the Yalnızçam Mountains, where it is known as the Posof Çayı. The river crosses the border into Georgia and carves a deep, scenic valley through the historic Meskheti region before joining the Mtkvari River as a major left tributary near the city of Akhaltsikhe.

The river valley is a place of considerable historical and cultural importance. It flows directly past the iconic Atskuri Fortress, one of the most important medieval strongholds in Georgia, which guarded the entrance to the Borjomi Gorge. The river has been a lifeline for the region for millennia, sustaining numerous settlements, including the city of Akhaltsikhe, the administrative center of Samtskhe-Javakheti. Its journey through a landscape dotted with fortresses, monasteries, and ancient settlements makes the Potskhovistsqali a central artery of Meskhetian history and geography.
