Besleti Bridge

The Besleti Bridge, also known as the Queen Tamar Bridge, is a medieval arched stone bridge at Sukhumi, Georgia's breakaway republic of Abkhazia. The bridge spans the small mountain River Besletka, and dates back to the late 12th century.
This single-arch bridge is one of the most illustrative examples of the medieval bridge design popular during the reign of Tamar of Georgia (1184-1213) who is traditionally credited to have commissioned the construction of the Besleti bridge.
