Besleti Bridge

The Besleti Bridge also known as the Queen Tamar's Bridge is a medieval arched stone bridge at Sukhumi, Georgia’s breakaway republic of Abkhazia.

Located some 6 km from the city centre, the bridge spans the small mountain River Besletka, and dates back to the late 12th century. Thirty-five meters in overall length and eight meters high, this single-arch bridge is one of the most illustrative examples of the medieval bridge design popular during the reign of Tamar of Georgia who is traditionally credited to have commissioned the construction of the Beslet bridge. A contemporary inscription in the early Georgian asomtavruli alphabet reads: "Christ the Lord, glorify in every possible way in both lives." An engraved cross and the Greek Τ have survived in the lower part of the left pillar of the bridge.
