Agarani Fortress, Medieval fortress in Kojori, Georgia.

Agarani Fortress stands on Azeula Mountain at 1351 m on the Didi Kedi Range, part of the Trialeti mountains. Its ruins consist of a circuit wall with two towers at the southwest and northeast ends, built of rubble stone and brick. The oldest layer dates to the second half of the 11th century, while the surviving wall fragments are from the 16th to 18th centuries.

Agarani appears in The Georgian Chronicles, though its construction date is unknown. In 1080, during the Great Turkish Invasion, it was taken and acquired the name Kor Ogli, still used on Soviet topographic maps. In July 1118 David the Builder besieged and took it in one day, granting it to Ivane Orbeli in 1123. In 1177 nobles rebelling against George III fortified themselves here until the king retook it.

The fortress reflects Georgian feudal architecture from the 11th century with walls and towers typical of that era. These structures allow visitors to understand how medieval builders thought about defense and settlement.

The fortress sits approximately 20 kilometers southwest of Tbilisi and is accessible by car along the road toward Kojori. The climb up the hill requires some fitness, but rewards you with views across the surrounding countryside.

The site hosted visits from high-ranking Georgian rulers who spent time there for administrative matters and personal rest. These stays show that the place was both strategically important and valued as a retreat.
