Incredibly beautiful medieval cave city Vardzia, which was built in the 12th century by Georgia’s greatest ruler -Queen Tamar, is located in Georgia’s southern Samtskhe-Javakheti region, 60km from Akhaltsikhe. Vardzia monastery is simply amazing and breathtaking, with unusual location. This city once used to have 30,000 inhabitants  – now it’s a monastery where several monks live. Most of the city museum is open to the visitors and you can visit the caves and the main cave church with well-preserved frescoes, including the fresco of Queen Tamar and his father King George III) from the 12th century. It involves some walking on the steps, in the dark tunnels too.
