Khertvisi was repeatedly rebuilt. In 1356-1356, Zakaria Kamkamishvili, Treasurer of the King, built the tower and wall. In the XVI century the fortress belonged to the feudal family Hertvisari. In 1578 the Turks captured Khertvisi with other fortresses of Samtskhe – Saatabago. In 1828-1829, after the victory of Russia over Turkey, the fortress was returned to Georgia. At that time, Khertvisi, along with other Georgian fortresses, lost its strategic importance.
