The monastery has existed since the 9th century. At the end of the 13th century, Sapara became the possession of the Jakeli family. The ruler of the principality, Sargis Jakeli, managed to maintain good relations with the Mongols by skillful diplomatic manipulations, which made his reign peaceful and further strengthened the position of the principality. At the end of his life, Sargis took monastic vows and changed his name to Saba (Sava). His son Beka built the largest of the 12 churches here, the Church of Saint Sava, named after his father's patron saint, one of the most architecturally significant churches of its time. Its 14th-century frescoes have been perfectly preserved to this day and are of great cultural importance as an example of the culture of that time. The frescoes depict, in particular, portraits of the Jakeli princes and in three registers scenes from the Old and New Testaments.
From the end of the 16th century to the beginning of the 17th century, the Sapara Monastery was empty due to the expansion of the Ottoman Empire in Samtskhe. In 1877-1878 the monastery was destroyed by Muslims, in 1893 it was restored.

This is one of the most ancient fortresses of the Georgian Middle Ages. It is located on a high rocky hill in a gorge at the confluence of the Kura and Paravan rivers. Chroniclers of the Middle Ages wrote in their chronicles that one of the first large cities of Georgia stood on this site, since it is mentioned in connection with the campaign and movement of part of the troops of Alexander the Great in the Caucasus. The bulk of the buildings of the complex that have survived to this day date back to the 10th-14th centuries, as well as small extensions of the 16th-18th centuries. The fortress of Khertvisi, as well as the fortress of Akhaltsikhe Rabat, was controlled by the Ottoman Empire from the 16th to the beginning of the 19th century.
