Khertvisi is one of the oldest fortresses in Georgia and was functional throughout the Georgian feudal period. It was first built in the 2nd century BC. The church was built in 985, and the present walls were built in 1354. As the legend says, Khertvisi was destroyed by Alexander the Great.
In the 10th-11th centuries it was the center of Meskheti region. During the 12th century it became a town. In the 13th century Mongols destroyed it and until the 15th century it lost its power. In the 15th century it was owned by Meskheti landlords from Jakeli family. In the 16th century the southern region of Georgia was invaded by Turks. During next 300 years they have owned Khertvisi too.
At the end of the 19th century Georgian and Russian army returned the lost territories and Khertvisi became the military base for Russian and Georgian troops. Khertvisi fortress is situated on the high rocky hill in the narrow canyon at the confluence of the Mtkvari and Paravani Rivers.
References:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
