In the south of the country, not far from the famous cave town of Vardzia, at the confluence of the Paravani and Mtkvari rivers, there is a popular attraction, the fortress of Khertvisi. The ancient fortress perfectly matches nature: Surrounded by mighty mountains, the muscular walls look even more powerful. The date of the construction of the defense in different sources is indicated in different ways. The first mention of it was back in the time of the Great Silk Road. The castle is located on the top of the mountain and, at one time, was difficult to access. That's why Khertvisi is kept in good condition.
