On the seashore, 5 km from the city center, near the mouth of the Kelasur River, there are majestic ruins of a huge rectangular tower made of boulders held together with lime mortar. This is the beginning of the Great Wall of Abkhazia, which stretches from the sea through the gorges and mountains of Abkhazia up to the mouth of the Inguri River. Its length is 160 km. The number of towers alone is almost 2,000. Each of them is a small impregnable fortress with a height of 8-12 m with three rows of loopholes. The wall was probably built in the 30s of the 6th century by order of the Byzantine Emperor Justinian and was supposed to protect the country from the invasion of barbarians from the North Caucasus.
We rested nearby. They write on the Internet that this is the third largest fortification in the world after the Great Wall of China and the Gorgan Wall in Iran
