The Roman fortresses of Kaleto and Daran Baran are situated 500 metres south of the village of Krushuna and approximately date back from 2nd c. BC. They say they used to be an important strategic barrier for Romans against the tribes of the Goths, Carpi, Sarmatae, Vandals and Slavs, invading from the north. To visit them, you have to follow the Krushuna – Karpachevo Trail. The sites where they were constructed are not accidental. They were intentionally close to major imperial roads. These roads were used to transport food from the rich provinces to the capital and stoneware and pottery in the opposite direction. It is widely known that these regions used to supply animals, grain and wine for the endless feasts in Rome.
