Gagra
In the time of the Roman Empire the town was renamed to Nitica. Because of its geographical and commercial importance, it was attacked repeatedly by the Goths. The Romans did not neglect it, however. They fortified it well. After the Romans, the Byzantine Empire took control of all of Colchis, including Nitica. It became a major trading center for merchants from Venice and Genoa. The name "Gagra" appeared for the first time on a map in 1308. This was on a map of the Caucasus made by the Italian Pietro Visconti. This map is now in the Library of Saint Mark in Venice.
