The Byzantine period is undoubtedly an important link between the Balkan countries. Bulgaria, Serbia, North Macedonia and Northern Greece in particular have some of the best examples of Byzantine art, represented in the many churches and monasteries. Great Byzantine emperors such as Galerius and Constantine the Great were born in the territory of today's Serbia, who also ruled from Serdica, where we will visit some of their works. We will also travel to Thessaloniki and Meteora and see the heritage on the shores of Lake Ohrid.
