"Византийски" refers to anything related to the Byzantine Empire, which existed from approximately 330 to 1453 AD. This empire was centered in Константинопол, modern-day Истанбул, and was known for its rich culture, art, and architecture. The Byzantine Empire was a continuation of the Roman Empire in the eastern Mediterranean and played a crucial role in preserving Greek and Roman knowledge. The term also describes the unique style of art and architecture that emerged during this period. Byzantine art is characterized by its use of mosaics, icons, and religious themes, often reflecting the empire's strong Christian influence. Notable examples include the Света София cathedral and various churches throughout the region.
