Byzantine Architecture is the architecture of the Byzantine Empire, also known as the Later Roman or Eastern Roman Empire. This terminology is used by modern historians to designate the medieval Roman Empire as it evolved as a distinct artistic and cultural entity centered on the new capital of Constantinople rather than the city of Rome and environs. The empire endured for more than a millennium, dramatically influencing Medieval architecture throughout Europe and the Near East, and becoming the primary progenitor of the Renaissance and Ottoman architectural traditions that followed its collapse.
Byzantine art is the name for the artistic products of the Eastern Roman (Byzantine) Empire, as well as the nations and states that inherited culturally from the empire. Though the empire itself emerged from Rome's decline and lasted until the Fall of Constantinople in 1453, many Eastern Orthodox states in Eastern Europe, as well as to some degree the Muslim states of the eastern Mediterranean, preserved many aspects of the empire's culture and art for centuries afterward.
