Byzantine style

Byzantine architecture is the architecture of the Byzantine Empire, also known as the Later Roman or Eastern Roman Empire. Byzantine architecture was mostly influenced by Roman and Greek architecture and later Sassanian and Islamic influences to an extent. 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.

Early Byzantine architecture drew upon earlier elements of Roman architecture. Stylistic drift, technological advancement, and political and territorial changes meant that a distinct style gradually resulted in the Greek cross plan in church architecture.

Buildings increased in geometric complexity, brick and plaster were used in addition to stone in the decoration of important public structures, classical orders were used more freely, mosaics replaced carved decoration, complex domes rested upon massive piers, and windows filtered light through thin sheets of alabaster to softly illuminate interiors. Most of the surviving structures are sacred in nature, with secular buildings mostly known only through contemporaneous descriptions.
