Early Byzantine architecture is essentially a continuation of Roman architecture. Examples include the walls of Byzantium and Yerebatan Saray. A frieze in the Ortrogothic palace in Ravenna (now S Apollinare Nuovo) depicts an early Byzantine palace.
Gradually, a style emerged which was influence more by the architecture of the near east, and used the Greek cross plan for the church architecture which mostly stands today. Brick replaced stone, classical orders were used more freely, mosaics replaced carved decoration, and complex domes were erected.
Ultimately, Byzantine architecture in Italy gave way to the Romanesque and Gothic architecture, while in the east it informed early Islamic architecture.
Neo-Byzantine architecture had a small following in the wake of the Neo-Gothic of the nineteenth century.
Great works of Byzantine architecture include:
