Byzantine architecture

Byzantine architecture is the architecture of the eastern sphere of the later Roman Empire, developing from late Roman and early Christian antecedents in the 5th century and influencing church building in Greece, Italy, and elsewhere for more than a thousand years; characterized by masonry construction, round arches, shallow domes carried on pendentives, and the extensive use of rich frescoes, coloured glass mosaics, and marble revetments to cover whole interiors.
