Neo-Byzantine, or Byzantine Revival, is the revival of Byzantine art and architecture that emerged in Western Europe in the 1840s and peaked in the last quarter of the nineteenth century. It reaches back to the Christian architecture of Constantinople and Ravenna - domed and pendentive churches, Greek-cross plans, brick-and-mosaic surfaces - and redeploys it for churches, public buildings, and institutions. Paul Abadie's Sacré-Cœur in Paris made it famous; monumental cathedral building carried it across the Russian Empire and Bulgaria, and Russian emigré architects kept it alive in interwar Yugoslavia. In painting and decoration the revival likewise returned to Byzantine models: gold-ground icons, mosaics, and hieratic figures, often fused with Art Nouveau or national revival idioms. Its afterlife stretches worldwide, from Washington's National Shrine to Orthodox churches built today.
