The Church of the Nativity, located in the heart of Bethlehem, is the most sacred site in the Christian faith, the birthplace of Jesus Christ, marked by the Church of the Nativity. This, of course, is no ordinary church; the entryway is extremely small, while inside, visitors are exposed to a vast nave and beautiful mosaics and artwork. The Nativity Church Bethlehem is not only the oldest church in Israel, but it is one of the oldest continuously operating churches in the world.
Church of the Transfiguration, Kizhi Island, Karelia, Russia, 1714, based on a greek cross plan, with an octagon used at the crossing. Instead of a tent roof at the the Church of the Nativity, Onion domes are used (reverse curve gables - bochki). Influenced by S Sohpia in Kiev - using domes to create compartmentalized spaces invisible from the outside.
