In-depth articles also cover Earth's largest Buddhist monument, Borobudur, in Indonesia; the oldest wooden buildings located at Japan's Buddhist temple site of Horyuji; Earth's most remote, inhabited island, Rapa Nui, aka Easter Island; and one of Christendom's oldest churches, Palestine's Church of the Nativity in Bethlehem.
