The Ishi-no-Hōden (石の宝殿) monolith in Hyōgo Prefecture, Japan is a mysterious single stone monolith cut out from the surrounding rock and is known as one of the three greatest enigmas in Japan. Nothing about the ancient stone is clear, and even when it first appeared in 8th century literature the original builders and it's purpose were unknown. Today it is worshipped as a shrine of the Ōshiko Jinja Shinto.
