Shinto's holiest site enshrines Amaterasu, the sun goddess, and houses the sacred mirror of the imperial regalia — which no one, including emperors, may view. Every 20 years, in the Shikinen Sengu ceremony performed since 690 CE, the entire shrine is rebuilt from new hinoki cypress on an adjacent plot, and the old one dismantled: the 63rd rebuilding is scheduled for 2033. The buildings are always new; the building is 1,300 years old. It is the opposite strategy to the pyramids — and it has outlasted most of them culturally intact.
