Sazaedo was built on Mt. Hanseizan in 1796. It is an unusual, hexagonal, three-story temple that is 16.5 m tall. Just as with Tsuruga Castle, it is a symbolic tourist attraction in Aizu-Wakamatsu and is usually packed with tourists. Sazaedo has a double-helix structure, whereby the walkway up and walkway down are entirely different routes, making it a one-way path. It uses an architectural style, which is rare in the world, that allows worshipers to safely pray without having to double back and pass each other. It has been recognized as historically unique architecture, and in 1996 it was designated as an important national cultural property.
