Tsuruga Castle (???, Tsurugaj?) was built in 1384 and changed hands many times between the different rulers of the Aizu region. It was destroyed after the Boshin War of 1868, a rebellion against the newly formed Meiji government, which had taken over control from the Tokugawa shogun and put an end to Japan’s feudal era. Tsuruga Castle was one of the last strongholds of samurai loyal to the shogunate.
The castle was rebuilt as a concrete reconstruction in the 1960s.
