The remains of Tanakura Castle are located in Tanagura, Higashi-shirakawa, Fukushima Prefecture.

Nagashige Niwa, who was moved to Tanagura, was given an order, by the Second Shogun Hidetada Tokugawa in the first year of the Genwa era (1622), to build a castle. Shigetada then moved Chikatsu Shrine to Baba in the first year of the Kanei era (1624), and in the next year, started construction of the castle on the former site of the shrine.

Tanakura Castle was completed in the 4th year of the Kanei era (1627), but unfortunately, Nagashige was sent to a different land. The castle lord has since changed repeatedly, and, by the Meiji period, 8 families had ruled for 16 generations.

After enduring attacks from the Imperial Army during the Boshin Wars in the 4th year of the Keiou era (1868), the castle was burned down and surrendered to the enemy by the castle lord himself.

The former castle keep was turned into Kamegashiro Park in 1948. In the Edo period, Tanakura Castle was used as land for transferring lords who had been demoted, but even that has become part of history.
