Nakagusuku Castle

Nakagusuku Castle (Japanese: 中城城 Nakagusuku jō, Okinawan: 中城 Nakagushiku) is a Ryūkyūan castle on Okinawa Island in Kitanakagusuku, Okinawa. It is a designated UNESCO World Heritage Site.

History
Nakagusuku Castle was built around 1458 by Gosamaru, a famous Ryūkyūan general, to intimidate the lord of Katsuren Castle, Amawari, who had worried the King of Ryūkyū with his growing power. In 1458, Amawari accused Gosamaru of plotting to overthrow the King and attacked and captured Nakagusuku Castle. Gosamaru committed suicide. Amawari was later caught and executed. In 1851, Commodore Matthew Perry visited the castle, which was recorded as "the fortress of Nagagushku". It was noted for its size and the fact that its walls were made in a style that resisted cannon fire.
