Katsuren Castle

Katsuren Castle (Japanese: 勝連城 Katsuren jō, Okinawan: 勝連城 Katchin gushiku) is a Ryūkyūan castle on Okinawa Island in Katsuren, Okinawa (now part of Uruma). It is a designated UNESCO World Heritage Site.

History
Katsuren Castle was built in the Gusuku Period. Only a few years after Okinawa Island was unified by Ryūkyū, a young lord, named Amawari, came to power in Katsuren Magiri. He grew the number of troops at Katsuren Castle and worried the King of Ryūkyū, Shō Taikyū, who ordered the famous Ryūkyūan general Gosamaru to build Nakagusuku Castle between Katsuren Castle and Shuri Castle. Amawari then accused Gosamaru of plotting to overthrow the King, then attacked and captured Nakagusuku Castle. Gosamaru committed suicide. It was learned then that Amawari was in fact the traitor, and Uni-Ufugusuku, another famous Ryūkyūan general, attacked and captured Katsuren Castle. Amawari was executed.
