Shuri Castle (首里城, Shuri-jō, Okinawan: Sui Gushiku) is a Ryukyuan gusuku in Shuri, Okinawa. Between 1429 and 1879, it was the palace of the Ryukyu Kingdom, before becoming largely neglected. In 1945, during the Battle of Okinawa, it was almost completely destroyed. After the war, the castle was re-purposed as a university campus.
