Shuri Castle was a Ryukyuan gusuku castle in Shuri, Okinawa Prefecture, Japan. 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. Beginning in 1992, the central citadel and walls were largely reconstructed on the original site based on historical records, photographs, and memory. In 2000, Shuri Castle was designated as a World Heritage Site, as a part of the Gusuku Sites and Related Properties of the Kingdom of Ryukyu. On the morning of 31 October 2019, the main courtyard structures of the castle were again destroyed in a fire.

History
The date of construction is uncertain, but it was clearly in use as a castle during the Sanzan period (1322–1429). It is thought that it was probably built during the Gusuku period, like many other castles of Okinawa. When King Shō Hashi unified the three principalities of Okinawa and established the Ryukyu Kingdom, he used Shuri as a residence. At the same time, Shuri flourished as the capital and continued to do so during the Second Shō Dynasty.

For 450 years from 1429, it was the royal court and administrative center of the Ryukyu Kingdom. It was the focal point of foreign trade, as well as the political, economic, and cultural heart of the Ryukyu Islands. According to records, the castle burned down several times, and rebuilt each time. During the reign of Shō Nei, samurai forces from the Japanese feudal domain of Satsuma seized Shuri on 6 May 1609. The Japanese withdrew soon afterwards, returning Shō Nei to his throne two years later, and the castle and city to the Ryukyuans, though the kingdom was now a vassal state under Satsuma’s suzerainty and would remain so for roughly 250 years.
