Shuri Castle is a historic castle located in Naha, the capital city of Okinawa Prefecture, Japan. It served as the royal palace of the Ryukyu Kingdom from the 15th century until the late 19th century when the kingdom was abolished and Okinawa was annexed by Japan.

Originally built in the 14th century, Shuri Castle was reconstructed multiple times due to destruction from war and fires. The most recent reconstruction was completed in 1992 after the castle was destroyed during the Battle of Okinawa in 1945. The castle features a mix of Okinawan and Chinese architectural styles and was designated as a UNESCO World Heritage Site in 2000.

The castle was used as the center of politics, diplomacy, and culture in the Ryukyu Kingdom. The Seiden, or main hall, served as the king's throne room, while the Ryukyuans also used it as a venue for ceremonies and important meetings. The castle also houses a museum displaying artifacts and documents from the Ryukyu Kingdom, as well as a traditional Ryukyuan dance and music performance hall.

Today, Shuri Castle is one of the most popular tourist attractions in Okinawa and is visited by millions of people every year. It offers visitors a glimpse into the rich history and culture of the Ryukyu Kingdom, and the Okinawan people's way of life before they were assimilated into Japanese culture.
