Gosamaru committed suicide here in 1458 after being falsely accused of treason by his rival, Amawari.
The castle features one of the few surviving examples of the 'nozura-zumi' stacking technique, which predates the more polished masonry styles found elsewhere.
Commodore Matthew Perry visited these ruins in 1853 and noted the superior quality of the stonework in his expedition journals.
The castle’s layout was intentionally designed to follow the natural ridges of the hill to maximize defensive capabilities.
Excavations revealed Chinese porcelain shards, indicating that the castle was an active participant in regional maritime trade.
The base of the castle walls is significantly wider than the top, a structural design feature that provides high resistance against earthquakes.
Nakagusuku Castle Ruins is a UNESCO World Heritage site representing the Gusuku period of the Ryukyu Kingdom. Built by the famous commander Gosamaru in the 14th century, the castle is renowned for its sophisticated stone masonry techniques, specifically the 'aikata-zumi' style where stones are fitted together like a jigsaw puzzle. The fortress sits on a 160-meter-high limestone cliff, providing panoramic views of both the Pacific Ocean and the East China Sea. It consists of six distinct baileys connected by arched gates, showcasing the evolution of Okinawan defensive architecture. Unlike many other Ryukyuan castles, a significant portion of its original walls remain intact due to the hardness of the local rock. The site is part of the 'Gusuku Sites and Related Properties of the Kingdom of Ryukyu' World Heritage serial nomination. Archaeologists have identified residential areas within the castle complex that suggest a complex social hierarchy during its peak. The ruins are characterized by their integration with the natural karst landscape, utilizing natural rock formations as part of the defensive perimeter.

Wear sturdy walking shoes with good grip as the limestone paths can be uneven and slippery when wet.
Bring a hat and sunscreen, as the ridge location provides almost no shade while walking the ramparts.
Start at the highest point of the site to get an immediate overview of the layout before exploring the individual baileys.
Do not attempt to explore the abandoned hotel site located nearby, as it is private property and structurally unsafe.
Do not climb or sit on the historical stone walls; stay on designated paths to preserve the integrity of the ruins.
