THE STORY
The story behind the walls
The first builder and foundation date are not securely established. Earlier Nakagusuku lords are considered to have developed it over several generations from the late fourteenth century. Gosamaru moved here around 1440 on royal orders and is credited with extending the northern and third enclosures. After his time, the site continued as an administrative centre into the modern era. It joined the Ryukyu World Heritage group in 2000.
LAYOUT & ARCHITECTURE
Read the landscape and the buildings.
The castle occupies a ridge about 150–170 metres above sea level, using cliffs and steep slopes as defences. Gates control the limited approaches along the ridge, while six enclosures divide the interior. Continuous curves of natural rock and masonry reveal the relationship between stoneworking and terrain.
A CLOSER LOOK
Details worth a closer look.
Three masonry techniques
Compare unworked stones, rectangular blocks laid in courses, and fitted polygonal masonry. Different techniques across the enclosures reveal stages of construction.
Six enclosures
The enclosures reveal a castle developed in stages. Areas attributed to Gosamaru’s additions show that it was not necessarily built in one phase.
Views towards two seas
The site overlooks Nakagusuku Bay and the Pacific to the east, and the East China Sea to the west. The outlook also explains the defensive value of its elevated ridge.
