Entrance to Nakagusuku Castle
Nakagusuku Castle is a gusuku in the village of Kitanakagusuku, Okinawa Prefecture, Japan. It is now in ruins. The legendary Ryukyuan commander, Gosamaru, built the fortress in the early 15th century to defend against attacks from the east by Lord Amawari of Katsuren Castle. The six courtyards of this fortress with stacked stone walls make it a prime example of a gusuku.
