On the other side of the stone walls to the south of Shicha-nu Una is Kyo-no Uchi, the largest area within the castle grounds for religious ceremonies.
The location is said to be the place of origin of Shurijo Castle. Here, Kikoe Okimi, the highest priestess of a faith that was unique to the Ryukyus, and the three priestesses, Oamushirare, prayed to the gods for the prosperity of the royal family, safe voyages, and abundant harvests.
