And in the air about him were great viperine creatures, which had curiously distorted heads, and grotesquely great clawed appendages, supporting themselves with ease by the aid of black rubbery wings of singularly monstrous dimensions.
--August Derleth
Kakinohana gusuku is a fortress in the town of Tamagusuku. The castle is famous for its spring, Kakinohana-hija, which is essentially the terminus of an underground river, or system of springs, that runs from Hedo no Misaki, the northernmost point on the island, through Shuri, and then down to Kakinohana, where, heedless of rain or drought, water gushes forth from the bottom of the cliffs below the castle.
The fortress is small, with just two enclosures. The stone walls, believed to have been built by the second son of Minton anji (the Lord of Minton) are made of piled up uncut stone, though watchtower foundations in cut, stacked stone also remain on the northern and southern ends of the site. The site is today shielded from the sun by dense tree cover, but it is unclear whether this was the case when the fortress was actively in use.
As at most gusuku, the site contains a shrine, in this case to the god Afuihanateru-tsukasa-no-oibe, and a tomb for the anji of the castle.
