Katsuren castle was the residence of the influential Lord Amawari at the time when the Ryukyu Kingdom was still in the stage of stabilization. Amawari resisted until the last moment and destroyed Gosamaru, an important vassal to the king. He tried to usurp the sovereignty by attacking Shuri Castle where the king resided, but instead suffered disastrous defeat and destruction. His defeat brought stability to the sovereignty at Chuzan, with Shuri Castle as its core. Katsuren Castle is designated as a historic site.
