During the Ryukyu Kingdom, the ancient songs and ballads sung at rites and festivals for the gods were collected into the Omoro-soushi, the classic literature of the era. They were songs for protection of the land and lords, safe sea voyages, and songs of battle. Of the 1554 ballads and songs collected, 67 are songs about Urasoe. Urasoe City chose amongst these and had a modern calligrapher write them out. The pieces were then carved into stone and erected as a monument.
