Shō Shin
Shō Hashi (r. 1422–1439), first king of the unified Ryūkyū Kingdom, made Shuri his capital, and oversaw expansion of the castle and the city. Shuri would remain the royal capital for roughly 450 years. The castle was burned to the ground during succession disputes in the 1450s, but was rebuilt, and the castle and city were further embellished and expanded during the reign of King Shō Shin (r. 1477–1526). In addition to the construction of stone dragon pillars and other embellishments upon the palace itself, the Buddhist temple Enkaku-ji was built on the castle grounds in 1492, the Sōgen temple on the road to Naha was expanded, and in 1501 construction was completed on Tamaudun, which would be used as the royal mausoleum from thence forward.
