were painted in red with lacquer, walls and eaves colorfully decorated, and roof tiles made of Goryeo and later red Ryukyuan tiles, and the decoration of each part heavily using the king's dragon. Given that the Nanden and Bandokoro were both used for reception and entertainment of the Satsuma clan, a Japanese style design was used here only. Ryukyuan elements also dominate. Like other gusuku, the castle was built using Ryukyuan limestone, being surrounded by an outer shell which was built during the Second Shō dynasty from the second half of the 15th century to the first half of the 16th century. Similarly, Okushoin-en is the only surviving garden in a gusuku in the Ryukyu Islands, which made use of the limestone bedrock and arranged using local cycads. The current renovation is designed with a focus on the castle's role as a cultural or administrative/political center, rather than one for military purposes. The buildings that had been restored as original wooden buildings (and subsequently destroyed in the 2019 fire) were only in the main citadel. The Seiden was rebuilt using wood from Taiwan and elsewhere after rituals blessing the removal of large trees from mountains in the Yanbaru region of Okinawa took place. Other buildings, such as the Nanden or Hokuden were only restored as facades, with interiors made using modern materials such as steel and concrete. Old walls remain in part, and were excavated and incorporated during the construction of the new castle wall, forming the only surviving external remains of the original castle. Sites of interest Due to its central role in Ryukyuan political and religious life, Shuri is composed of and surrounded by various sites of historical interest. The castle complex itself can be divided into three main zones, namely a central administrative area (including the Seidan and Ura), an eastern living and ceremonial space (behind the Seidan) called the Ouchibara (literally "inside field"), and a southwestern ceremonial area including the Kyo-no-uchi (literally "inside capital").
