The Seiden is the largest wooden structure from the Ryukyu Kingdom and was also referred to as the Kokuden meaning national palace, or Momourasoe-Udun which, as it can be defined, a palace (Udun) that governed the numerous towns (Momo Ura Soe) across the land. The Seiden was the symbol and the most important structure in the kingdom.
The Seiden is a two-layer structure with three floors. This architectural style and the lavishly decorated dragon pillars are unparalleled even in China and Japan, and can be described as something that is very unique to the Ryukyus.
The walls and other painted surfaces of the Shurijo Seiden are coated with tung oil. Parts of the base are lacquer.
This building was destroyed in the fire.
