Wolseong
Gyeongju, South Korea
Wolseong (Hanja, lit. 'moon fortress') or Wolseong Palace was a royal palace of Silla. It was located in what is now Gyeongju, South Korea. The palace was used during the Silla and Unified Silla periods (57 BCE – 938 CE). The palace gets its names from the approximate outline of the palace walls, which were shaped like a crescent moon. It is also called Banwolseong (lit. 'crescent moon fortress') or Sinwolseong or Jaeseong, which means where the king resides.
