Wolseong is a tourist site in central Gyeongju where visitors walk around the remains of a Silla royal palace and its moat. A crescent-shaped earthen rampart runs along the site, and from it the moat, Cheomseongdae, and the direction of Gyerim can be seen together. On Fridays the excavation site is opened to the public and explanations are provided. Parts of the area are currently closed because of the ongoing excavation.
