Gongsanseong

Gongsanseong is a mountain fortress in South Korea that served as a royal palace and defensive fort during the Baekje period. This commanding stone structure is a UNESCO World Heritage site and offers much to explore, along with some superb views over the town and the Geumgang River.
There are two ways to tour the fortress; one is to start from the parking lot, passing the west gate before following the road around, the other is to walk along the top of the castle via Sanseong Road. The latter route has many twists and turns and is a more challenging trek, but it also has the advantage of following alongside the river.
There are numerous pavilions scattered around the site that have been sympathetically reconstructed according to archeological evidence. A changing of the guards ceremony takes place at the main entrance between 11am and 4pm on weekends throughout April, May, June, September and October. Every evening the fortress is lit up by floodlights.
