Deokjusanseong (덕주산성)
& Deokjusa Temple
Deokjusanseong lies in the Woraksan National Park, a gorgeous, protected area of wooded mountain scenery that reminds one of an ancient painting. It’s a strange fortress in that, similar to Mungyeong Saejae, it doesn’t follow the usual circular design. Instead, Deokjusanseong seems to have been premised on a layered or defense in depth scheme protecting Deokjusa Temple up the mountain. The scenery around the castle sites is absolutely breathtaking, making the view from virtually any angle quite incredible!
Constructed during the Unified Silla Period (668-935 A.D.), the castle was, like all those in Chungcheong Province, built to help control the extremely rich Han River Valley near Chungju. Yet its most famous moment came in 1253 when local people mounted its parapets to resist the 5th Mongol invasion. While the battle was a loss, and the fortifications taken, the temple survived.
Deokjusa Temple itself is older, even more scenic, and the subject of much online misinformation. Established by Silla in 586, it was originally called Woraksa. It was renamed near the end of the Unified Silla period after a noteworthy stay by Princess Deokju, daughter of the last king of Unified Silla. Assuming the princess must have established the temple you can find many places online claiming just that. The only problem is the temple was established about 300 years before the royal young lady was born. Regardless, Deokjusa would appear to be one of the oldest, continuously occupied temples in Korea.
