Nong-seong is more than 700 years old, a hill topped with a 12-foot tall earthen wall that extends in a 900-foot oval. Gyeonggi Province officials have recorded that this structure was build by a prominent landowner, Pal Geup Lim, to protect his family from invaders during the Goryeo Kingdom period, 918 to 1392 A.D.
The Japanese pirate invasions of the period also were a strong case for having this type of defensive structure. There is the possibility it was also used to store grain, a practical decision to keep it safe from marauders. There is some mention that it might have continued to be used as a fortress all the way up to 1910. The center of the fortress has 5 areas marked off with small picket fences. Archeologists have determined areas of the fortress that would have contained the ancient structures and you can see the simple division of 4 areas with a central core.
Today this fortress provides a pleasant opportunity to relax and let the eye wander over it's natural beauty. As you enjoy it's walking trails or take the paved path, one of the best pleasures is to climb to the top. After taking in the view, sit inside the center and lean back and rest against the warm earth and soft grasses. You are now far away from any city sights. A pefect spot to relax and return to again and again.
