Typhoon Observatory was built on December 3, 1991 by Invincible Typhoon Korean Army. The observatory is situated on Suribong Peak, the highest point of Bikkisan Mountain. It is located 65 kilometers and 140 kilometers from Seoul and Pyeongyang respectively. It is famous in that the location is the closest to the Military Demarcation Line, being only 800 meters and 1,600 meters away from the MDL and North Korean checkpoint respectively.

The observatory houses a Christian church, Catholic church, statue of the Virgin Mary, Buddhist sanctum, belfry and other facilities where soldiers are able to participate in religious ceremonies. Also, Manghyangbi Monument for displaced person, Monument for Korean War, and Boy’s Tank Corps Memorial can be seen in the area. The Exhibition Hall presents daily necessities collected from Pilseunggyo Bridge of Imjingang in North Korea and some detection equipment that armed espionage agents used when they did infiltration after the ceasefire.
