The only cave in Korea to use a train to view the inner side of the tunnel, the 4th tunnel
The 4th Tunnel was discovered on March 3, 1990. It is located 1,200m from the Military Demarcation Line in the demilitarized zone of South Korea. This is the only tunnel to be discovered that provides full access to tour groups. Educational instruction is given in the square outside the tunnel. Around the entrance, there are many safety centers and monuments including military equipments. Among them all, the most noticeable is the statue of the military dog, ‘Hunt’. Hunt is an investigatory dog that died during the process of exploring the 4h tunnel. It saved the life of a squad, in which it stepped on a North Korean mine. There are no ranks for military dogs, but Hunt was declared as a lieutenant by his death. The safety education center has a theatre and exhibition hall with a capacity of 200 people. Plus, the 3D projector featuring the North Korean tour sites enables easier understanding of North Korea.
