The 4th Tunnel in Inje is a historical site that is shrouded in mystery and intrigue. This tunnel is one of four tunnels that were dug by North Korea during the Korean War in an attempt to invade South Korea. The 4th Tunnel was discovered in 1990 by South Korean soldiers and has since become a popular tourist attraction.
The tunnel is located deep beneath the earth's surface and is approximately 1.7 kilometers long. It is estimated that the tunnel was capable of allowing 30,000 soldiers to pass through it per hour. The tunnel is also 2 meters high and 2 meters wide, making it a tight squeeze for anyone attempting to pass through it.
Visitors to the 4th Tunnel are required to wear hard hats and are not allowed to take any photographs or videos. The tunnel is accessed via a steep incline and a series of stairs that lead down into the darkness. Once inside, visitors can walk along the narrow passageway and see the various artifacts and exhibits that have been placed there.
One of the most interesting exhibits in the tunnel is a model of the tunnel system that North Korea had planned to use to invade South Korea. The model shows the various tunnels and bunkers that were planned, as well as the locations of the artillery and tanks that were to be used in the invasion.
Overall, the 4th Tunnel in Inje is a fascinating and eerie place to visit. It is a reminder of the tensions that still exist between North and South Korea and the lengths that both sides were willing to go to during the Korean War.
