Jhaishan Tunnel



The Jhaishan Tunnel is a tunnel in Jincheng Township, Kinmen County, Fujian Province, Republic of China. Under the agreement of the Ministry of National Defense, the tunnel can be used by the Republic of China Armed Forces during wartime or for military exercise.

History
The construction of the tunnel started in 1961 and completed on 22 March 1966. Due to the lack of manpower and money to preserve the tunnel, it was closed and abandoned in 1986. Later on, there was a growing interest in preserving the national heritage and remembering those who fought for Kinmen, thus on 23 May 1997, the Kinmen National Park took over the management of the tunnel. The tunnel was opened to the public in 1998.

The tunnel is 101 meters in length, 6 meters in width and 3.5 meters in height. There are seven rooms inside that serve as barracks. The tunnel features an A-shaped waterway with 357 meters in length, 11.5 meters in width and 8 meters in height. It was used to conceal small naval vessels.
