Dahan Stronghold

Dahan Stronghold is located near the Beihai Tunnel (北海坑道) and Nangan Tourist Center (南竿遊客中心) and is a strategically important tunnel on the south coast of Nangan Island in that it controls the waterways near Juguang Island (莒光島) to the south. Compared to the Beihai Tunnel, where boats can pass inside the tunnel, Dahan Stronghold is relatively simple. Originally built for military purposes, and created with dynamite explosions, most of it has been excavated with human labor. If you touch the cold, hard tunnel with your palm, it is as though you are feeling the suffering that went into its construction.

The stronghold is divided into three floors. After you walk into the entrance, you will find yourself on the lowest floor, where you can see the briefing room, Zhongshan room (中山室), warehouse and depots. At the end of the tunnel, there are some retired machine gun forts that have rotted on the outside and are pointed at the boundless sea. Here, you can feel a deep sense of the ephemeral nature of life. Walking upwards from the end of the tunnel, you will reach the middle floor which is for machine guns and an upper floor for military offices. The tunnel is 1.5 meters wide, 2 meters high and 150 meters long. On a clear day, Juguang Island is visible in the distance.
