Located by Tieban Bay on Nangan Island, Nangan Beihai Tunnel is one of the most representative military engineering projects of Matsu's wartime culture. The tunnel was hand-carved along the granite cliffs during the wartime era, forming winding underground waterways capable of docking multiple supply boats. Its massive scale and intricate structure demonstrate the resilience and defense needs of the past wartime period. Today, the Beihai Tunnel has been transformed into a major tourist attraction, where visitors can walk along the pathways into the tunnel's interior, experiencing the magnificent rock walls, the echoes of the tides, and the profound military atmosphere.
