Dahan Outpost is a Cold War coastal artillery position on a cliff above Renai Village, Nangan, with tunnels totaling 230 meters (a 150-meter main tunnel plus an 80-meter branch tunnel); it was excavated by hand in 1975 by soldiers of the Matsu Defense Command's Dengbu unit and completed on March 29, 1976, with four 90mm anti-aircraft gun positions inside. After renovation, it opened to the public in February 2007, and visitors can enter via the walkway beside the Nangan Visitor Center.

What to See at Dahan Outpost
The outpost was sited on the sea cliff along Nangan's northern coast, a position that commands the entrance to the shipping lane with excellent elevated firepower. The tunnels were carved following the cliff contour, with a battery of gun ports facing the strait that could directly engage passing vessels. During the Cold War, when cross-strait traffic in the shipping lanes was fraught with tension, coastal outposts like this were critical nodes in Matsu's defensive network; Dahan Outpost is one of the more representative front-line relics on Nangan in terms of both scale and state of preservation.
The artillery, ammunition storage spaces, and communication facilities displayed inside the tunnels together present a complete picture of a front-line outpost. The walkway extends along the cliff face with multiple viewpoint nodes offering different angles onto Renai Beach, Beigan Island, and the surrounding waters. When morning or evening light falls obliquely on the sea, the scene is richly layered — an ideal time for photography. The interior of the tunnel is relatively dark; bring a flashlight.
