Iron Fort is a military position carved into a reef off Nangan's Tieban Village, officially designated "Nangan Position 51" and built by blasting and hollowing out the granite reef, completed around 1976. After wartime military administration ended in 1992, it was opened to the public during Commander Jin Enqing's tenure; it is one of the few isolated reef outposts in Matsu once guarded by military dogs, and its original sleeping quarters, kitchen, and gun ports remain preserved.

What to See at Iron Fort
The site's logic lies in its reef location, which is naturally difficult to approach; the surrounding sea-eroded gullies serve both as a terrain barrier and a defensive advantage. The interior space was carved out by blasting, a raw and effective method, leaving bare rock walls as interior surfaces. The gun ports face toward the strait, allowing effective surveillance of vessel movements in the surrounding waters. At low tide, visitors can cross the stone bridge onto the reef itself and walk inside the pillbox, experiencing its extremely cramped garrison quarters firsthand.
The kitchen, sleeping quarters, and other living facilities inside the fort share the same narrow space as the gun ports, highlighting the everyday reality of soldiers stationed in extreme conditions. The sea-eroded gully terrain surrounding the reef is also worth observing — channels and cavities worn into the granite by years of wave action create an interesting coastal erosion landscape. At high tide, the stone bridge is submerged and the reef becomes a true island; plan your visit to coincide with low tide.
