Nanshan Tou No. 4 Camp

Nanshan Tou No. 4 Camp, which opened for public visits in early 2018, is Lieyu's southernmost coastal military outpost. Inside the camp, there are 2 artillery bunkers, 7 underground pillboxes, and 1 command post. The tunnels are also an unmissable part; they reach a depth of 3 stories, and their layout and structure are rarely seen among Kinmen's numerous tunnels.
