Kinmen Zhaishan Tunnel & Deyue Tower

Subterranean granite military canal carved by hand following the 1958 artillery war, reflecting emerald waters.

Chiseled deep into solid granite following the 1958 Second Taiwan Strait Crisis, Zhaishan Tunnel in Kinmen served as an invulnerable underground harbor for military supply boats. The massive cavern opens directly to the sea, where calm turquoise waters mirror rugged rock walls in ethereal tranquility. Pair with a visit to Shuitou Village's historic Deyue Gun Tower and Minnan swallowtail courtyards.
