Zhaishan Tunnel

A wartime waterway carved through granite, where music echoes through caverns
📍 Kinmen · Jincheng Township · Gugang⛩️ Historic Sites & Temples🔖 Military Tunnel · Waterway Engineering · Music Performances

Completed in 1961, Zhaishan Tunnel was manually carved by soldiers through a granite formation. The tunnel stretches 357 meters and was designed to allow small landing craft to enter and exit covertly for resupply during wartime. After the Cold War ended, this waterway reopened in a very different role — as Kinmen's one-of-a-kind underground concert hall and historical site.

Highlights of Zhaishan Tunnel

The tunnel consists of an A-shaped waterway tunnel and a land passage. The A-shaped waterway is approximately 101 meters long and tall enough to accommodate small boats. The rock walls preserve the tool marks left by hand-carving, making them direct physical evidence of military engineering history. The entire project was completed by a large workforce under extremely demanding conditions in a very short time.

After the tunnel was opened to tourism, it began hosting regular music concerts, and the natural reverberation of the granite cavern gives the sound a unique acoustic character. Even outside of performance times, visitors can walk inside to experience the tunnel's scale and observe the water level and rock wall texture. The exhibition area displays historical materials about the tunnel's construction, explaining its building background and military function.

Tips for Getting the Most Out of Your Visit

🎵
Check Performance Schedules Before Planning Your TripMusic performances are not held on a fixed schedule. Check official announcements from Kinmen National Park in advance. Attending during a performance makes the acoustic experience of the tunnel noticeably different from a regular visit.
🪨
Look for the Chisel Mark PatternsThe rock walls preserve the regular groove patterns left by the chisels used during construction, showing the precision and methods of manual labor. These represent a cultural engineering heritage of the tunnel beyond its military significance.
🚤
Understand the Logic of the Waterway DesignThe A-shaped waterway is designed so that a craft can enter from the sea side, moor inside the tunnel, and then exit from the other side. Referring to a map to understand the tunnel's relationship to the coastline helps clarify its strategic function.
🧥
Bring a Light JacketThe interior of the tunnel is consistently cooler than the outside air and has higher humidity. Even in summer, a light jacket is recommended.
