Kinmen Tunnel Music Festival in Zhaishan Tunnel
Since 2009, Kinmen's Zhaishan Tunnel, a Cold War-era underground waterway carved by army engineers throughout the 1960s to shelter military landing craft, has hosted the Kinmen Tunnel Music Festival, using the tunnel's cavernous stone acoustics as a natural concert hall for chamber, choral, and acoustic performances inside a decommissioned wartime structure.
Kinmen sits closer to the Chinese mainland city of Xiamen than to Taiwan's main island, a geographic fact that made it the front line of direct military confrontation during the Second Taiwan Strait Crisis of 1958 and the decades of tension that followed.
