Dahan Stronghold, Military complex in Nangan, Taiwan
Dahan Stronghold is a granite fortification on Nangan Island featuring a tunnel network with gun emplacements and observation posts positioned along the coast. The structure integrates into the natural landscape, using the rocky terrain to create multiple vantage points for maritime surveillance.
The stronghold was carved into solid rock during the 1970s using traditional labor methods and completed in 1976. It was built to maintain strategic control over the Taiwan Strait during a period when coastal defense was a primary concern.
The stronghold represents to local residents a tangible reminder of when armed tension defined daily island life. Visitors walking through the corridors today sense the vigilance that soldiers once maintained while stationed in these rock-carved chambers.
Wear sturdy footwear since the tunnel paths are uneven and feature steep stairs in several sections. The colored lighting throughout the corridors helps with navigation, making it easy to explore the site independently.
The interior passages are lit with colored LED installations that give the austere concrete tunnels an unexpectedly modern, almost surreal appearance. This artistic lighting was added years after the site's original construction, creating an unusual fusion of military history and contemporary art.
