The area was officially decommissioned as a railway line before being renovated into a tourist attraction.
Twin Tunnel is a repurposed railway tunnel system in Miryang that serves as an indoor light-themed attraction. The facility utilizes two parallel tunnels originally built in 1904 for the Gyeongbu Line railway. The interiors are permanently installed with millions of LED lights, projection mapping, and themed character displays. The walking path spans approximately 900 meters in length, maintaining a cool microclimate regardless of outdoor weather. It features seasonal thematic changes to its light displays and decorative structures. The site occupies the space of the former Samrangjin-Majeon rail line.
