The Kiyotsu Gorge lookout tunnel is a huge engineering marvel amidst spectacular beauty. Artists and architects recently repurposed it as an art installation replete with reflective surfaces, colored lights and sculptures.
MAD Architects, led by Ma Yansong, has completed the restoration of the Kiyotsu Gorge Tunnel in Japan's Niigata prefecture. The revitalization project sees the installation of several permanent artistic spaces along the historic lookout tunnel, with the intention of bringing back the cultural energy that once empowered the region. The "Tunnel of Light" opened on the occasion of the 2018 Echigo-Tsumari Triennale.
