Glowworm Tunnel - 2 Vera St, Helensburgh, Australia

The official name for this is the Metropolitan Tunnel, built in the 1980s. It was only used until 1915 due to the collection of smoke and soot from the trains passing through. The tunnel regularly gets flooded, but a glowworm colony took over the tunnel and made a home on the roof. When walking through, it is like looking at a constellation of blue and green stars.
