Abandoned Hotel In Colombia
What once may have been an incredible tourist destination is now a dangerous ghost town. The hotel, once renowned for its beauty, sits on a cliff above the Bogota River. The hotel had to close when the river became polluted with industrial waste and the entire area became chaotic.
Old Helensburgh Railway Tunnels
Connecting various parts of Australia, the Helensburgh Tunnels were constructed in the 1880s. Instead of going around the hilly terrain, these tunnels go straight through it. Less than 30 years after their construction, however, they were decommissioned in favor of a two-way rail network. The historic ones are still open for tourism.
