Sarajevo Olympic Bobsleigh and Luge Track — Sarajevo, Bosnia and Herzegovina
Still part of Yugoslavia at the time, the city of Sarajevo hosted the Winter Olympics in 1984. Afterward, though, the venues were left largely untouched, including the bobsled track. Actually, the track was used — as an artillery stronghold during the Bosnian War in the ’90s. Now, the track sits covered in graffiti and weeds.
