Boblsed track, ski jump, hotels -- 1984 Winter Games; Sarajevo, Bosnia and Herzegovina
By far the most haunting (and admittedly depressing) ruins, the war-torn remnants of the '84 Games outside Sarajevo on the Trebevic and Igman mountains saw heavy fighting during the Bosnian War. You can still tour everything, from ski jumps and crumbling concrete hotels to the bullet-ridden medal podium and graffiti-covered bobsled/ luge track, which cost $4.5 million to build at the time.
Despite having just
hosted the '72 Winter Olympics, Sapporo came right back in '77 and bid for the '84 Games; they were narrowly edged out by Sarajevo on a second vote. Ever heard of sharing, Sapporo!? Surprisingly, in 2003 Sarajevo actually bid to host the 2010 Winter Games and promised to fill in all
the bullet holes while rebuilding some the current facilities; they didn't make the short list.
