11. Olympic Bobsleigh and Luge Track, Sarajevo, Bosnia and Herzegovina
This bobsleigh and luge track, built in 1982, attracted some 50,000 spectators during the 1984 Winter Olympics. But less than a decade after its construction, it was being occupied by Bosnian-Serb artillery units during a civil war. Following the conflict, it became a cycling track in its new official home of Bosnia and Herzegovina. Then in 2014 it was eventually restored for use as a luge training run during the summer months.
10. Negishi Racetrack, Yokohama, Japan
Now that it’s overgrown and silent, it’s hard to believe that Negishi Racetrack in Yokohama once thrummed with the sound of 20,000 spectators during its heyday in the 1930s. In fact, this was Japan’s first Western-type racetrack when it opened way back in 1862. Traditional Western horse racing subsequently thrived here until 1942, when Japan launched itself into World War II. Later, the stables were transformed into cells for captured Australian soldiers. And these days the area is houses American military personnel.
