The Sarajevo Olympic Bobsleigh and Luge Track was built on Trebević mountain overlooking the city of Sarajevo for the 1984 Winter Olympics. The track could hold up to 30,000 spectators and after the Winter Olympics, it continued to be used for World Cup competitions.
However, with the start of the Yugoslav wars in 1991 that would include the Bosnian War the following year, the track was no longer used. The track was damaged as a result of Siege of Sarajevo and during the siege, the track was used as an artillery position by Bosnian Serb forces.
Today, the tracks still remain mostly intact with war wounds of defensive fighting holes, drilled into one of the last turns of the course.
