War tore apart the city that hosted the 1984 Winter Olympics - here's what the abandoned venues look like today

Dado Ruvic/ReutersA view of the disused ski jump from the Sarajevo 1984 Winter Olympics on Mount Igman, near Sarajevo, Bosnia.On February 8, the 2018 Winter Olympics will kick off in Pyeongchang, South Korea. The country has devoted over $1 billion toward building gleaming new stadiums and slopes.

For Olympic host cities, this kind of major investment is not unusual. But after the world's TV sets tune out, some of these cities do not have the infrastructure for upkeep of the venues. In the case of Sarajevo, Bosnia, some Olympic sites were torn apart by war.

Sarajevo hosted the 1984 Winter Olympics, but a decade later, terrible conflict ravaged much of the city and killed thousands of civilians.

Today, many of the former venues lie in ruin.
