“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.” Click here for photo gallery from Business Insider.
