Rio is blazing in glory and colour as the Olympic Games get into full swing.
But other Olympic cities, which have hosted the Games in years gone by, look vastly different: deserted, abandoned, and derelict.
These pictures capture how parts of former host cities such as Sarajevo, Athens and even Beijing as recently as 2008 fell into complete disrepair once the Games were over.
In some of these images, it is hard to believe it was just a matter of years ago when thousands watched as Olympians took to the stage across these venues.
