These pictures of post-Olympic ruins show a fate that must never be allowed for London.
The pictures on the excellent Flavorwire website are from an exhibition called The Olympic City by photographer Jon Pack and filmmaker Gary Hustwit.
The Paralympics opens tonight, but in 12 days time London's time in the Olympic spotlight will come to an end.
Organisers insist that London's Olympic and Paralympic legacy is more secure than any previous host city with organisers placing as much emphasis on planning for the future as hosting the Games itself.
One example is that several of the venues for London have been built as temporary structures, particularly for sports that do not have a strong following in this country such as basketball and beach volleyball.
And the choice of the location for the Olympic Park itself is also cited with billions of pounds now pouring into an area of East London which was previously one of the poorest areas in Europe.
But let these pictures be a warning that, at this stage, the job is only half done.
