Very sad to see this kind of decay of a major structure that was once important, and a symbol of something thriving. The Olympics are strange, though... it's great prestige for a a place to host the Games, but most of the host cities don't actually need many of the facilities built for the occasion. I suppose the secret — if there is one — is to repurpose the structures for something actually relevant to the community.
Nice juxtaposition of the shiny new with the decay!
It would be interesting to see how different host countries have dealt with the venues after the games. I know after London hosted the games in 2012 its made a lot of effort to reuse the venues. The Olympic park was just outside London accessible by public transport and next to a very big shopping centre, so I think utilisation is pretty good. And the main stadium is now taken over by West Ham (one of the Premier League football clubs) solving one very big problem
