The guardian-Observor's article is about the decline of Detroit, a great city. The pictures are indeed outstanding. It's heartbreaking to see a giant hall, be it church, railway station or theater, no longer needed. Like Cathedrals of old, all across Europe, unless the structures are used for tourism too, the supporting populations, having shrunk, can no longer pay for the upkeep. There is none more fabulous, perhaps, than Notre Dame in Pairs. Yes, at times the congregants pack the place, but at others times it's almost empty.
Theaters, churches, great halls all require a regular flow of interested people for whom the buildings are a necessary part of their lives.
In Detroit, with the collapse of a great part of the auto Industry there, (blame the Unions, blame Detroit companies, blame imports), folk cannot pay their mortgages and but groceries, never mind travel, go to theater or drive to their favorite church.
Still, with these buildings still standing, a great inventory of new possibilities is created. New projects can now rehabilitate and repurpose the neglected buildings and kick start the new ideas that can work in the Detroit that will re-emerge. Some uses will shock us but some will be really adventurous and help the community recover.
Unless the population moves away, the buildings will be exploited for new purposes or else will vanish.
