Thinking about it, most of Ireland is basically if Detroit was spread really really thin.
We have these things called Ghost Estates from when the economy went bad. They were these houses built out in the country thanks to the lack of space in Dublin. Some of these managed to get completed, while others still have the abandoned tools and rubbish from the builders, while others are simply skeletons of buildings. When the economy fucked itself in half, Ireland was hit really hard because we had been really poor up until what we call the "Celtic Tiger" where we got an influx of money, which spent us on a spiral of drugs and ill-advised plans. The Irish don't really know what it's like being rich. The majority of the projects still being worked on went sour and many of the people working on them fled the country, so the builders left because no-one was paying them. So you have these useless buildings souring the landscape that are completely empty of anyone except crackheads and the occasional wild animal. They are everywhere and I have only seen one near a Tesco get knocked down, which had been there since 2008, I believe. And they occasionally kill kids wandering near, yet they aren't getting knocked down any quicker. Again, this isn't in a cityscape: this is in the middle of idylic countryside.
A poetic way of describing it would be that Detroit was damned by it's own despair, while Ireland was damned by it's own hope. On the optimistic side, it'd make filming a post-apocalyptic film in Ireland really easy.
