Abandoned sites / areas / buildings In Ireland

I think there's 1000s of old empty houses and cottages in rural areas and also some apartments which were started but the building stopped in 2007 when the housing market crashed

I know a large 3 storey house it's empty for at least 12 years in dublin 1 I don't know why the owner does not sell it its not in bad nick just empty

I know of a few cool spots but not telling.

I've seen too many spoiled and permanently closed off because people can't fcukin behave themselves.

the ford factory in cork??

The Great Southern hotels in Rosslare and Galway (Corrib), had several a holidays in them as a kid. Abandoned for years.
