Apparently a bloke decided to extend his retirement income by buying a property in Portugal. It was a nice place, except for a really ugly barn blocking the view. The doors were welded shut. The previous owner died without issue and the place was being sold by the government to pay back taxes. Anyway, he could afford it and thought he would just knock down the ugly barn.
Here is a pictorial record of what he found inside:

You can never tell with the net, but it looks pretty real to me.
