Glad you pointed it out, there was something that didn't quite add up there. Yes it freezes in europe, those pipes would get destroyed if they were on the outside.
It's probably easier to replace pipes in an older European house anyway; less insulation / less layered walls, less things embedded in concrete, sometimes even wood beam floors. I lived in a >100 year old house that was renovated at some point, newer pipes and electricity was put up against the walls, then a layer of drywall was applied everywhere to make things look tidy.
