@alexink People used to live on the ones in photos 4/5/6 up until the 50’s. Then it was granted UNESCO Heritage status, and they cannot do it now.
@maique Oh, that's a shame. They should still be allowed to live in them, after all, that's what they were made for.
@alexink We made fun of that, because they’re allowed to have coffee shops! Not allowed to live there, but ok to do business. Go figure!
