Europe was heavily damaged during World War II. There are countries, especially in southern Europe, where as a tourist you go into these ancient city centres, but most of the housing stock in a place like Spain or Italy is actually quite new. I don't think the age is actually all that different. As a tourist, of course, you don't want to visit some 1960s suburb of Madrid. You want to visit the beautiful little city centre. Most Europeans are not living in 300-year-old buildings. They're living in much newer ones.
