Right, obviously they're not going to be in the New World. The question is why those countries, of all the ones in the Old World? There's very little in France, the UK, Norway, Albania, India, Syria, and a heck of a lot of other places with thousands of years of history.
Switzerland and Japan, maybe. What is now Germany was not particularly stable during the Middle Ages. Or the Early Modern era. Or the 20th Century for that matter.
