> Munchen - Munich, Monaco

As a french, this one caught me off guard. Didn't help that you used the french word as second alternative on first ones, but til that in italian Munich is called "Monaco di Baviera". Now I wonder what's in common between those two cities..

This is mostly but not entirely coincidental. The name München is derived from the word for monk, which would be "monaco" in Italian. Both "monaco" (monk) and "Monaco" (city) ultimately descend from μόνος (Greek for "solitary").
