Plenty of European countries have conflicting city/town/village names as well. If they grow to large they are sometimes specified by adding more locality to their name.
Denmark has three cities names Nykøbing, typically specified as Nykøbing Mors, Nykøbing Sjælland or Nykøbing Falser. Small places are just allowed to conflict as long as they aren't in the same postcode.
Frankfurt am Main and Frankfurt an der Oder in Germany.
In "Frankfurt-Hahn" the "Frankfurt" is still the same Frankfurt you (probably) wanted, you just got a different airport located further out. "Frankfurt an der Oder" is on the other side of Germany on the border with Poland, a ~7h drive away.
So this is more like you going to NY and landing at Newark when you expected JFK where Frankfurt an der Oder would be like ending up in New York, Iowa.
Indeed, Italy has a ton of cities called something like "old town", "new inn" or "castle", for obvious reasons.
