Few years ago I did a little research on places that have a street named by my hometown - Šibenik.
Although some places are missing on the map (Osijek for example), it is noticeable that many of them are in norther Italy (Via Sebenico). It is also interesting how it is spelled in Serbian (Šibenička) or Slovenian (Šibeniška).
Here are Google Earth screenshots from Rome and Milan
