I can't quite find any towns in the region with a large enough Croatian-speaking minority to list it on the map (Tivat has ~8%) but if you have any others I will update it!
Hello, Croatian is spoken in towns such as Donja Lastva, Lepetani, Bogdašići and Strp, which are located near Tivat and Kotor. By the way, great quiz, I nominated it!
