Croatia is extremely rich in folk customs, songs, costumes and instruments. Each province has its own cultural wealth. Cultural heritage is the foundation of the nation and it is important that it is being passed on from generation to generation because that is the way to keep it alive. Students need to learn about cultural heritage from an early age, so they would know what makes their province special and they would be able to pass that knowledge onto their children. That way Croatian culture stays in the nation forever. The goal of this paper was to find out, using a questioner, how covered cultural heritage is in a classroom, especially in Music, how well do children know Croatian cultural heritage, do they know some folklore dance ansambles and their work, do they like cultural heritage.
