Traditional cultural heritage is a very important attribute of national identity. Folk customs and oral literary forms are its essential components. This thesis illustrates the existing customs and oral literary forms in Imotska krajina. Descriptions and clariffications of certain customs and forms of oral literature that informants are speaking of are added to field recorded tellings of elder residents. Christmas and advent, lenten and Eastern customs as well as customs by which we worship certain saints, everyday customs and songs, traditions, riddles and proverbs preserved in national memory are recorded. Folk customs, which are one of the main subjects of etnological researches, are symbiosis of religious and secular motive and they are always in functional correlation with time and surrounding in which they are performed. Just like everything else in human life, stories and customs are changing and carrying a mark of historical processes. Social, economical, political and religious occasions have an effect on customs, transforming them and changing their meaning. That way, customs from Imotska krajina region are substantially changed and "modernized" in the last few decades, and a lot of them are likely to be forgotten. It is of utmost importance to preserve these components of traditional cultural heritage so that we wouldn't lose this very important part of our national identity.
