Oral native heritage is a characteristic of all people in the world and It is also very important for preserving the tradition and customs of one nation or community. It is usually passed down from generation to generation, created in places where there was no, or few, literate community members. The authors of the oral native heritage, the persons who created it, were not necessarily the ones who transmitted it, that was the role of the performers. This thesis explores the oral native heritage of the place of Cere, which is in central, rural part of Istria. The paper briefly deals with the history of Istria, the customs of speech and ways of preserving the oral native heritage in the researched area. It also explores in more detailed way oral customs of Cere and examples of oral native heritage. Examples of the oral native heritage of Cere are taken from the literature and from the interviews conducted by the author with the local community members of Cere. Discovered examples are arranged in theoretical categories: lyrical and epic poetry, dramatic creation, oral native rhetoric, proverbs, riddles and short stories. Examples were discovered in every category except for the epic poetry for which no examples were found. Notable fact is that many examples of prayers were found. Prayers, however, are a category in the theory of oral literature. There is no records for discovered examples since those have been passed down from generation to generation by word of mouth.
