Through anthropological research over the years, culture has been viewed as a set and an open system of values that has often been under historical change, including the notion of heritage. Furthermore, over the years, culture and heritage have been viewed as a whole and a form, a segment of the cultural identities of peoples and communities. The division of cultural heritage into tangible and intangible heritage included, therefore, the material component, which is visible and tangible, and the immaterial, which is spiritually closely related to beliefs, customs and other broad concepts. Istria has shaped the diversity of its cultural identity and the richness of its cultural heritage, whether tangible or intangible, through its historical periods. Various historical periods have marked Istria as a rich multicultural region, from the beginnings of the settlement of its area and the formation of the first social communities to the present day. Through such diversity, folk customs developed that were present in everyday life. Along with folk customs and social interaction, folk festivals developed, with an important element of social rise and the formation of cultural identity. The process of revitalization and protection and transmission of heritage to generations can sometimes encounter obstacles and be influenced by various internal and external factors. Global changes can therefore have a significant impact on cultural heritage and activities, however with proper adaptation and organization, barriers can be overcome to a greater extent.
