This graduate thesis covers the tangible and intangible cultural heritage of the Republic of Croatia. At the beginning of the work, the theoretical part of the very concept of heritage is mostly explained through legislation, and then its division. Thanks to its rich history, Croatia, given its territorial size, has an extremely large number of cultural assets, of which as many as 25 are included in the UNESCO World Heritage List. The second chapter presents the cultural heritage of the city of Split and describes in more detail the most prominent examples of tangible (movable, immovable) and intangible Split heritage. Cultural heritage is a public good of humanity that belongs to every individual and as such must be protected and preserved. The third chapter defines the legal regulations of the Law on the Protection and Preservation of Cultural Heritage. Through the highlighted examples in the fourth chapter, the engagement of professional institutions for the purpose of protecting the cultural heritage of the city of Split is emphasized. The last chapter of the work presents the results of a survey questionnaire aimed at examining the knowledge of the population of the Republic of Croatia about tangible and intangible cultural heritage, and knowledge of the basic concepts of the same.
