The concession and concession approval on immovable cultural property is the central theme of this work, therefore, normative aspect of the concept and division of the properties of which immovable cultural properties as assets of particular interest to Croatia are part is primarily elaborated in the following sections. Then there is an emphasis on normative regulation of relations in immovable cultural property related to the realization of a private use on them under the rules of administration bodies and why these relations belong to the sphere of public law, and at the end, examples of private use of cultural monuments from practice and experience in finding them will be presented. When we talk about the private use of immovable cultural heritage we think on two legally regulated forms that may occur, those are concessions and concession approvals on immovable cultural property. Common determinant of these forms primarily refers to the satisfaction of the public interest by motivating private investors financialy and materialy, while they differ in number of elements that are presented in much detail in the following sections. Although different, both forms are realized only after the contract was signed between the regulatory authority, as a provider of private use to the immovable cultural property, and economic agent. That giving cultural and historical monuments in private use is a relatively new legal form in our country witnesses the fact that the normative regulation in this area is relatively new and because of that no concrete implementation is not yet under way.
