The castles and manor houses of Slavonija and Baranja began to be built at the turn of the 17th and 18th centuries, that is, after the defeat of the Turks near Vienna in 1683 and after the liberation of Slavonija and the expulsion of the Turks south of the Sava river. The 20th century has left the biggest mark on our older monumental architectural heritage. Unfortunately, these impacts were mainly negative and destructive, and relatively few old building were restored. Tourism valorization is possible today in the castles and manor houses of Slavonija and Baranja, which have been preserved and restored. Since the beginning of the 21st century, the restoration projects of castles and manor houses have increased dramatically. In the most of the castles restored today, the original interior has been changed and has a different function (most often it is used as a museum) such as: the Eltz castle in Vukovar, the Odescakchi castle in Ilok, the Pejačević castle in Našice, which in addition to tourist visitations also has a library and a reading room and the eponymous Pejačević castle in Virovitica, which was renovated for the needs of the city museum. The mentioned castles are highlighted in this final paper. In this paper, turistic valorization is directed towards the recognition and the analysis of restoration projects and revitalization of unrenovated buildings as cultural goods,their inclusion in tourist purposes in the form of repurposing space for the needs of museums, tourist information centers, presentation halls, exhibition spaces and other tourist facilities.
