Erdődy Castle, located within a large garden in the city of Jastrebarsko, was built at the turn of the 15th and 16th centuries as a medieval castle. For a short time it was owned by the Pethö de Gerse family, and from the 16th to the 20th century it was in possesion of the the famous Erdődy family, which gave the castle its present appearance. Due to its stylistic layering and preserved phases of contruction, the castle has a high architectural, historical, urban and ambient value and has a status of protected cultural property registered on the List of Cultural Goods of the Republic of Croatia. At the end of the 20th century, the castle was left without any purpose due to the start of the the renovation, which was never completed, and has been left to decay ever since. However, as the castle has great importance and significance for the inhabitants of the city of Jastrebarsko, in 2017., the City began to develop the Project of Restoration and Revitalization of the Erdődy Castle in Jastrebarsko with the aim of renovating and adapting the castle for the needs of a new purpose. In the castle, it is planned to place many different facilities and services, both public and economic, which will improve the quality of everyday life of the local citizens and enrich the cultural and tourist offer of the city and its local area. The project was co-financed by the fund of the European Union, which greatly contributes to the faster and more quality restoration and revitalization of the castle. In this master's thesis, Erdődy Castle in Jastrebarsko is presented in the context of profane architecture from the 16th to the 18th centuries in continental Croatia with a detailed review of its valorization and conservation guidlines for its restoration. The paper also provides information about the Project, as well as a detailed description of the planned interventions at the castle, in accordance with the suggested conservation guidlines, and the intended new purpose of the castle.
