Sažetak
The chronology of conservation of Orlando’s Column dates back to 1825. This paper reconstructs the repairs carried out on the monument, and provides a detailed overview of conservation and restoration between 2018 and the present. It should be mentioned that lateral vertical cracks were noticed on Orlando’s Column in 2007 after it had gone through a complete restoration project. The aforementioned damage, the fact that the Late Gothic monument had recently been restored, and that it is an important symbol of the city of Dubrovnik, garnered a lot of public interest and required a precise diagnosis of the problem. In 2018, protective scaffolding was placed around the Column and the Croatian Conservation Institute began an extensive research project. The research included an inspection, detailed recording of the object, and analysis of the existing archival documentation, which provided insight into the source of the damage. Research continued between 2019 and 2022. At that time, a structural monitoring system was designed and placed in situ to further study the cracks. Structural monitoring was accompanied by additional extensive technical research: measuring dynamic parameters, performing structural and ultrasonic measuring of the stone, and trial conservation and restoration. Research results helped determine the cause of the cracks, and precise guidelines were adopted for further conservation and restoration to be carried out in 2023 and 2024. The work entailed loosening the force of the central mandrel of Orlando’s Column, which unfortunately did not reduce the damage’s progression. On the basis of the research conducted, the author offers new recommendations and suggestions for further work that needs to be carried out on the monument that would ensure complete in situ conservation and restoration.
