In this research, a rapid seismic assessment of the I Gymnasium in Sarajevo (Bosnia and Herzegovina) was conducted. The structural information was obtained from original designs, visual inspection, which was supported by the usage of a drone, and infrared thermography. The vulnerability of the structure was assessed by implementing the Vulnerability Index Method (VIM). Once the mean damage grades were obtained for various seismic intensities (EMS 98 scale applied) vulnerability curve was constructed, enabling the quantification of risk for various seismic scenarios. The structure would experience no to minor damage if exposed to weaker earthquakes (IV–V). The most interesting intensities for Sarajevo are VII and VIII, indicating moderate damage. For earthquakes of higher intensities (X–XII), there is a significant increase in heavy and severe damage, leading to the complete collapse in the case of XII intensity level. The paper further discussed the effects that have a direct impact on the degradation of masonry material, leading to a reduction of its resilience. An aspect of inadequate strengthening is emphasized, together with the importance of regular maintenance for prolonging the life of these types of structures.
