In multi-layered cultural heritage buildings at risk of earthquakes, preserving the authenticity of the heritage building while managing its seismic risk is crucial. However, in such buildings, the sources providing information about the historical process of the building are often fragmented. Due to structural weaknesses and external factors, these buildings suffer damage, leading to interruptions and breaks in their historical continuity. To ensure that a historical building is preserved for the future with all its values intact, it is necessary both to correctly understand the values that have accumulated layer by layer from the past to the present, and to learn from the structural weaknesses and damage that have occurred throughout history. Through the documentation and classification of the data obtained from archival research, this study aims to utilize historical research as a tool for tracing the continuity of structures and revealing earthquake damage mechanisms (specifically, parts exhibiting structural vulnerability). This approach is exemplified by the minaret of the Orhan Gazi Mosque in İzmit and is applicable to cultural heritage sites.
