Visual and Comparative Analysis of Stone Surface Deterioration Observed in Gaziantep Stone Fountains

stone architecture. In this study, a visual analysis method was applied to two historical fountain examples (Köseç Ahmet Ağa and Kumandan Fountains) located in Gaziantep, and stone surface deterioration was examined in physical, chemical, biological, and anthropogenic categories. Within the scope of the study, the deteriorations observed on the facades of both structures were classified and documented with photographs. The findings reveal that the fountains exhibit different levels of deterioration directly related to their usage status and environmental exposure. At the Köseç Ahmet Ağa Fountain, which is actively used, chemical and biological deterioration due to moisture effects are more prominent, while at the Kumandan Fountain, which is no longer in use, physical and anthropogenic effects are more pronounced. The data obtained show that the accurate documentation of deteriorations observed in stone structures is of critical importance for the healthy restoration and sustainable conservation of these structures.
