Elucidating the relationship between restoration periods and humidity-induced damage in historic buildings: a case study of the Yeni Cuma Mosque

Purpose This study investigates the correlation between restoration periods and humidity-induced damage in historic buildings, with a focus on the Yeni Cuma Mosque. The mosque's unique architectural features and historical significance make it an ideal case study for understanding the complex relationships between structural changes and humidity-related problems. By analyzing the mosque's restitution periods, this research aims to identify the causes of moisture-induced damage and provide recommendations for conservation practices. Design/methodology/approach The study proposes a novel conservation strategy centered around understanding the relationship between restoration periods and humidity-related problems, focusing on the preservation of original materials and structures rather than introducing new materials or technologies. Findings The analysis reveals that the mosque's deterioration is primarily attributed to capillary water rise and biological formations on external walls, as well as inadequate drainage systems. The study highlights the importance of understanding the underlying causes of humidity-induced damage in historic buildings, which are often linked to structural changes during restitution periods. Specifically, the findings suggest that the mosque's second-period restoration work, which included the addition of roof surfaces, contributed to the exacerbation of biological formations on external walls. Originality/value The findings of this research have significant implications for the conservation of historic buildings, highlighting the importance of considering the impact of structural changes during restitution periods on humidity-induced damage. By adopting a holistic approach that integrates historical, technical and environmental factors, conservators can develop effective strategies for preserving these cultural heritage sites while maintaining their authenticity and integrity.
