The Barakoni Cathedral, built in 1753 in the Racha region of Georgia, stands as a distinguished monument of Georgian ecclesiastical architecture. Recent observations have identified chemical and biological deterioration on its walls, including surface greening and cracking. This paper analyzes how restoration interventions, particularly, the replacement of the original roofing with copper and ongoing climate change (e.g., increased humidity, rain, and thermal stress) contribute to the degradation of the building stone. Emphasis is placed on the material’s mineralogical composition and associated chemical weathering mechanisms to offer science-based recommendations for conservation.
