The dimension stones used in the construction of the Old City Wall of Cluj-Napoca, Romania are Eocene limestones, which were quarried in close vicinity of Cluj. Different facies types reveal different weathering features. The weathering processes are complex and the weathering features vary markedly depending on the rock types, composition, weather conditions, geographical position, moisture/dry cycles, position in the building, and exposure to pollutants. The internationally accepted non-destructive method of mapping conjunctively with the new method of determining the “damage indices” allow a precise classification and evaluation of the rock types and damages and also an overview on the development of the damages in time.
