In this study material of wall paintings were analyzed to determine the structure of plasters, mortars, and pigments of Side wall painting samples. Archaeometrical methods were used to investigate mineralogical and chemical compositions and raw material characterization. Binder-aggregate ratio and particle size distribution analysis, gravimetric analysis, petrographical thin section optical microscopy analysis, Raman Spectrometry, XRD, PED-XRF, SEM-EDX techniques and methods were used to examine the samples. SEM-EDX analysis and Micro-XRF analysis indicate parallel results especially for iron (Fe) content of the samples. Iron (Fe) is the main element that plays a role in the formation of pink and red colors. As a result of thin section optical microscope analysis, wall painting samples could be divided into three different groups. The main components in arriccio plaster layers are aggregates and binders. As a result of aggregate and binder analysis, arricio layer samples contain 63.32% percentage of aggregate regarding with average values. The aggregate structure of the samples is composed of very large, marine origin, rounded aggregates.
