    For successful restauration of painted walls and painted coloured finishing coats it is necessary to determine the composition of the original colour layers. Identification of pigments used in The ... Cistercian Abbey of Sticna and The Manor of Novo Celje was carried out using optical and scanning electron microscopies. Selected samples of wall paintings were inspected: a) by a combined application of an optical microscope and a low-vacuum scanning electron microscope to determine their colour and structural features and to identify the position of individual pigment grains, b) using energy dispersion spectroscopy to determine the elemental distribution on selected surfaces (mapping analysis) and elemental composition of individual pigments. it was found that the most abundantly used pigments were iron oxide red, cinnabar, green earth, umber, calcium carbonate white, ultramarine, yellow ochre and carbon black. These identifications have allowed us to compare the use of various pigments in selected buildings from different historical periods.
