Murals are the main, media of human culture and civilization and the place and its long history in Iranian art is clear. There are specific forms of mural paintings in some Iranian architecture that are different from other usual wall paintings in materials, methods as well as implementation techniques. Unfortunately, these mural paintings are not studied certainly until now. Therefore, further investigation is needed due to the importance of this issue. Regarding to importance of necessity of art understanding before conservation, it is obvious that common conservation procedures on these relics (without appropriate understanding) have an inappropriate results on authenticity and integrity of the relics. Unfortunately, there is not adequate research about technology and conservation of these relics and related fields.  Historical points, manufacturing and used materials, effects of technological problems, as introduction to conservation plan were main questions. The aim of this research is the identification of history of development, and used materials and techniques in these historic paintings by field and literature investigations. Technological understanding of this kind of murals during the time by application of literature review and data explanation. Due to low information in Persian, European Marouflaged Mural has been studied more than Iranian relics. The research subject and case studies are studied in a qualitative and descriptive research method and the subject is considered with ten historical and theoretical aspects. These paintings are executed on the layer of cloth (canvas) and then installed on the wall that is known as a part of the architecture arrays. This research at the first library study is conducted and then according to the results, the field studies are carried out and finally, the data are analyzed. Knowing the number of Marouflage according to literature review, the identification of constituent layers of Marouflage according to field studies, and Understanding the differences between a common wall Paintings and Marouflaged Mural in Iran, are the results of this paper. In this paper, the process of formation of this type of wall painting in Iran was studied and present examples of this method in Iranian architecture are introduced and explained. some of the architectural interior surfaces are decorated by the textile painting by  Marouflaged in Ilkhanid, Safavid and Quajar period; funerary monuments with polygonal plan have the most decorative surfaces such as Soltanieh Dome, Sheykh Safi mausoleum, Maryam church, Golestan palace and etc. According to studies, there was technical change in manufacturing process of large wall paintings and ceiling paintings at Renaissance period. It resulted to production of new kind of murals which known as Marouflaged Mural. The research obtained appropriate results about production, manufacturing, historical samples and effect of technological problems on conservation of Marouflaged Mural.
