Plaster design is one of the elements and techniques in the interior design of the buildings which used during Parthian period in Iranian architecture ever since the Ashkanian dynasty era. The Plaster decorations of the Islamic period were formed based on the history of pre-Islamic Plaster art in Iran, and its development evolved during the period of the Ilkhanis era until the Safavid period followed the same pattern and then it declined under the influence of the European art of Plaster decorations. The European influence on Plaster decorations were increased in the era of Qajar and separating it from the Traditional Plaster Design.
