2. Inscribes Soltaniyeh (Islamic Republic of Iran) on the World Heritage List on the basis of cultural criteria (ii), (iii) and (iv):
Criterion (ii): The Mausoleum of Oljaytu forms an essential link in the development of the Islamic architecture in central and western Asia, from the classical Seljuk phase into the Timurid period. This is particularly relevant to the double-shell structure and the elaborate use of materials and themes in the decoration.
Criterion (iii): Soltaniyeh as the ancient capital of the Ilkhanid dynasty represents an exceptional testimony to the history of the 13th and 14th centuries.
Criterion (iv): The Mausoleum of Oljaytu represents an outstanding achievement in the development of Persian architecture particularly in the Ilkhanid period, characterized by its innovative engineering structure, spatial proportions, architectural forms and the decorative patterns and techniques.
