The mutual experience of European architecture during the transmission phase of Romanesque (around 11th and 12th centuries) to Gothic style simultaneous with Mongol invasions and political revolution from Seljuk empire to Ilkhanids have been assumed as a turning point through Iranian and European architecture. Thus, clarifying its mutual properties is one of the controversial discussion topics related to architecture history. This project aimed to investigate the effective factors influencing the coincidence of deformation of proportions during Ilkhanid and Gothic eras. It also analyzes the existence of different archetypes according to the hypothetical-inductive methods to answer the question "what was the role of religion in the deformation of architectural proportions during Ilkhanids and Mongols´ eras?". According to the results about Ilkanid and Gothic architecture, theory, and practice have been intermingled in a way that no border can be defined between religious principals and the mentality of placement in high-rise structures for linking to God and creating high-rise structure for guarantying such a link. In addition, according to most of scholars, the increasing dimensions of the structures in two different geographical regions of Iran and Europe resulted from political tensions and benchmarking reciprocal achievements. Therefore, it seems that the rising movement of architecture in two different architectural styles of Ilkanid and Gothic eras have passed two distinguished courses and two factors of "the highest" and "the brightest" distinguish the architectural mentality of two different regions.
