✅ Northwest region of Iran due to climatic conditions and the location of two volcanic mountains Sablan and Sahand; It is one of the prone areas for this type of architecture. In this area, cutable rocks have provided a suitable bed for cutting rocky spaces. 

✅ Finally, the research results showed that in terms of design and pattern, certain types of geometric motifs have been used in the decoration of the historical monuments of Hozdar city and the dominant decorations used in these buildings are made using the pattern and pattern index, and most of the decorations used in these buildings are done by using design and pattern, and color has the least impact among the examined components.

✅ The excavation of this Archaeological site was aimed at elaborating the sequence of Barde Zard settlement as well as cultural interactions of its residents with neighboring areas and identifying the features of the Middle Bronze Age. Excavations of this tepe led to the identification of the Bronze Age settlement and a burial ground. Also, the exploration of the site made visible its cultural attachment with the Urmia Lake Basin and influences from the Khabur culture.

✅ The results of the research show that there are many similarities in the formal, thematic and visual characteristics of the works of the two schools, which indicate the intellectual commonalities of the two schools. The most important difference in Khorasan School is the use of prayer for the owner of the object and the use of human and animal motifs, and in the Cairo school the greater use of the names of kings and the use of geometric motivs and inscriptions.

✅ In total, in this manuscript, six images are related to Żaḥḥāk’s story. This study tries to conclude by comparing the figures and the story which is narrated by Ferdowsi to what extent painters have paid attention to the text for creating images, and if there are differences between the images and text what it is. It seems that in some cases painters have created images which are understandable for the reader of the manuscript.This study is done by using analytical-comparative approach and data collection is based on library sources and observation.

✅ The results of the research show that the hot springs built in the gardens were mostly private or private-public. In some gardens, there is a formal connection between the geometry of the vestibule or the partition space of the pavilion, with the geometry of the Garmaba garden space.By analyzing the positioning of garmabeh in relation to the main axis, sub-axis, koshk and sardar, it can be seen that in all gardens, garmabeh is located in the sub-axis of the garden and in connection with the koshk or the sardar building.

✅ According to the plan, the physical and texture elements in which the tomb has been formed. The result was that the original design of this building was derived from the tomb monuments in Khorasan with a square form in the early to middle centuries of the Islamic era. Also, by comparing the cultural data and the structural elements of the building, its construction date can be attributed to the late Seljuq to Ilkhanid period, it can be attributed to the late Seljuk-early Ilkhanid period.

✅ The results of this research showed that Gambron pottery has been known in Iran since the end of the 11th century of Hijri, and despite its export importance, it has been used to some extent among the people of Iran. Probably, this pottery was produced in centers such as Qom, Nain, Isfahan and Kerman, and its shape and decorations were similar to Safavid examples and some Chinese pottery.

✅ The research has shown that the site location pattern is evident in relation to environmental factors such as elevation and water resources in the formation and cultural interaction of Iron Age habitats. The research area has a suitable climate, low horizontal hills in the plain, direction of agriculture, dependence of settlements on water resources in a linear way shows permanent and seasonal settlements. To give Also, the study of influential environmental factors in the kernel density model determined the highest density of sites in the central and western parts of the region.

✅ In order to identify the physical patterns, the surviving Qajar houses in the historical context of Lahijan as a sample community are studied and while identifying the most effective factors, sustainable guidelines for the design of contemporary structures are introduced with the aim of improving quality dimensions. The results of the study showed that based on the body patterns known in the studied samples, which include four categories of spatial organs (in three scales, macro, medium, and micro), structural, facade, and array, there are identity building approaches and sustainable in the design of today's structures can be pursued in the region under investigation.
