Abstract
One of the main types of rock monuments is hand-carved ritual-religious spaces. These handmade spaces have long been considered, sanctified and respected by religious social groups who were committed to religious practices. From this perspective, it can be stated that Maragheh region has been one of the most important, rich and long-lasting centers of ritual-religious architecture in the history and culture of Iran. In an era, in which ritual manmade spaces have lost their influence in many areas of ritual prosperity and sacred power, some ritual-religious manmade spaces in Maragheh still have an active and prominent presence. Accordingly, the present study, while identifying, introducing and explaining the special features of the ritual-religious hand-carved spaces of this region, has also addressed the formation factor of these ritual spaces; and seeks to answer the following question: to how many types are the ritual-religious hand-carved spaces in Maragheh divided? Therefore, along with the field study method applied for recording and explaining the current situation, library studies were also used to identify the factors influencing the formation of ritual-religious architecture in Maragheh. The results of the studies indicate that 8 religious-religious rock monuments have been identified in the county of Maragheh. Typologically, the above-mentioned rock architecture can be classified into surface and subsurface forms. Also, in terms of typology and classification of the application nature, these works have had different uses, such as: a) mosques, b) monasteries, c) churches, d) Buddhist temples, e) open temples, f) crypts, and h) rock graves. Many of these sites are now ruined, however, some spaces have retained their sacred position and are being used with some modifications.

Introduction
The county of Maragheh is located in the northwestern part of Iran in the province of East Azerbaijan, on the southern slopes of Sahand Mountain. According to national divisions, the county of Maragheh has two districts (central and Sarajo) and six villages. The county of Maragheh consists of two separate parts: the northern areas of the county that are mountainous and the central and southern areas which consist of plains and flatlands (Khamachi, 1991: 459). Sahand mountainous mass is one of the most important topographic features of the county, and the southern slopes of this mountain form the configuration of the main part of the county. The general slope of the land in this county is from north to south and the three rivers of Leylan Chay, Mordagh Chay, and Sufi Chay are the important rivers that supply the water needed by the region (Morvarid, 1981: 12).
In the county of Maragheh, numerous historical monuments are remained from different periods, some of which are used as ritual-religious hand-carved spaces. Ritual-religious hand-carved spaces in Maragheh, in particular and other areas in general, have long been considered, sanctified and respected by social groups, according to the existing evidence; Therefore, in this paper, it has been attempted to explain the formation factor, analyze the use nature of spaces and the period in which they have been applied using the a spatial archeological approach and archeological surveys after introducing the ritual hand-carved spaces. The current research has been conducted in order to answer this fundamental question: to how many types are the ritual-religious hand-carved spaces in Maragheh divided? Moreover, the purpose of this study is to investigate and analyze the typology of the mentioned hand-carved spaces. 
Methods: The present study has been conducted using a descriptive-analytical method and data collection has been performed using library methods and field visits from a large number of hand-carved spaces in different parts of the county of Maragheh.
The Significance and Necessity of Research: The rocky and cave nature of worship places and the study limitations of the ritual-religious hand-carved spaces in Iran have caused any religious hand-carved spaces to be associated with Mithraism; however, little evidence of Mithraism has been identified in these sacred spaces. Accordingly, by conducting studies on the ritual-religious hand-carved architecture in the county of Maragheh, it is possible to provide a comprehensive classification of this type of architecture and determine the general appearance and nature of their spaces in this region. 
Research Question and Hypotheses: The current research has been conducted in order to answer this fundamental question: to how many types are the ritual-religious hand-carved spaces in the county of Maragheh divided? One of the hypotheses that can be proposed in the present study is that the ritual-religious spaces of Maragheh have been formed in two periods: the first period is related to the pre-Islamic period, which was influenced by the Urartian culture. The second period is related to the Islamic period. In the Islamic period, the greatest influence in shaping these spaces has been the influence of beliefs from eastern cultures, especially Buddhists and Christians.

Conclusion 
Hand-carved architecture is a special type of architecture that has been created by humans in order to adapt themselves to their environment. In the extensive territory of Iran, due to climatic, ritual and cultural diversity, remnants of this type of architecture can be seen in its different regions. One of the important reasons for the tendency of human beings in different schools towards the rock architecture was the ritual and religious structure of the society, which required turning to rocks and mountains. In the meantime, the ritual-religious hand-carved spaces of the county of Maragheh have been a manifestation of the spiritual life and cultural knowledge of the residents of this region. These spaces have a special place in the whole beliefs of the residents of the region; this has made the decorative elements, architecture and special location of these spaces to be different from other rock works. Following what has been discussed in the text of the paper, the results of library and field studies of hand-carved spaces have demonstrated the influence of ritual and religious structures of Maragheh society in the formation of some of these spaces. Due to the special geographical location of Maragheh region throughout history, the region has witnessed different ethnic groups and special religious beliefs. According to this view, the ritual-religious spaces of the region in the pre-Islamic ages have been created in the form of hand-carved burial spaces (crypts); and in the Islamic period, these spaces have been mostly carved into rock contexts in the form of hand-carved worship temples. 
In the mid-Islamic eras, especially during the Ilkhanid period, Maragheh was the center of various beliefs and this factor has formed the basis for the formation of ritual-religious spaces of Buddhist, Christian and Islamic followers. From this perspective, the county of Maragheh, especially on the banks of Sufi-Chay River, is one of the lively, active, and rich centers of tradition and ritual hand-carved heritage. Accordingly, most of the investigated worship spaces are concrete, objective and real manifestations of the cultural-religious continuity and spiritual life of the people of this region from the Ilkhanid period, and even today some of these places have retained their sacred and ritual status.
 

Abstract
Due to the climatic conditions and cutable stones, the cultural landscape of Sablan Mountain is one of the main foci of the formation of Troglodytic Architecture spaces in the northwest region of Iran. In this region, various Troglodytic Architecture spaces have been carved in different cultural periods, one of the most well-known of which is the Troglodytic Architecture collection of Abazar Nair. This collection, in the previous studies of some researchers, generally belongs to the Parthian era with the use of “mehrabah”; or the Islamic era with the use of “Buddhist temples-tombs”. However, the cultural data in this collection rejects the Mehri and Buddhist monastery hypothesis with sufficient and archaeological evidence. This research is fundamental in terms of qualitative objective and it was conducted with descriptive-analytical method, comparative studies and data collection with the help of field studies and documents-library resources and seeks to answer the following two basic questions: 1- Based on the remaining surface data. Mande, the chronology of Troglodytic Architecture Abazar space belongs to which cultural period(s)? 2- What were the functions of Troglodytic Architecture spaces (number 7) of Abazar Nair collection? The results show that the Troglodytic Architecture space in question, like other spaces in this area, had a livelihood function in the Islamic era. Other results of the research determined that the set of enclosed spaces of Abazar is generally influenced by the climatic conditions of the region and is comparable to other cut rock villages in the Sablan and Sahand mountains. The recent archaeological activity of this collection can be useful and open the way in understanding the functional nature and chronology of other cut rock spaces on the slopes of Sablan Mountain.

Introduction
Abazar area of Nair city is the first Troglodytic Architecture area in Ardabil province that has been noticed by researchers. However, the remaining cultural materials in this area have received less attention from researchers and the most focus has been on the rocky texture of the spaces (Mohammadi-Far and Hemti-Azandariani, 2015; Azad, 2015 and 2016). This factor has caused the chronology and function of this area not to be determined precisely, and one of the empty spaces of this complex (space no. 7), regardless of the architectural elements and cultural materials left in it, is known as Mehri temple belonging to the Parthian era (Shekari). niri, 2019) and Mughal-Temple (Moradi & Omrani, 2020) of the Islamic era. This is while the main differences between the usage and chronology presented for this collection in general and the space of Troglodytic Architecture No. 7 in particular are seen, on the basis of the need to review the chronology and usage presented for this Troglodytic Architecture collection. There is especially space number 7). By examining the surface of the site and studying its cultural findings, while reviewing its chronology and function, referring to the data of the site, the authors are looking for answers to the following questions: 1- Based on the remaining surface findings, what cultural period(s) does the chronology of Troglodytic Architecture Abazar spaces belong to? 2- Handy spaces (number 7). What functions did the Abazar collection have? Carrying out this research will be an important step in the architectural studies of Troglodytic Architecture in the Sablan Mountain range, so that in future studies, along with the careful examination of the sites and the study of the remaining cultural materials, the chronology and explanation of the function of the Troglodytic Architecture spaces of this area can be achieved.

Discussion
Based on the study of the authors, it was found that the Abazar area consisted of several subsurface manmade spaces (10 units) and surface manmade spaces. These spaces were closely related to each other and all of them formed the fabric of Abazar village. Over time, the man-made spaces on the surface were completely destroyed, and today the remains of the foundations and debris of these structures remain on the surface of the area. The texture of the villages in the mountainous areas of North-West Iran has a similar architectural structure. So that in the analysis of this area, what was obtained is that Abazar area in terms of location pattern (access to water sources, location on the mountainside, proximity to pastures), structure and architectural elements and plan of spaces are similar to many others. It is one of the villages on the slopes of Sablan and Sahand mountains.  These villages were formed in a hand-made way near the water sources and the slopes of the hills. Due to the cold seasons of the year, one of the common patterns in the villages of the Sardsir districts of Azerbaijan region is to have small underground spaces where the families lived next to their cattle during certain days of the year. Such a pattern of settlement has been in place until recent years in the village of Kandavan (Razani et al., 2015), Khatb Maragheh (Starnjad et al., 2016), Ganzeq Sarein (Khanali, 2017), Yai Shahri of Maragheh, Sur Bonab. In these villages, the living spaces are located under the surface man-made spaces. Due to their living use, the subsurface spaces generally lacked complex and special architectural and artistic elements common in ritual-memorial spaces (elements such as inscriptions, altars, artistic motifs). And it only has a long manger, niche and spaces for providing light. Such elements can also be seen in the spaces of Troglodytic Architecture Abazar, therefore Troglodytic Architecture No. 7 cannot be considered separate from other spaces from the point of view of architecture and even the nature of the function. The generality of this space is exactly the same as the other spaces of this collection.

Conclusion
What was discussed in the text of the article, the environment of Abazar, like the fabric of the villages in the mountainous regions of Azerbaijan, Iran, consists of hand-made spaces. Handicapped spaces are carved under the man-made spaces, and in terms of architectural structure, plan and practical elements, many similarities between these villages can be observed. The accuracy of the cultural materials and architectural elements remaining in the hand-built spaces of this collection showed that the spaces have many relative similarities to each other and have followed a single pattern. Based on this, a touch space (space number 7) cannot be considered as a space that is excluded from other spaces. All the architectural elements such as the manger, niche, skylight, porch and the way to access the spaces show that these spaces in general and the architectural space number 7 in particular are designed and carved according to human living, based on that. Due to the lack of decorative and practical elements specific to ritual-memorial spaces (such as inscriptions, artistic motifs, columns, luxurious carving style of spaces, etc.), this complex (space number 7) cannot be considered as a space related to He considered the shrine (mehrabah). On the other hand, the nature of the prayer spaces and Buddhist tombs was also very different from this complex, therefore this complex does not have the characteristics of Mehri and Buddhist temples. The chronology of the site was based on the cultural findings left on the surface of the site. Based on these data, evidences from the historical period (especially Parthian) were not identified. These data show the most important settlement period of the site, which coincides with the Middle Ages of Islam. During this period, a cemetery with prominent tombstones was formed in the vicinity of the village. In general, the comparative study of the texture of this complex with the similar areas of Sablan and Sahand mountain slopes shows many similarities between them. Due to the cold climate of the region and to protect their lives and property, the villages of these areas used to create residential spaces in two ways: hand-made - hand-made.
