Abstract
To balance the needs and actual or potential facilities, mankind has tried along with time. Water, ground, soil, road is from environmental factors forming a living place while one or more factors may play more important role depending on some situations. The culture is created due to people interactions and is progressing longitudinally and affects human activities. Ignoring the environment makes the debate impossible on cultural and behavioral conditions. Culture creates sites and phenomena around the spaces and places. Architecture is one of the main sites of culture in environment. Natural characteristics in the region of Ghahestan made the Ismailia – in the Islamic middle centuries - to establish defensive buildings due to cultural and religious conditions. The results made them to be in accordance with the political and natural conditions of the time. In spite of some environmental limitations, they provided their need in the environment and caused some sort of cultural and environmental accordance in the region. This study introduces the Kouh Zardan castle of Zirkouh city in South Khorasan. This castle has spent two different residence eras. The castle was used as a defensive place at the first era may be known as Saljooghi. Ilkhani’s were the second residents.The main question of the research is, what role has the natural geography of the area played in the castle of Castle Zardan Mountain architecture? The castle of Zardan Mountain has been built with regard to the environmental conditions of the area and the impact of the environment in the castle architecture space is not only in the use of native materials, but other factors such as climate, altitude, distance and proximity to water resources, geological structure and ... has played a key role in the formation of the castle. This paper is descriptive and analytical and its data has been through library resources and field surveys.

Introduction
The breadth of the land of Iran, along with the diversity of its posterity, has created a situation in which the inhabitant should think in a special area of thought with creativity and sharpness in order to maintain, maintain and maintain their place of residence (Pazoki Tohruidi , 1376: 101). Environmental conditions, especially the climate, soil type, water resources, etc., can play a crucial role in the formation of a civilization (Wylie, 2007: 11). Among other factors that make use of these conditions in the environment, culture is. Culture is the result of an interpretation that humans themselves and their relationships with each other and nature (Abedi Sarvestani and Shah Vali, 1391: 2). If one looks at one of the applications of culture, then architecture as an outlook for human beings is one of the important aspects of culture that is studied in the geographic area as a perspective (Fayaz et al., 2011: 92). In many parts of Iran, there are works of old castles that have been constructed with the administrative and political conditions of their period and connect with their surroundings and create a solid structure. Quhistan is one of the places that has caused a favorable environment for the construction of the Ismaili dome in the Middle Ages due to its mountainousness due to the desert of central and loot, the plain called Afghanistan and the political and religious conditions. Castle Mountain Zadran One example of this type of castles, in South Khorasan province is located in the city Zirkouh the height of the mountain fortress Zadran on it and mastery of the environment, a perfect opportunity to the mountain’s topography around The fort is composed of mountainous and plain. In this article, the geographic conditions of the area and its impact on the architecture of Castle Zardan Mountain are discussed.

Castle Zardan Mountain
Castle Zardan Mountain is located in South Khorasan province, Zirkouh city and Zardan village, and is based on the point (UTM) at latitude and longitude 747004/3707960 with an average elevation of 1,770 meters above sea level. Castle Zardan Mountain is located above a single mountain (between 50 to 90 degrees) and overlooks the surrounding plains. The length of the castle is 100 meters and its width is 80 meters with an area of 8000 square meters and a height of 92 meters from the surrounding environment. The castle is based on a nearly square shape (Nasrabadi, 1391: 111). The architectural features of the castle include the remains of several towers, parts of the fence, the walls of the castle’s interior spaces, water cabinets, and several chamber-covered rooms. Citadel of the castle is located in the highest castle space. Some of the architectural spaces of the fortress are crafted in the rock form, so that rocks from the bed of this space can be used as building materials for the walls. In view of the architectural space of the castle building, it is seen that most of the residential spaces of the castle are opposite to the cold weather of the winter, so as to see some kind of compatibility with the winds of the area in this castle. For the construction of Ismaili castles, in addition to choosing it geographically, in the harsh areas, the villages near the fortress were chosen according to the Shiite religion, especially the Shiite Ismaili, as well as the environmental facilities including the water they had. Castle Zardan Mountain is located in a relatively blue area and today it is rich in agriculture. In the choice of castle, the environment was also considered vegetation, so that if materials such as bricks and pottery or melting metals were used for molding weapons, it was possible to make furnace with regard to vegetation.

Conclusion
Climatic factors have created buildings and spaces that are consistent with the environment, which is in fact the outlook for warm and dry regions, which expresses the complex relationships of man with its rough environment, so that architecture is the most obvious type of landscape (peasant, 1382: 68-67). Among these architectural views, it is possible to construct an Ismaili dome in most parts of Iran, especially in Qehistan. Castle Zardan Mountain is one of the Ismaili castles in Ghahistan, which is built according to the environmental conditions of the area and is related to some kind of architectural complexes of the castle with surrounding environment. Environmental factors were also very influential in the construction of the Castle Zardan Mountain due to cultural and historical factors, while how to form the fortress in order to adapt to natural conditions is more than anything else related to its surroundings. The influence of the environment in the castle architecture was not limited to the use of indigenous materials, but other factors such as climate, elevation, distance and proximity to water resources, geological structure, etc., also played a key role in the formation of the castle. In general, the most important factor is the formation of a water culture, access to water, and whether these water structures can be seen inside or outside the castle. But from other points of view, the castle landscape architecture is surrounded by the surrounding environment around the castle. The communication route is also seen in the perspective of the castle of Mount Zardan and other Isma’ili castles close by. The Castle Zardan Mountain is located on a single high mountain point with a steep pitch towards the surrounding area, for the sake of ease with the surrounding area and connecting with other Ismaili castles in the landscape.

Abstract
The motifs in Iranian art carry the concepts and themes that represent the worldview of human societies; the motifs that embody the seals reflect the legacy in which the context was created. The present study studies and analyzes animal motifs on lattice seals in southeastern Iran; one of the most interesting phenomena of the Bronze Age cultures in Iran is the prevalence of lattice seals in the southeast of Iran. These types of seals are generally made of bronze as well as silver in rare cases, and various alloys made with the missing wax method. The purpose of the present study is to identify their concepts and themes and to identify the factors that were involved in creation of the motifs of this period. It should be noted that these seals are made in the form of squares, circles and triangles and include geometric, plant, human and animal motifs. No substantiated theory has been put forward regarding the importance of substances on metal lattice seals. Obviously, information extracted from specimens used in the lattice seals of the southeast Iran during the Bronze Age can greatly shed lights on many of the ambiguities in this area. From this point on, we attempt to document the various conceptual and content dimensions of the design, based on a descriptive-analytical research method, relying on a library study method and assuming that the design of these designs is based on the surrounding nature and Indicates the importance of animals in the live hood of the people in this area, we discuss and analyze. The findings of the study indicate that these animals depicted on the seals have a significant influence on the lifestyle and status of these animals in the religious and intellectual beliefs that overwhelm in this area..

Introduction
Since the emergence of man on the scene, his attention has been focused on animals. animals have become an integral part of his life. This attention in the Paleolithic times was in the form of paintings on the caves wall, which somehow created a sense of power and superiority over these creatures, and somehow reflected his mastery over hunting. In this way, archaic man, without writing, only made the future known to his imagination and beliefs, instead of just visual arts. However, today’s human beings cannot experience their ancient culture and discover their mystery. Because some of the elements that today seem trivial and are part of human biological practices were once sacred and divine to them. Scientists and anthropologists have different views on the emergence, evolution, transformation, and diversity of the gods. But we can still draw a weak line from this. It may be somewhat plausible that it has a direct relationship with the production system and the environmental characteristics of humans in the emergence and development of gods. From the logic of practical philosophy, man has created gods at the shepherd stage that are different from the gods at the agricultural stage (Darwish, 65: 1355). During the Neolithic period, this dependence was inseparable from the extent to which humans were interested in domesticating animals and using them in their daily life (agriculture and animal husbandry). He also designed and used animal bones on his artifacts, including pottery. And it has benefited from agriculture and commerce. During the Bronze Age, the interest in animals was not only diminished, but also had a special place in the way that the role of animals was performed on reticular seals specific to southeastern Iran. Important questions that are addressed in this study are: What is the role of the applied seals and for what purpose? The purpose of this study is to determine the status and importance of these animals in the life cycle of these populations, and the hypothesis is that the function of animals is essential in the economic and livelihoods of these populations.

Animal Motifs
Thousands of years have passed, and humans have continued to ambush, trap, or hunt for their own livelihoods and for the survival of their generation. The hunter-gatherer thus established a long, intimate, unbroken bond with the animals through hunting, and owed his long life to them. It is not clear to us what kind of animal that human was feeding at that time, or what beliefs, beliefs, and beliefs they had. Our scant information only includes the remains of bones and the kind of tools that come from ancient sites and give a very clear picture of those communities. However, this little information suggests that from a Paleolithic perspective, everything was sacred. “Everything that human beings have used, felt, seen and loved, has become a holiness magazine,” says Mircha Eliade. Therefore, even the animal, which was all human, could not be sacred (Eliad, 32: 1372). The first evidence that we can find in the hunter-gatherer beliefs and ideas is the paintings they left in the dark caves. And. Perhaps these paintings “were a means of human control of the animal and of the animal being called to the hunt. In this way, the man was supposed to first capture the prey in the depths of the cave and to take his carcass out of the cave easily” (Asadian Khorramabadi, 58: 1358). Animals such as eagles, scorpions, cows, goats and fish are found in the lattice of southeastern Iran. It seems that due to the presence of such animals in this region, they have been engraved on the seals.

Conclusion
Thousands of years have passed and humans have been lurking for animals to feed themselves and their offspring, trapping them or hunting them with very simple and basic hand tools. The most important manifestation is the role of animals in their beliefs. Totem and totem worship. According to them, their great soul has become an animal or a bird after death, as a result of which all of them have been created from an animal or a bird. Therefore, this animal or bird was sanctified by them, and in all aspects of their lives, such as religion, magic, ordinary and everyday currents, especially artistic creations, it was manifested and found a significant presence. By examining the animal motifs used on the south-eastern lattice seals, their importance in the life of the people of this period can be achieved. This importance has been so highlighted and valuable that they have illustrated their artifacts. It is also possible to understand the existence of this type of animal in its bed and environment and its functional role in providing livelihood and subsistence economy of the people of this period. Animals whose importance and position are rooted in the thoughts, ideas, beliefs of these people.

Abstract
Tol-e-Zahak site, as the ancient city of Fasa in the historical and Islamic period, is located about 2 km south of the modern city of Fasa in the eastern center of Fars province and was registered as the 15th national monument in 1310 AD. After conducting a archaeological systematic survey of this site in 1397, in addition to identifying the extent of the site (based on the dispersion of surface data) which reaches more than 500 hectares; Chronology and settlement periods of the site, which indicate its habitation from the late fourth millennium BC to the Islamic Middle Ages; It was found. By studying the data obtained from the survey, especially pottery samples, one of the important settlement periods of Tol-e- Zahak area is the settlement related to the Sassanid period. Scattering of cultural materials related to this period (especially pottery) was observed almost all over the site. In this article, the authors intend to examine the historical sources and previous archaeological research in the region in connection with the Sassanid period in the region, the results with the data related to the Sassanid settlement identified from the methodical study of Tol-e- Zahak site, Intertwined (Historical Approach) and to reconstruct the appearance of Fasa city in the Sassanid period as much as possible. Studies show that the Sassanid settlement of Tol-e- Zahak site is undoubtedly a large urban settlement of the type of cities with an irregular shape of the Sassanid period. Due to its strategic location and suitable environmental conditions for agricultural and livestock activities, this city as one of the important commercial and commercial cities throughout the Sassanid rule and even a few centuries after the advent of Islam in Darabgerd province in the east of Persia Has played a role.

Introduction
Fasa is a city in the eastern central of Fars province, despite the environmental conditions suitable especially for agricultural activities and also its special strategy position, which is located between the civilization areas of the east and west of the Iranian plateau on the one hand and the access route to the open waters of the Pars sea, despite the identification of many works and sites from prehistory to late centuries, Islamic archeological knowledge, especially the situation of the region in its historical period is very small Zahak bridge (Tol) is the largest ancient site of the city and one of the most important ancient sites of Fars. Most of the researchers in the area are related to the pre-revolutionary period. Some limited investigations were carried out on each of these sites based on a specific settlement or only included the main mount of the area which gave its name to the entire part. So it’s necessary to carry out a systematic investigation that covers the entire area of the site and all settlement periods. After the systematic investigation of the site that was carried out in 2017C (1397) based on the distribution of cultural materials. 
The surface area of the site was more than 500 hectares it was reached with the chronology of the cultural materials of the period of the residence in the site from the end of the fourth millennium to the middle Islamic century it was estimated continuously without interruption it seems that despite the most Sasanian cities during the Sasani’s period, the city of Fasa has been an important commercial city in the region since and it reached the peak of its expansion and prosperity in the Sasanian and early Islamic period. On the other hand, the historical and geographical sources of the beginning of Islam have a close relationship with Sasanians and called the city a large city with many products and prosperous commerce a city that has all the important structural features like; Kohandej, Baroo, Khandagh Sharrstan, Rabz… .

Data
The largest number of sites identified in the archaeological survey of Fasa which was conducted in 2008 (1388) belongs to the Sasanian period. A total of mounds and artifacts have been identified from this period (image 3). Of these 18 sites, only Sasanian settlements Also 28 sites were identified with the continuity of settlement from the Ashkanian to Sasanian period, 1391(166), the results of archaeological investigation and excavations region in Fasa indicate the importance of the region such a way that all the boundaries of the city witness settlements related to this period include urban and rural settlements, (watch towers), (fire temples), (water structures), (cemeteries), etc.
The main part of this article is derived from the results of the methodical archaeological survey of the site of Tol Zahak, it’s necessary to give a brief explanation of the survey and sampling method chosen for this site. Since the area in question is located between the modern city of Fasa and the two villages of Dastjeh and KheyrAbad, most of its lands has been cultivated and turned into agricultural lands for the villagers on the other hand the urban and rural construction in the northern, southern and eastern parts of the are an don’t allow a more accurate estimate of the area out to the size and extent of the area the selection of small square brought problems. So it was decided the entire area can be gridded into units with dimensions of 100 × 100 meters in the main geographical directions. Sampling to select the sample units in this research is based on one of the pre-defined, scientific methods, which is stratified methodical sampling.

Discussion
General chronology of Tol e Zahak and recognition of the settlement periods as well as identification of each period is based on the pottery chronology obtained from the methodical investigation of this area. According to the existence of prominent Sasanian cities explored near Fasa such as Darabgerd, Ardeshir Khoreh, Fasr AbuNasr, etc. Knowing the Sasanian pottery of this area is not very complicated. They have enough cooking. Pottery with a thick red mud coating and gray pottery with a black coating (image 6) of the common types of Sasanian pottery of the Tol-e-Zahak area which were identified from almost all investigated units. Among the interesting points of Sasania’s pottery of the Tol-e- Zahak is the use of decoration. There is a large undulating log on their outer surface. According to the distribution of Sasanian pottery in the Tol site, the Sasanian settlement covers the entire surface of the site, and it can be called a large urban settlement that is located next to the important cities of Kureh. Darabgerd has been in the eastern center of the Pars state based on the large dispersion of pottery known as Sasanian-Islamic pottery on the entire surface Fasa has passed the transition from the Sasanian period.
In the Islamic period without any change in the urban structure of the area of Tol -e-Zahak, several types of pottery related to this period were found. One of these characteristic types is pottery with an alkaline green glaze with added motifs which was obtained from most of the sampled units of Tol Zahak (image7) other types of Pottery related to this period are pottery with carvings decoration with a wave on the edge and other surface and the pottery is decorated with a grooved log pattern and these samples are almost was found all over the area. Sir Orel Eshtein the first explorer of Tol Zahak describes it as follows: there isn’t a big ancient area in Fasa except Tol Zahak so without doubt this area is the old city of Fasa (eshtein,1936) but this hypothesis was scientifically proven by conducting a systematic investigation. Conditions suitable environment and special strategic location of Fasa due to its location between several royal cities.

Conclusion
Fasa City has different from other important cities of the Fars State in the Sasanian period such as Bishapor, Darabgerd, ArdeshirKhore, and, Estakhr the most important issue is the function of the city and its background and history. The most important cities in Fars in the Sasanian period can be considered royal and religious cities that played a big role as religious centers of the Sasanian period. Without any doubt, the existence of significant governmental and religious structures in cities is undeniable but Fasa can only consider the commercial prosperity of commerce and agriculture as the most important factors of the city’s prosperity in the Sasanian period. It is the commercial center of Fars State and most of the geographers who have visited this city are described in their works. Trade and commerce of Fasa have been praised a lot. Archaeological evidence shows that the Sasanian-Islamic period of Tol Zahak is one of the large and important settlements of the site the Sasanian period and the early Islamic centuries can be concluded this transfer of power from Sasanian to Muslim Arabs which includes the aspect political and religious issues couldn’t have created a disturbance in the prosperity of Fasa.
Their fore description of the large size of the city included commerce and agriculture can imagine the Sasania’s area well. According to the description of the surface, Fasa is estimated to be about 500 hectares and is one of the largest cities. Another issue is related to the historical region in the Sasanian cities. Most of the royal cities in Fars as BiShapor were founded in this period and Darabgerd and Ardeshir Khoreh a little time passed it was used like checkered entities but about the formation of city it is very different issue.
