Abstract
The customs buildings complex at the Persian Gulf in Bushehr Province was built at the end of the Qajar era and the beginning of the Pahlavi era. These buildings are very similar. All these buildings are architecturally built in the same way. All these buildings have two floors and match each other. The architecture of these buildings is derived from the architectural style of the second half of the 18th century and 19th century of the West. This style entered Iran’s architecture as a symbol of modernity and strongly influenced Iranian architecture. It has to be mentioned that this influence was much greater in the last years of the Qajar era compared to its first years. By using the historical research method and library studies, it is tried to collect the necessary data about the research subject and obtain adequate understanding of the customs and telegraph offices in Bushehr Province. 
Keywords: Telegraph Offices, Customs, Bushehr Province, Qajar Era.

Introduction
Bushehr was considered one of the important commercial and cultural centers since ancient times, which would connect the Elamites with the Mesopotamia on one hand and the Melos in present-day India with Oman and the Mesopotamia on the other hand, and this is emphasized in linguistic sources apart from archaeological data. (Hesari et al., 2011; 247) There are some ruins of an Elamite port that are found in a place called Reyshahr, near Bushehr, where an inscription of Šutruk-Nahhunte was discovered and read. This city is probably Liyan Elamite, and it seems that until the 15th century BC, it was under the control of the Elamites and it was a city dependent on Anshan, rather than Khuzestan. Even its name has an Elamite root, and the word NIM is placed in front of the name of this city. Based on the texts of Ur III, Steinkeller has dated Liyan to Bushehr of the late 3rd and 2nd millennium BC and has suggested that Anshan had a direct route to Mesopotamia through this port (Steinkeller, 1982: 252). The new history of trades in Bushehr began with the kingdom of Nader Shah Afshar, which has played a special role in the last two centuries of Iran. By the order of Nader Shah, the main boundary of Bushehr was built by Sheykh Naser Abu Mehiri. (Hamidi, 2010: 50), but the overall structure of Bushehr today was formed in the Qajar era (Ranjabr et al., 2010: 24). In the 18th century, Bushehr was considered as the most important commercial port of Iran in open waters. (Dashti, 2001: 117). The presence of customs in Bushehr Province during the Qajar era caused most of the major countries of the world, including England, Russia, Germany, France, etc., to have a political representative office in this city. This city became the southern gate of Iran for the exchange of political ideas and cultural relations. During the Qajar era, the English telegraph line extended from London to India. This line in Bushehr Province extended to Fars Province, and the line was transmitted from different countries, including Iran, either on land or sea cables. 

Research Introduction 
The main objective of this research is to study the reason for the exitance of customs in Bushehr and the telegraph houses and studying their architecture. The research question is: why are there several customs and telegraph houses in Bushehr? And what are their architectural characteristics? 

Bushehr Custom Building 
The first modern custom building of Bushehr Province, known as Chehar Borj (Four-Tower) is in Bushehr City. This custom was built and established during Naser al-Din Shah Qajar era, by Mo’in-O-Tojjar-e Bushehri at his expense with the plans of the Belgians. This mansion was known as Four-Tower at the time of its building and it was the center of the governance of Persian Gulf ports and islands during the Qajar era. Whenever the governer of Bushehr would come to Bushehr City for the governance of the city from Tehran or Shiraz, they would settle in this place. This building was designed by Joseph Naus, known as Belgian Monsieur Naus. (Fig. 1-8)

Bulkheyr Custom

There are three rooms on each floor and all three rooms are connected to each other. There is a small room on the north side which might have been a pantry. There are stairwells on the northern and southern sides of the building. (Fig. 15-19)
Kangan Custom 
This building has two stories and both stories are similar and they both match each other. The balcony with its beautiful round columns has led to prominence of the building. There has been a stair well in the south part of the building that would connect the second floor to the roof. There is an office, a lobby and a kitchen on each floor. There are squares on the top of each door that were used for lighting. (Fig. 20)

Mohammad ‘Ameri Custom
The unique feature of this building is its shape and design, which was built uniformly on the entire coast of the Persian Gulf. This building is one of the buildings of the Qajar customs whose remains are left, and it was used in the early Pahlavi era. (Fig. 21) 

Lavar-e Saheli Custom 
This building is built in two floors and has an entrance that opens to the west. The two floors are built in the same shape and match each other. There has been a staircase in the south of the building that connected the upper floor and the roof. (Fig. 22) 

Bushehr Telegraph Office 
The telegraph office was initially in Jabri neighborhood and then it is moved to Haft Bangleh in Bahmani neighborhood. The marine transmission cable line extended from Haft Bangle to Karachi in India. The last telegraph and post office in that time was located in Kuti neighborhood near British Consulate behind Shahdokht school, that is ruined now. During Naser al-Din Shah era, telegraph offices were only established by the British and they were managed by British presidents and Iranian employees. 

Conclusion 
Undeniably, architecture changes during any era according to the lifestyle of people in any country. From the middle of the Qajar era, with the change of intellectual resources and thoughts ruling the society, as well as the awareness of the progress, different needs were felt compared to the past. They saw meeting these needs and the solutions in following the Western methods. The establishment of Dār ul-Funun, sending students to Europe, hiring foreign teachers and publishing newspapers, triggered a change in social and political attitudes during the Qajar era. The atmosphere ruling the architecture of Qajar era also followed the same attitude. From the middle of Naser al-Din Shah era, the confrontation between tradition and modernity gradually led to the victory of modernity, and architecture lost its old forms and found on a western form. It seems that the frequent trips of the Qajar kings to Europe left a significant impact in the field of architecture. The kings and princes wanted to implement the western architectural design in their land. Western examples also quickly became popular among the people and all over Iran. This architecture is characterized by the protruding and columned main entrance and grand ceremonial stairs, and the rooms are built in two wings on the first and second floors. The customs buildings in Bushehr Province were built at the end of the Qajar era and the beginning of the Pahlavi era, and they were among the first buildings in Bushehr Province that appeared with a different architecture, and their design is not derived from the architecture of that period, but it is influenced by the architecture of the West, and due to extensive connections of Bushehr with other countries, the role of foreign architects has been prominent in this province. Care should be taken in order to preserve valuable buildings such as these customs building which were studied in this article, so that they are not destructed.

Abstract
the beaches and hinterland of the Persian Gulf are a large part of southern Iran, which has been of interest throughout history, and many settlements have been formed in thispart of iran. This semi-closed sea has a great value in terms of natural and economic situation and military and political situation Just as the economic and social life of Mesopotamia depends on its two waterways, the Tigris and the Euphrates, and just as the Nile River plays the main and key role in the history of Egypt, in the same way the Persian Sea can be considered an important and vital bottleneck of history and civilization and Iran’s economy. Over thousands of years, this azure and fertile sea has opened its arms to   Iranians and other neighboring nations like a table full of blessings, so that the residents of its shores can benefit from its diverse reserves. The present research has focused on the introduction of pottery objects known as Gopal, which are found in abundance in the southern part of Iran, especially in the beaches and hinterland of the Persian Gulf. In this research, two library methods and field visits to some areas of the studied area have been used to collect information. The main questions of the present research are: To what period of time can the Gopals be dated? What is the use of Gopal? In what areas are the Gopals distributed? In addition to introducing Gopals and examining their technical features, the use and relative dating of these objects are discussed and the distribution map of these objects in the plateau of Iran is presented.

Introduction
As a historical and strategic waterway, the Persian Gulf has always been the focus of rulers and throughout history, it has been the place of passage for the ships of Eastern and Western civilizations. The coast of the Pars Gulf is a suitable habitat for the settlement and establishment of human societies. In recent years, as a result of the archaeological surveys of the beaches and hinterland of the Pars Gulf, many prehistoric, historical and Islamic sites and hills have been identified. Among these, a number of ancient sites and mounds of clay objects have been found, which are called Gopal. The present research has studied these objects that are scattered on the banks and back banks of Pars Gulf.
Research questions: In this research, the most important questions include: 1- In what regions is the range of distribution of clay objects known as Gopal? 2- Are Gopals produced in the northern part of the Persian Sea? 3- Do these objects have different types in terms of appearance? 4- Gopals belong to what period of time? 5- What is the use of Gopal?

Gopal classification
Clay objects known as Gopal are clay cylinders whose height varies between 15 and 30 cm and their weight varies between 1 and 4 kg. The upper part of the Gopals is round with a diameter of 10 to 17 cm and the lower part is saucer-shaped with a diameter of 6 to 12 cm. Their floor is rough and uneven, but they are stable to be on the ground. Williamson has introduced the Gopals with the title of base and divided them into four categories, Gavbandi type, Bushehr type, Ganaveh type and Tepe Yahya type (Williamson 1972: 100). According to technical specifications and appearance, Gopals were classified into 9 types. But since this study is mostly in the form of a library and the distribution area of Gopals has not been fully investigated in the field, it is possible that there are more and different species that are hidden from the authors of this study.

Distribution of Gopal in the Persian Gulf
The basis of the study of the distribution of Gopals is the study of survey reports, records and field studies (Table 1) that have been published and published so far, as well as the authors’ visits to a number of sites on the beaches and hinterland of the Pars Sea. The distribution map presented in this research is the beginning of a way to carry out additional studies in the field of these clay objects in the future and undoubtedly has some shortcomings (map 1). The distribution of this pottery was in the beaches and hinterland of the Persian Gulf as Louis Pelly says: they are found along the coast (Pelly 1863-1864: 44). Hertzfeld He writes: “Along the shore, under the ruins of early Islamic houses, large quantities of clay handles are found, which are called Gopals, and are introduced as flakhen, (Herzfeld 1926: 260).
The most distribution of Gopal in Behbahan city is in Zidon section. The Gopal area in the south of Omidieh belongs to the middle Islamic centuries, of this Gopal as “Clay base” (Sadeghi Rad 2018).
In Bushehr province, the distribution of these pottery objects increases significantly and they are found in abundance in almost all of the province. Gopals of different types have been reported from the grounds of Sarkho Castle, Shahzadeh Mohammad Darvishi in Shanbeh and Tasuj sections of Dashti city (Zarei 2018: 143).
In the north-west of Fars province, two samples were introduced from Tell Ahangaran and Tell Khazaneh in Noorabad Mamsani in the study of Askari Chavardi, the first sample is Gopal made of stone. In the west of Fars, in the area of Fathabad in Sarmashed of Kazeroon city, in the research of Parsa Ghasemi, broken samples of Gopal clay were reported, which are “scattered in the plowed lands” (Ghasemi 2010: 327-327).  In the southern part of Fars province, the distribution of Gopals is more and these objects have been reported from six sites. Golrokh hill is located in Chahorz district, Lamard city, (Askari Chavardi, Amiri: 2002) A small round base was found on the surface of Tape Yahya, probably from the second period (Achaemenid period). This type, which is scattered throughout the Jiroft region, can be easily distinguished from the 3D type, and it may be considered the background of the Sassanid foundations.” (Williamson 1972: 100) and in the southern part of the Persian Sea, he refers to Al-Ain in Abu Dhabi, where Bushehr-type clay foundations are scattered there (ibid.).

Examples similar to Gopal
In terms of the overall shape and appearance of the Gopals, there are similarities with objects such as decorative studs obtained from Chaghazanbil, and probably those who consider these objects to be architectural decorations because of the similarity between There were Gopals and studs (Figure 13).
The example of a fire pit (Figure 14) which Mustafavi believes is related to the Seleucid period (Mustafavi 1968: 71) or the base of fire pits made of stone or plaster from Weigal (Javari and Bagh-Sheikhi 2019), Plang-Gard (Alibeigi 2012: 201), Shian (Moradi 2009), Bandian Derghez (Rahbar: 2008), Imamzadeh Mohammad (Askari Chavardi 2010), Tell Shahid, Keshto village and Brazjan (Tawfiqian 2017) and the images of firetemple on the coins of Sasanian kings. , have general similarities with Gopal (Figure 14).
Williamson introduces a type of wooden bases that are painted and were used for Bushheri or Kuwaiti boxes, and these clay bases are the background of wooden bases (Williamson 1972).
A type of tallow burners that became very popular in the Islamic period (Wilkinson 1973) are examples similar to Gopal. Two stone objects have been found from Imamzade Abdullah in Shushtar, which Ahmad Eghtari refers to as fire pits or the base of fire pits belonging to the Parthian period. He classified them except Gopal (Eghtari 1996: 703-702). (Figure 15). Unglazed candlesticks with a similar design have also been found in Merv (Wilkinson 1973: 314) (Figure 15). In Hormozgan province, there is a type of embroidery called Shakbafi, for its weaving and production, they use a tool similar to gopal, called Choghn. A cloth is placed on it (Figure 16). The material of this mortar is sometimes wood and sometimes clay or plastic, which is actually considered a support for a pillow and a base for weaving a tape” (Mokhtari-Dehkordi, Asadi Farsani 2013: 39).

Dating and use of Gopal
Without conducting detailed experiments and extensive and methodical studies, the dating of Gopals will be relative, it is also necessary to know the use of these clay objects in the hills and areas where they are widely produced and used. Methodical archaeological excavations should be carried out. There are many theories and assumptions about the use of Gopals. Lt. Col. Lewis Pelley, says about the Gopals: “I picked up some spirally grooved cylinders of baked clay. Traditions say that these cylinders were the ones that the infidels used to use a leather strap to attack. They threw targets” (Pelly 1863-1864: 44). After pointing out Poly’s opinion and its illogicality, Haynes Gaube mentions these objects as architectural decorations and the limitations of this assumption are listed, including why they are found in Siraf but not in Khuzestan? (Gaube 1980: 384). Herzfeld believes that the use of Gopals is similar to the Assyrian clay studs, whose ends were placed in Diora (Herzfeld 1926: 260). Williamson believes that the Gopals were used as bases for holding wooden chests known as Bushheri or Kuwaiti chests, and later they were replaced by painted wooden bases (Williamson 1972: 101).
Parsa Ghasemi believes that these terracotta objects had an architectural use, similar to the columns used in the Achaemenid building of Dahane Gholaman (Ghasemi 2009: 86). Askari Chavardi mentions clay Gopals as the base of Sasanian vessels (Askari Chavardi 2012, Askari Chavardi 2018) and the type of stone that he considers as the base of the hearth (Askari Chavardi, Pots, Pitri 2013: 149-148).
During a conversation with the residents of Shahr-e Viran in Dilam city, they stated that the nomads use these pieces of clay for weaving ni-chit (Chiq or Chikh) (Figure 17), and it was believed that these tools are used for production Nothing has been used. Kamiyar Abdi believes that these clay objects have industrial use (Abdi 2007).

Conclusion
During this research, the existing Gopals were classified into 9 categories according to their appearance and technical characteristics, their exact typology requires a systematic archaeological investigation in the distribution area of Gopals in the banks. And then the beaches of the Persian Glf. The present studies showed that Gopals are mostly found in the sites related to the Sassanid and Islamic periods.
According to the terminology of Gopal or Gopal, it is not true that this pottery object has a war function, and probably only according to its appearance, they put the name of Gopal or Gopal on it. According to examples similar to Gopal used in the art of embroidery, the assumption that Gopal was probably used as a tool used in sewing or weaving industries. According to the classification done, Gopals probably had various uses. As long as the Gopals are not recovered from their context, determining any use for this clay object will be more of a hypothesis.
