The Shusha fortress (, ) or Shushi fortress () is a fortress surrounding the historical centre of Shusha. The newly conquered castle town was called "Panahabad fortress" named after Panah Ali Khan who together with Melik Shahnazar was the founder of the fort. In later years, the city was just called "Fortress". A settlement at Shusha is first recorded in a 15th-century illustrated Armenian gospel which mentions the "Shushu village".Boris Baratov.

The area where the Shusha fortress was built is a mountainous plateau in the form of amphitheater from the west with numerous hills and rifts. The highest area of plateau is 1600 metres and the lowest area is 1300 metres above sea level. At present, the territory of Shusha city consists of plateau with a hill located lengthwise in its center. The architecture of Shusha fortress represents basic principles of architecture of feudal period in terms of both the choice of location, structural planning and the artistic appearance of the fort.

Shusha fortress had three main gates: Ganja Gate, Iravan Gate and Aghoghlan Gate. The names of all these gates are often mentioned in historical sources, as well as in all the drawn plans of 19th-century Shusha.

History

Historical and political situation Following the assassination of Nader Shah () in 1747, internal chaos erupted in Iran, particularly in the South Caucasus, where semi-autonomous khanates emerged as a result of the lack of a centralized government, one of them being the Karabakh Khanate. Each of these khanates, which was implementing their own policies and trying to develop their economy, had a center to control the areas that was under their supervisory. This period was associated with several complicated events in the military-political history of the South Caucasus. Some of them are as follows:

1. Forty Years’ War (1709–1749) had not yet ended.

2. The wars and the uprisings of peasants in feudal society were frequent.

3. The region was being attacked by Turks and Iranians.

In such a situation, khanates were mainly in need of a well-fortified capital city because they had to maintain their territorial integrity and political independence. Therefore, the construction of such fortified cities was primarily driven by the demand of military-political situation.

Panah Ali khan who founded the Karabakh Khanate with the support of Armenian Melik Shahnazar in 1747 decided to build a fortress which would help him to control this large country extending from The Aras River to Lake Sevan, from The Tartar River to Meghri, Tatev and Sisian and including the areas of Karabakh, Zangezur and Bargushad. In 1748, Panah Ali Khan ordered to start the construction of Bayat castle near Barda. Panah Ali Khan were willing to build "a fortress where his family can live and he can protect the people in the case of invasion by enemies". Therefore, Bayat castle was surrounded by deep ditches and thick exterior walls.

Bayat castle, which was built with fired bricks, features Khan's palace, mosque, bazaar, bath and houses. Following the settlement of Khan's family in Bayat, artists from nearby villages as well as Ardabil and Tabriz moved here. However, Bayat did not remain as Khan's residence for a long time. Despite numerous reinforcement efforts, the castle was still weak against the attacks of foreigners. Taking into account the threat, Panah Ali Khan started to look for a strategically more favorable area to build a new fort. As a result, the area of Ternekut best known as Shahbulag, which was a foothill located near Shahbulag spring (10 km away from Aghdam), was preferred.

The 19th-century Karabakh historians stated that fortress, stone houses, mosque, bath and bazaar was built in accord with Panah Ali Khan's instructions. The information related to the construction of civil and religious buildings in Shahbulag can be found in the works of Mirza Yousif Karabakhi and Mirza Jamal Javanshir. M. J. Javanshir noted "In the section about monuments and buildings erected by the order of deceased Panal Ali Khan" in his "The History of Karabakh" book: "Shahbulag fortress, mosque near the fort, bath, other buildings and bazaar were built by the order of Panah Ali khan". The khan, who moved to a new castle and fortified his positions, instructed to destroy his former headquarters.

Construction in the area of Shahbulag, especially the architecture of castle and mosque, had a significant impact on the subsequent building process in Shusha. Almost all fortresses in Shusha used the features of the Shahbulag castle again in terms of architectural planning and the structure of volume-space. Later, however, the relatives of Panah Khan advised him to choose a safer place for the construction of a new fort and thus he decided to build Shusha fortress.

Construction

Ahmad bey Javanshir noted that "The eternally impassable, inaccessible place chosen for construction of the fort would not allow even the strongest enemy to besiege it". The construction of a new fortress required such a location that one of its sides would be open to be in contact with elats as well as would provide Panah Ali Khan with a chance to get in touch with mahals under his control.

"The sole place in whole Karabakh was Shusha lowland, which was a natural fort surrounded by inaccessible rocks". Baharli, the historian of Karabakh, stated that the space selected for the construction of the new fort was surrounded all around, except the east, by dense forests. The area of the fortress is divided into the ravines completed by valleys. The ravines allow natural water to flow out of the fortress, so it reduces the possibility of flooding to zero in Shusha, where the rainy and foggy weather is characteristic.

Due to the lack of flowing water sources in Shusha plateau (except a few springs), numerous groundwater wells were drilled to meet the needs of the castle population for water. One of the most important features of the Shusha plateau was its richness of well-hewn stones used for construction and forests. All of these played an important role and had a great value as local building materials for the construction of the fortress.

Although the fortress walls were vital to the city during the continuous feudal wars, their construction required to spend a large part of the city budget. The choice of a mountainous area for the construction of the town of Shusha also allowed to save some money for the construction of the walls. Rocky cliffs caused an inaccessible environment in almost two-thirds of the defense system. Therefore, Shusha is one of the best examples of how the strategic factor influences the choice of territory.

The testimony of many witnesses proves the success of the site chosen for the construction of the fortress. G. Keppel, the famous English traveler who visited Karabakh in the 19th century, noted the successful strategic location of the Shusha plateau. He writes: "The natural superior position – the location in the almost inaccessible peak of the high hill – caused the need for human defense to play a less important role in the city." Count Platon Zubov who described Shusha fortress at the top of the Caucasus Mountains also stated its natural strategic advantage. The high cliffs surrounding the Shusha plateau on three sides – south, west and east – rise above each other in different directions and they are "completely inaccessible" from all the sides except the north. The height of the rocks surrounding the Shusha plateau even reaches up to 400 meters in some places.

Russian military historian Vasily Potto described 48-day defense of Shusha against the army led by Qajar crown prince Abbas Mirza and also noted the topographical characteristics of Shusha: "The fort, which was in a dilapidated condition but impassable due to its position, was not in need of a complicated defense plan." One of the advantages of the site chosen for the construction of the fortress was the good observation and control of all the surrounding areas, which prevented a sudden attack of the enemy. P. Zubov writes: "It is possible to observe the villages, which are scattered along the valley and located on the farthest side from the perspective of Shusha plateau, beautiful vineyards and mountains covered with forests."

V. Potto and A. A. Caspari who was speaking about the natural impregnability of Shusha fortress also noted that the cliffs which rise to the top, especially in the north-eastern part of the city. They stated that due to these cliffs, "even a few people would be enough to prevent an army consisting of a large number of soldiers as in ancient Thermopylae". The road from Shusha fortress to Ganja fortress was located on the slope of the mountain. In the 1870s, the measures were taken to straighten this steep road hindering the development of the economy in Shusha. For this purpose, some rocks which was difficult to pass were destroyed by blasting. V. Vereshchagin, who visited Shusha in 1864–1865, described the difficult, steep, sloping road where five horses hardly pulled a cart.

The newly built fortress-city was named Panahabad fortress named after its founder Panah Ali Khan. Later, the city was simply called "Fortress". After a while, the people called the fortress as Shusha fortress, and later only Shusha. The name "Shusha" was probably derived from the name of Shushikend, which is near the place where the fortress was built.

There is no exact information regarding the definite date of construction of fortress. A. Alasgarzadeh and E. Shukurzadeh, who edited and published the "Karabakhname" (the important historical source to investigate the history of Karabakh Khanate), note that it is doubtful the date of the foundation of Shusha fortress was given as 1170 according to Islamic calendar. According to mentioned historians, Mirza Jamal Javanshir did not indicate the date of the foundation of the fortress correctly, and his mistake was repeated by Ahmad bey Javanshir and Mirza Adigozal bey in their own works. According to their notes, the start of the construction of Shusha fortress dates back to 1751 or the second half of 1770.

E. Avalov notes that Molla Panah Vagif, the poet and vizier of the Karabakh khan, personally supervised the construction of Shusha fortress. Karabakh historian Hasan Ali Khan Garadaghi writes: "Under the direct control of Molla Panah Vagif, several buildings including Shusha fortress were built in Shusha."

Architectural features

The area in which Shusha fortress was built is a mountainous plateau in the form of amphitheater from the west with numerous hills and rifts. The highest area of plateau is 1600 m and the lowest area is 1300 m above sea level. At present, the territory of Shusha city consists of plateau with a hill located lengthwise in its center. The plateau which turns sharply to the east reaches the hill that dominate the whole area in the west. The hill which is completed by a fault is also the center of a large amphitheater, with one wing reaching south and crossing Jidir Plain, then extends to the north from where it rounds to the south, and is completed by a ravine.
