Since Iran had always been attacked by hostile enemies, governments usually ordered the construction of huge and solid buildings so that they could defend themselves, their families, their King dome and their cities. Some of these structures were used militarily and some were built just to protect farmers and peasants, but all of them are only witnesses of wars and bloodshed throughout Iranian history. In this article we take a look at top ten famous castles of Iran.



Iran’s Ancient Fortresses 

Fortresses have played an important role in strengthening nations throughout history and even in prehistoric times. Castles were usually protected by governments along important roads or cities. The castles in ancient times were mostly built on high mountains or rocky slopes that served as a natural defensive factor against enemies.
Iran is no exception and has a number of unique historical fortresses. In most cities of Iran, these historic castles are found and most of them can be visited.

Falak-ol-Aflak Castle: the Sassanian legacy

Located on a high hill in Khorramabad, Lorestan province, one of the most historic castles in Iran, is a reminder of the Sasanian Empire. Falak-ol-Aflak castle is a symbol for rich history and culture of Lorestan and also Khorramabad city. The construction of Falak-ol-Falak castle –Originally called Shapur Khaast– dates back to the Sassanid era (3rd C) . The massive structure of the castle covers about 5300 square meters.

The castle is considered to be a masterpiece of Iranian creativity and intelligence. It has undergone transformations since the Sassanid period until Qajar Era (19th C) and has had multiple functions in different historical periods. Today, it is served as museums of anthropology and archeology attracting many visitors. The total area of the castle is 5300 m2 and the materials used in its construction are stone, brick, clay and a mortar made of plaster and lime. The entrance to the castle is built in the southwest tower with a width of 10 meters and height of 3 meters.

Over the centuries, the fort has been restored many times, with major changes during the Safavid and Qajar periods. According to local people and some historical documents, there used to be a two-tiered, adobe wall with twelve guard towers around the current building up to 100 years ago, of which only two towers has remained.

There are two courtyards in the castle, the first is surrounded by four towers. Two of these towers are located in the north and northwest and two in the southwest and south. The second courtyard has a similar structure to the first courtyard. On the four sides of it are large halls built into one another. This is where the museum exists today.





Alamut Castle: the well-known survivor

Hassan Sabbah (1050–1124 AD) was a Shiite Ismaili leader, an Islamic sect that was persecuted by Iranian rulers. He gathered many supporters, as he was hiding in the valleys of Alamut.

Originally, the Alamut castle was owned by local rulers but Hassan Sabbah and his followers came up with a plan that allowed them to take over the fortress without spilling a single drop of blood (Hassan reportedly even paid the repressed ruler for this place).
The castle became a stronghold for him and his men (later referred to as the Order of Assassins). They updated the castle’s water systems and fortified the defensive structures. And, perhaps most notably, they built an exquisite library full of books and scientific documents of astronomy, math, philosophy, and even alchemy.

Babak Fort: symbol of courage and defense

Babak castle (Ghal’eh Babak) is one of the largest castles in Iran, remaining from the Sassanid or Parthian period. This castle, located at the height of 2300 meters in Arasbaran forests, is the strategic place that “Babak Khorram din” and his companions settled in and defended themselves against the enemies.
It is also known as the Eternal Castle, Immortal Fort or the Republic Castle, and is referred to as a national symbol. The reason for the naming is because of the courageous defense of Babak to oppose the Abbasid Arab invaders.
Babak Castle has been refurbished several times over the centuries. Though there is not much left of the main structure, still we can imagine its glory in the past. The Babak Fortress was designed in a way that those inside the castle could defend themselves with a small number of troops against a huge army. This made Babak and his troops able to continue the struggle against the invaders for years. Like the castle of Alamut, it has only one entrance way and is surrounded by fright-full valleys. The path to Babak Fort is not easy and you have to cross some difficult passages to see this historic place. But it is still possible to reach this magnificent castle through its partially demolished stairs.

Ghaleh Dokhtar: a thousand year old virgin

Ghal’eh Dokhtar, also Dezh Dokhtar meaning “The Maiden Castle” is a castle built by Ardashir Babkan, the founder of Sassanian Empire in 209 AD.
Located 6 km from Firouzabad, on a slope in the heart of the mountains, Ghaleh Dokhtar was a stronghold and served as an important obstacle for the enemies to cross the “Tangab Gorge”. General architectural features of the palace inside this castle, in comparison with Ardashir palace in Firouzabad plain, show that the Maiden Castle was founded during Ardeshir I‘s wars with Parthians before his final victory over the last Parthian king, Ardavan V (Arthabanus V) in 224 AD.

The main fortifications of Ghal’eh Dokhtar include an outer wall that extends over a sloping cliff with an overall shape of a trapezoid. These fortifications started from the lower part of the “Tangab Gorge” and extended to the highest part of the mountain where the inner castle of the castle is located. The geometrical multi-level layout of the inner palace is in complete contrast to the non-geometrical mode of the castle itself, which is based on the natural shape of the mountain.

Arg-e Karim Khan: the king’s citadel 

Constructed in the 18th century, Karim Khan’s fortified complex in the heart of Shiraz serves as a reminder of the Zand dynasty’s influence and legacy in Persian architecture. The citadel was built in 1697 during the Zand period. As soon as the king Karim Khan selected Shiraz as the capital city, lots of significant changes were made. He invited the most famous professional architects and artists to Shiraz and asked them to build a residential palace for him.

The citadel’s design is a striking blend of military might and aesthetic beauty. Its massive walls, punctuated by robust circular towers, provided both protection and a sense of grandeur. The use of traditional Iranian architectural elements, such as delicate tile work, decorative brick, and intricate plaster molding, adorns the structures, creating a harmonious balance between strength and elegance.

Arg-e Karim Khan has had various functions in different historical eras. It served as a residential palace for Karim Khan Zand and his successors and also was the living place of some local rulers in the fallowing Qajar Dynasty. In 20th century, during the Pahlavi Rule, Karim Khan Citadel was converted into a prison and the paintings were plastered over. An arson finally destroyed many parts of the palace and it is under the renovation process to be transformed into a museum.

Today, this historical site is a must-visit for tourists and history enthusiasts, offering a glimpse into a bygone era of Persian culture and the architectural brilliance of its time. Karim Khan’s Citadel stands as a symbol of Shiraz’s cultural heritage and its enduring charm.
