The Most Beautiful Castles, Palaces and Fortresses in Iran
6 places · updated 13 October 2026
In short: By our ranking, the most beautiful castles, palaces and fortresses in Iran are Ali Qapu, Takht-e Soleyman and Golestan Palace. The list covers 6 castles, palaces and fortresses. Last updated 13 October 2026.
Iran's palaces and fortresses span more than two thousand years of Persian kingship. Sasanian rulers built fortified sanctuaries around sacred fire, mountain peoples raised castles of brick and stone in forested valleys, desert towns sheltered behind walls of mud brick, and later the Safavid and Qajar dynasties created palaces of painted wood, mirror work and tile set in gardens and around reflecting pools.
In Isfahan, the Safavid capital, the Ali Qapu palace overlooks Naqsh-e Jahan Square from a high columned terrace, and its upper music room is lined with plaster cut into the shapes of vessels, which also softens the sound. Nearby, Chehel Sotun, completed under Shah Abbas II in 1647, has a porch of twenty slender wooden columns that are doubled by their reflection in the long pool before it, hence its name, Forty Columns. In Tehran, the Qajar Golestan Palace dazzles with mirrored halls and tiled courtyards.
The older and wilder sites balance the courtly ones. Takht-e Soleyman in the northwest is a Sasanian royal sanctuary built around a fire temple on the rim of a spring-fed lake. Rudkhan Castle in Gilan climbs a forested ridge with brick walls and towers reached by a long stairway through the woods. In Kerman province, the Rayen Citadel is a great fortified town of adobe, with walls, towers and a governor's quarter rising from the plain at the foot of the mountains.

01 Ali Qapu
Iran · 5.4 km from Isfahan32.657° N 51.677° E
Amir Pashaei · CC BY-SA 4.0 From the square the palace reads as a tall block of six storeys, about 48 metres high, fronted by a deep raised veranda, the talar. Its flat wooden ceiling rests on eighteen slender wooden columns, and from here the shahs watched polo, parades and horse races on the ground below, and on the top floor they held receptions and banquets.
Did you know? Besides receiving ambassadors, the building housed government offices: its first floor served as the royal chancellery.
02 Takht-e Soleyman
Iran36.605° N 47.234° E
- UNESCO World Heritage
MahmoudReza Nourani · CC BY-SA 4.0 Excavations have found traces of occupation from the Achaemenid period in the 5th century BC and of Parthian settlement, but the great age of the site began under the Sasanians. Here stood Adur Gushnasp, one of the three Great Fires of the empire, dedicated to the warrior class; Sasanian rulers came to honour it before taking the throne. Coins of the Sasanian shahs and of the Byzantine emperor Theodosius II have been found among the ruins.
Did you know? Shah Khosrow I reportedly visited the fire before a military campaign and gave the temple part of the tribute paid to Persia by the Byzantines.
03 Golestan Palace
Iran · 0.7 km from Tehran35.680° N 51.420° E
- UNESCO World Heritage
Parsa 2au · CC BY-SA 4.0 What makes Golestan unforgettable is the way Persian craft meets nineteenth-century Europe. The courtyard facades are sheathed in painted glazed tiles, and the interiors glitter with ayeneh-kari, the Iranian technique of setting thousands of small mirror fragments into faceted vaults so that a room dissolves into light. The Mirror Hall is the famous example, a room the court painter Kamal-ol-Molk made the subject of one of his best-known works.
Did you know? The Salam Hall, later used as the throne room for receptions and coronations, was originally designed as a museum.
04 Chehel Sotun
Iran · 5.5 km from Isfahan32.657° N 51.672° E
- UNESCO World Heritage
Zenith210 ( talk ) ( Uploads ) · CC BY-SA 3.0 The name hides a pleasant riddle. The tall entrance porch stands on twenty slender wooden columns, each made from a single plane-tree trunk, and when they are reflected in the long pool in front of the pavilion the twenty become forty. In Persian, forty also simply means "many".
Did you know? In the Qajar era the governor Zell-e Soltan turned part of the palace into a workshop for tentmakers, and the building came close to demolition.
05 Rudkhan Castle
Iran37.064° N 49.240° E
Hosseinronaghi · CC BY-SA 4.0 The fortress is usually traced back to the Sasanian era, and it was rebuilt in later centuries; it was held by the Nizari Ismailis, and the Seljuk period saw further work. A major reconstruction, carried out between 918 and 921 of the Islamic calendar (the early sixteenth century), is attributed to the local ruler Amira Hesam al-Din Dabbaj of Fuman, which explains another of its names, Qal'eh Hesami.
Did you know? The castle's main water source was a spring inside the walls; it dried up after an earthquake and was later brought back to life by Iran's heritage authorities.
06 Rayen Citadel
Iran29.593° N 57.438° E
ninara · CC BY-SA 2.0 The precise age of the citadel is uncertain. It is generally believed to be at least a thousand years old, and its foundations may go back to the Sasanian period, before the coming of Islam; much of what stands today was expanded and strengthened in later Islamic centuries. Its plan and building techniques show the hallmarks of the classic Iranian citadel, with a fortified town of houses and lanes protected by towered walls.
Did you know? According to tradition, Arab armies failed to take Rayen in the time of the last Sasanian king, Yazdegerd III, thanks to its high walls.
How this list is ranked
Places are chosen for how they look, not for how famous they are: each one has its own description and a photograph credited to its author. The order is a single world ranking that weighs the beauty of the place in curated photography together with how widely it is documented — the number of language editions of its encyclopedia article and how often that article is read in a year. The list is rebuilt as places are added, so the order and the counts on this page are always current.
