12 Most Famous Castles and Citadels in Iran
A Journey Through Iran's Historic Castles and Citadels
Iran’s fortresses tell different stories: some guarded mountain routes, others housed royal courts or sheltered entire towns. This guide explores 12 notable castles and citadels in Iran, from the ruins of Alamut to the earthen architecture of Bam. Their dates, uses and states of preservation vary, so each deserves to be understood on its own terms.

Persian Castles: An Epic Past
Castles, fortresses and citadels served different purposes in different periods. Some protected settlements and roads; others combined defensive walls with residences, stores and administrative spaces.
Iran’s varied terrain shaped its fortifications. Rocky ridges offered visibility and natural protection, while urban citadels used walls, towers and controlled entrances. The surviving buildings reflect successive periods of construction, repair and reuse rather than one uniform architectural tradition.
The 12 sites below span several provinces and historical periods. Some are protected UNESCO World Heritage properties; others are nationally significant monuments. Check local access conditions before visiting, as restoration and conservation work can affect entry.
1. Falak-ol-Aflak Castle
Falak-ol-Aflak overlooks Khorramabad in Lorestan Province. The hilltop fortress has a long history, commonly associated with Sasanian-period origins, although its present form reflects later changes and repairs.
The castle’s towers, courtyards and commanding position above the city make it a prominent landmark. Exact measurements and the dating of individual building phases should be checked against site-specific archaeological documentation.
2. Alamut Castle
Alamut Castle stands on a steep rock outcrop in Qazvin Province, not Gilan. From 1090 it was a major centre of the Nizari Ismaili state until its fall in 1256. UNESCO inscribed Alamut Castle and Related Fortifications in 2026, recognising the wider defensive network and its cultural and intellectual history.
3. Shush Castle
Shush Castle, also called Susa Castle, rises above the archaeological site of Susa in Khuzestan Province. Unlike the ancient remains around it, this European-style fortress was constructed for a French archaeological mission around the turn of the 20th century. Its appearance should not be mistaken for the architecture of ancient Susa.
4. Dokhtar Castle (Qal-e Dokhrar)
Qal’eh Dokhtar, or Maiden Castle, stands near Firuzabad in Fars Province. Associated with Ardashir I and the transition from Parthian to Sasanian rule, it is one of the components of UNESCO’s Sassanid Archaeological Landscape of Fars Region, inscribed in 2018. The fortress occupies a defensible hillside overlooking a historic route.
5. Babak Fort (Qal-e Babak)
Babak Fort stands high in the Arasbaran mountains near Kaleybar, East Azerbaijan Province. It is associated with Babak Khorramdin and resistance to Abbasid rule in the ninth century. Reaching the remains involves a demanding uphill walk, and trail conditions can change with the weather.
6. Izadkhast Castle
Izadkhast Castle occupies a dramatic elevated site in Fars Province, within a historic complex that also includes a caravanserai and bridge. Its fabric reflects more than one period. The castle itself should not be described as a UNESCO World Heritage Site inscribed in 2007; that claim is unsupported.
7. Rudkhan Castle
Rudkhan Castle sits among the forested hills southwest of Fuman in Gilan Province. Its extensive stone-and-brick walls and towers follow the contours of the mountain. The exact date of its earliest construction is debated; visitors generally approach by climbing a long staircase through the forest.
8. Arg-e Bam
Arg-e Bam is the monumental fortified settlement at the heart of Bam and its Cultural Landscape, a UNESCO World Heritage property inscribed in 2004. The citadel preserves evidence of centuries of earthen construction and trade-route connections. The 2003 earthquake caused severe damage, followed by extensive conservation and restoration.
9. Rayen Castle
Rayen Citadel is a fortified adobe complex near Rayen, south of Kerman city. Its walls, towers and internal streets offer a striking comparison with Bam, although the two sites have distinct histories and preservation conditions.
Rayen’s chronology includes phases that require specialist study; a precise foundation date should not be stated without a reliable archaeological source. The surviving fabric illustrates how defensive and residential functions could coexist within an earthen citadel.
10. Portuguese Castle
The Portuguese Fort on Hormuz Island recalls Portuguese maritime power in the Persian Gulf during the 16th and early 17th centuries. Its red-stone walls overlook the island’s coastal setting. Explore the wider island in our Hormuz travel guide.
11. Narin Castle
Narin Castle is a prominent mud-brick fortress in Meybod, Yazd Province. Its construction history is complex and includes multiple periods of occupation and rebuilding. Claims about an exact Achaemenid foundation or views extending a fixed distance need stronger documentation.

12. Arg-e Karim Khan
Arg-e Karim Khan stands in central Shiraz. Built during the Zand period in the 18th century, it combined the functions of a residence and a fortified seat of government. Its brick walls and corner towers distinguish it from Iran’s mountain fortresses.
The citadel is associated with Karim Khan Zand’s development of Shiraz as his capital. Later administrations reused the complex, leaving a layered history that extends beyond its original royal role.
