The Story of Falak-Ol-Aflak Castle

The great Sassanid emperors set the foundations of a city known as Shapur Khast in the 3rd century. In the city, Shapur I also built a stronghold for governing and military purposes: Falak-Ol-Aflak. Shapur Khast later went into ruins and the present Khoramabad city was founded on its remains around the 13th century. But Shapur I’s memento stayed standing as a witness to different historical periods. Since its creation, the castle has had a lot of purposes such as a place to keep Roman captives, a governing center, a garrison, a treasury, and a prison. It was also renovated several times throughout its life. Finally, in 1970, the castle was recognized as a national heritage and turned into a precious historical site. Today, you can find an anthropology museum, an archaeology museum, a conservation lab, and a traditional teahouse in the castle.

How Falak-ol-Aflak Castle Looks

On top of a hill within the borders of the city of Khorramabad, Falak-ol-Aflak is standing strongly. The gigantic towers, the high stone brick walls, and the overall grandeur of the castle don’t miss to impress you from the outside. The overall height of the structure (from the base of the hill) is about 40 meters. The merlons and embrasures (the upper sections of a castle) remind you of medieval fortresses. To get inside the walls, you’ll need to climb up a few stairs and enter through the northeastern tower.

When you get inside, you’ll see one of Falak-ol Aflak’s 2 courtyards. This is the place where the castle’s famous well and bathhouse are. Climbing further up the stairs will bless you with a nice view of the city on top of 2 of the castle’s 8 towers. Inside the castle, you’ll find 4 large halls, a few small halls, rooms, corridors, and gates. Also, you can find the second courtyard which is a bit higher than the first. This courtyard is now used as a museum. Four large towers surround each courtyard of the castle. These 8 towers are the remains of the original 12 towers that used to exist in the fortress. Mud bricks, stone bricks, stone, wood, and mortar are the materials used in the construction of the stronghold.

Archaeological studies suggest that there used to be a 2-layered defensive wall around the castle. Stretching westward, the wall is believed to have included 12 towers. The remains of two of these 12 towers still exist to the west of the castle.

The Genius Designers of Falak-ol-Aflak Castle

Khoramabad has been subject to a lot of rain. Keeping this fact in mind, the ancient architects of Falak-ol-Aflak equipped the fortress with a nice dehumidification system. The building was meant to be made of stone and wood, materials vulnerable to humidity. So, they chose the highest part of the city to build the castle. This way, wind could penetrate the building and dry its foundations. The 1-meter canals covering the area beneath the castle are in fact part of this smart dehumidification system.

The Interesting Well

In the northeast of the first courtyard, you can find the only source of water in Falak-ol-Aflak, a deep well that probably dates back to the Sassanid era. With a depth of about 40 meters, this well passes through strong rocks until it reaches a spring. In the well, archaeologists found relics from the Pre-Sassanid period. Cows were used to draw water from this well. Then clay pipes would direct water toward the bathhouse of the fortress. You can still see the remains of these clay pipes in this courtyard. What is interesting is that the well has remained usable to this day.

The Museum Complex at Falak-ol-Aflak Castle

Falak-ol-Aflak is home to two museums: archaeology and anthropology. In the Archaeology Museum, you can check out a collection of Lorestan relics from different historical eras. Interesting tombstones, and objects from Elamite, Parthian, Achaemenid, and Sassanid periods are of the charms of this museum. Objects found in the fascinating Kalmakareh Cave form part of the collection. Another part of the collection belongs to precious artifacts that thieves accidentally found in the castle. Apparently, when Alexander the Great invaded the country, the rulers of Lorestan hid valuable objects in Falak-ol-Aflak. These objects remained hidden until a couple of thieves accidentally found them about 2000 years later.

As another part of the complex, the Anthropology Museum beautifully features the customs, lifestyle, and clothing of the people of Lorestan. You can go to the depth of the culture and see the way people used to and may still live in the Lorestan region by watching the charming scenes created by wax figures.
