Toprak-kala
I would love to share the historical lineage of this area, but it gets incredibly complicated with more conquests than you can imagine, so we will stick with the basics here.

The archaeological site of Toprak-kala (1st-4th centuries CE) was discovered in 1938. Toprak-kala had a population of around 3,000 people and was the principal city of one of the local dynasties. Established by the Khwarazmian-speaking people who inhabited a large oasis region on the Amu Darya River delta.

The Toprak-kala site (translates as ‘the earthen fortress’ or ‘the dusty fortress’) took the form of a rectangle and was surrounded by walls 65 feet tall and 39 feet thick with numerous square towers. All the buildings in Toprak-kala were made of large mud bricks. It is assumed that the Khorezmians possessed specialized architectural knowledge that allowed them to construct highly durable structures from ordinary clay that still remain after many centuries of use. They reinforced their buildings with small rocks found in the desert, and the river sand they used absorbed moisture, keeping the rooms dry.

The northwestern part of the fortress was occupied by the ruler’s large palace.
In the center is the remains of a very large temple of fire.

The residential part was divided symmetrically by a main street with residential blocks on each side. Each block consisted of an uninterrupted complex of residential rooms, without any division into separate houses. The number of rooms in one such block might reach 200.

And I found this
In the 5th century, it appears that the people left the city, and the site was converted into a large necropolis with numerous ossuary burials. There are two thoughts as to why. The first was for political reasons, the second was that the Amu Darya River changed its course, thus their water supply was gone.

Excavation of Toprak-Kalar revealed unique finds of the ancient Khorezmian language at four buildings. Archeologists found 116 documents written in black ink on wooden tablets and leather rolls. Though not yet fully deciphered, they have been identified as economic documents from the palace archive. Three of the documents found had precise dates: 207, 231, and 232 CE.

The monument ranks among the oldest cultural sites in Central Asia and is a UNESCO World Heritage Site.

In 2003–2007, archaeological excavations were carried out at the Toprak-Kala site and at the Meshekli caravanserai and its surroundings. As a result, one of the oldest Zoroastrian temples in Central Asia was discovered.
Fragments of ossuaries, possibly Zoroastrians’ canopic jars, were found within Toprak Kala.
Ayaz-Kala

Ayaz-Kala is a complex archaeological site, consisting of three phases of fort construction located on the edge of the Kyzylkum Desert.
The fortresses were built from the 4th century BCE to the 7th century CE, also by the Khwarazmian-speaking people, with each fortress designated as Ayaz Kala 1, Ayaz Kala 2, and Ayaz Kala 3.
Ayaz-Kala was part of a defensive line protecting agricultural settlements against nomadic raiders, including the Saka people from the northern and eastern Eurasian Steppe.
Ayaz Kala 1, the highest of the three, was constructed in the 4th century BCE on a flat section of a limestone hill that commanded a view of the surrounding plains. The fortress had been used for over five hundred years.

Ayaz Kala 1
The structure is about 600 x 500 feet. The outer walls used a double-wall construction, with the inner and outer walls separated by a six-foot-wide arched corridor.

The roof of the corridor formed a platform on which archers and other defenders could stand. The upper part of the outer wall had slits through which the defenders could fire their arrows.

Ayaz Kala 1 and the slits for arrows
There is no evidence of any permanent buildings having been constructed inside the fort, even though the space within the fortress is quite large. There is, however, evidence of a water storage tank to store collected water.
For this reason, the fortress may have acted as a refuge for local residents rather than housing a resident garrison, permanent residents, or a palace complex. Presumably, occupants of the fort and those who sought to take refuge within its walls could have used temporary dwellings such as yurts.

Ayaz Kala 1
Since the site has not been systematically excavated or scientifically dated, it is not known when Ayaz Kala 2 was constructed, though it is thought to be the most modern of the three kalas. Estimates of when different parts of the kala were built range from the 4th to the 8th centuries CE. The palace-fort complex could have remained in use until, say, the Mongol invasions of the 13th century CE.

Ayaz Kala 2

It is the smallest of all of the sites, leading to the theory that it was a fortified residence of a feudal landlord.
Ayaz Kala 3, a garrisoned fort, was the largest of the three kalas. It was surrounded by agricultural fields. There is evidence of old farmsteads and field boundaries. Kala 3’s location would have made it far more accessible than Kala 1 in an emergency, such as a sudden attack. Kala 3 contains a fortified building in its northeast corner that dates to the 5th and 4th centuries BCE. The outer walls may have been built later, between the 1st and 2nd centuries CE. This kala, located as it were at the edge of the plains, would have complemented kala 1 in defending the area and providing refuge.

Ayaz Kala 3
Ayaz Kala 3 was constructed in the shape of a parallelogram with square towers at each corner and rectangular towers defending each side. The entrance was in the middle of the western wall and was defended by a strong defensive tower.
Regrettably, as was the case with most archaeologists of the era, their interest seemed to be in making discoveries and then abandoning the sites, leaving them unprotected and exposed to harsh environmental conditions and unregulated foot and animal traffic. The methods some used included bulldozers. The excavated ruins have become badly eroded over the past thirty years.

A touch of green in a very barren location.

The origins of Konya Ark can be traced back to the 17th century when the khans began to build their own fortified residences within the walls of Ichan-kala. However, the structure that I saw dates mainly from the 19th century.
There were also workshops to make weapons, a palace kitchen, stables, a winter and summer mosque, and even a prison.


The Wooden throne of the khan, built in 1816, was gilded in silver and traditionally sat where this replica sits today. It was carted off by the Russians to the Hermitage at the time of their taking over Uzbekistan. The Uzbeks are still trying to negotiate its return.
