Guldursun Kala is a fortified town. The exterior walls and towers date to the 12th century CE. Much ancient and medieval pottery and many bronze items and coins were found within the site during archeological excavations. The coins indicate that the last period of occupation is related to the year 1220, during the rule of Muhammad Khorezmshah and the time of the Mongol invasion of Khorezm.

Janbas Kala has one of the most archaic fortification systems dating from that Early Antique period. All four of its flanking walls are in relatively good condition, reaching in places up to 20 meters in height. Janbas Kala differs from most of the other fortresses in having no towers on its outer walls. This meant that the fort was potentially vulnerable from an attack on the lower sections of its walls. The military architects had attempted to overcome this design weakness by including some steeply inclined loopholes so that some archers could fire down along the face of the walls.

Ayaz Kala is the one of the most spectacular fortresses in the area. There are in fact, not one but three fortresses clustered together on and around a prominent hill at the Eastern end of the Sultan-Uiz-dahg range. The fortress provided defense against nomad raids. A gravel road leads up to a small cluster of Yurts, a tourist rest center overlooking a shallow but picturesque lake. It was probable founded in the Afrighid period, sometime around the 7th to 8th Centuries CE… There is a lake – Akchakul Lake between Toprak and Ayaz Kala. There are also Yurt camps and restaurants next to the lake where you can enjoy local meals and drinks. In summer time it is possible to enjoy swimming and sand bath in Akchakul Lake.

Kizil Kala was originally constructed in the Late Antique period, 1st to 4th centuries CE, but was abandoned and then rebuilt in the 12th-13th centuries on the eve of the Mongol invasions. There is some debate about how this fortress may have been used in ancient times, with some scholars proposing that it was a garrison barracks for troops, whilst others suggest it was an early example of the many fortified manor houses that were typical of Khorezm in the early medieval periods After visiting all seven fortresses, it is about 90 minutes to drive back to Khiva.

Duman Kala composed of three adjacent sections – a square-shaped western enclosure with corner towers; a smaller square-shaped citadel; and an irregular four-sided northern enclosure, the remains of which can no longer been seen. The western citadel is the best-preserved section, especially along its northern side, but only small section of the eastern enclosure remains

In BC, the Amudarya (Ox) flowed in two directions, the first being the Akcha River and the second being the Suvyorgan River. The reason why this part of the river is called Akcha was the Akchakhan Fortress on the left bank of the present-day Akchakol, and it still exists today. The name of the castle is named after the ancient queen of Khorezmshahs Akchahon. After the river changed its course, the present-day Akchakul Lake was formed and it retained its name. The lake has beautiful landscape around together with fishery house and restaurant.
