Begin with one landscape, not one castle

Uzbekistan’s 2008 UNESCO Tentative List entry groups eight places under the name Desert Castles of Ancient Khorezm: Toprak Qala, Ayaz Qala, Koy-Kirilgan Qala, Big Guldursun, Pil Qala, Anka Qala, Kurgashin Qala and Djanbas Qala. Read the full Tentative List record.

A Tentative List entry is a proposal supplied by the State Party, not a World Heritage inscription. It does not mean that all eight sites belong to one date or served the same purpose. Read the group as evidence of a long-lived regional system whose settlements, defensive works and social organisation changed across many centuries.

At Toprak Qala, look for city and palace together

UNESCO’s record describes a rectangular settlement of about 17 hectares, enclosed by fortified walls and towers, with a citadel and raised palace in the north. Rooms, sanctuaries, archives, inscriptions and clay reliefs were found within the palace complex. These details turn the ruins from a backdrop into evidence of administration, ritual and planned urban space.

Uzbekistan Travel presents the palace as a residence of Khorezm rulers in the second and third centuries CE and describes streets, quarters and workshops around it. See the national tourism account. When visiting, ask which walls are original fabric, which outlines come from excavation and which forms are modern conservation or interpretation.

Ayaz Qala is a group—and the dates need labels

Ayaz Qala is not a single isolated building. The official tourism record describes three settlements on separate hills, while UNESCO distinguishes the large Ayaz-1 fortress, the Ayaz-2 castle and surrounding manors. The different positions and layouts are part of the story: a high fortress, a later castle and traces of life across the plain.

The official summaries do not give one fully consistent date. One Uzbekistan Travel page dates a main fortress to the third or fourth century BCE; another says the third or second century BCE while also using a Kushan label. UNESCO instead says Ayaz-2 was constructed in the Kushan period and modified in the fifth to seventh centuries CE. Compare the short fortress page with the dated settlement guide. A careful explanation should identify the exact component and phase instead of giving the whole group one birthday.

Read the edge between oasis and desert

UNESCO’s submission repeatedly connects fortifications with the defence of oasis borders, fields and caravan approaches. Around Ayaz Qala it also describes country manors and changing social organisation. The open land is therefore not empty scenery around the monuments; it helps explain why walls, gates and lookout positions were placed where they were.

The 2022 tourism guide suggests that changing irrigation may have contributed to abandonment, but presents this as a probable explanation rather than a demonstrated single cause. Treat water history, political change and settlement movement as questions to investigate. From a viewpoint, compare the defended hill, the plain and signs of cultivation before focusing on individual bricks.

Plan the fortresses as a separate Khiva extension

Uzbekistan Travel’s 2025 regional route announcement includes Toprak Qala and Ayaz Qala among Karakalpakstan stops. That announcement shows current tourism interest; it does not confirm road conditions, conservation access, opening arrangements, guiding or services for your travel date.

The site’s suggested nine-day Uzbekistan route includes Khiva but does not automatically include the desert castles. Ask for them as an optional extension and request the vehicle plan, total driving time, start time, walking surfaces, rest and shade arrangements, water stops, guide language and any extra night in writing. Request a four-city plan with a desert-fortress option using your dates, group size and walking comfort; transport, access, guide, hotel and final price remain subject to current confirmation.
