The Akshakhan-kala is located on the right bank of the Amu Darya, in the Biruni district of the Republic of Karakalpakstan. Over the years of archaeological study of the site, a large ceramic material was collected, dating back to the 3^rd cent. BCE - 5^th cent. AC. In the archaeological collection of the site, a group of finds is distinguished, attributed to the category of building ceramics. The article is devoted to the analysis of this collection and an attempt to determine the field of application of certain types of building ceramics. Among the building ceramics of the Akshakhan settlement stand out spillway pipes and ceramic tiles. The use of fragments of ceramic vessels in the construction was also recorded. The obtained analysis results suggest that in ancient Khwarezm, ceramic building materials were used to solve such problems as protecting structures from atmospheric precipitation, improving settlements and increasing the strength of adobe structures.
