The paper is devoted to organization of building of the Khazarian fortress near Semikarakorsk (the Lower Don) built of adobe (unburnt) brick. This is the first attempt to reconstruct the complete technological process from clay digging to building fortified walls. According to the author's calculations, the construction of the fortress, which was 830 m in its perimeter (the citadel itself was 340 m), with the walls not less than 1.60 m thick and up to 4.8 m high, required over 2 million adobe bricks.
