Аннотация:This article contains the results of an analysis of the stone material found during the geological research of one of the hydrotechnical structures in the Phanagoria harbor (Taman peninsula, Black Sea). Because of the lack of building stone deposits on the peninsula, large amounts of stone had to be imported. The goals of our researchwere: 1) to determine the volume of stone used during the construction of the ‘Eastern Pier’; 2) to identify the type of rock and its provenance; 3) to estimate the scale of stone import to Phanagoria. It has been established that about 50 % of stone material came from the Crimean-Caucasian region, while the rest of it originated in other regions,including the Southern coast of the Black Sea and the Aegean islands.
