Lietuvos archeologija

The article is devoted to the results of the research of the fortress Tyagin, built by the Lithuanian Grand Duke Vytautas on the territory of the island Bolshoye Gorodishche in the late 14th to early 15th century. The archaeological materials provided valuable information about the syncretism of the complex of monuments on the island, the typology, layout and size of the fortress. It was one of the earliest stone castle-type fortresses on the northern Black Sea coast, a part of the defensive line of the southern borders of the Grand Duchy of Lithuania. The fortress’ defensive system included a synthesis of defensive architectural elements, ranging from timber-engineered structures known from Old Russian times to stone walls and buttresses of a new level of fortification in Europe. The fortress was armed with artillery and edged weapons, the main type being crossbows, which were widespread in Lithuania. The fortress of Tyagin was situated at the crossroads of trade routes between the East and the West, at the crossroads of the custom. The artifacts testify to the presence of Lithuanian cultural objects, Genoese influence, contact with Crimea, and trade and economic relations with Poland. The monument is an integral part of the cultural heritage of Lithuania and Ukraine.
