Castellum Onagrinum Archaeological Site, Begeč

Castellum Onagrinum is a Roman military fortification on the left bank of the Danube in Begec, Serbia, built as a bridgehead opposite the fortress of Bononia (Banostor) [1] [2]. Excavations in 1967 and 1974-75 uncovered parts of the southern rampart, a defensive tower with semi-circular foundations, and massive footing slabs indicating a pier on the Danube bank [1] [2]. The site also contains a Sarmatian necropolis on the northern side and a late medieval/Migration Period necropolis to the south [2]. Part of the fortress was covered by a flood defence levee in 1965 [2]. The site has been on the Cultural Heritage of Serbia list since 1995 [2] [3].
