Vukovar is the largest Croatian river port on the Danube in the Croatian part of Srijem. It is the administrative, educational, economic, and cultural center of Vukovar-Srijem County.
Vukovar is an old baroque city on the Danube, mentioned at the beginning of the 13th century as Volko, Walk, Wolkov (the Vukovo – in Croatian).
Since the 14th century, the Hungarian name Vukovar has been increasingly used, as Croatia was in a legal union with Hungary. Vukovar and the neighboring Ilok were the guardians of the Croatian identity in the Danube-Sava confluence during that period.
Vukovar lies on essential traffic routes. In the Roman period, the border road, the so-called Lime road, led along the right bank of the Danube, on which Cornacum, today’s Sotin, was an important station. Since ancient times, the Danube has also been navigated, and Vukovar is an important stop on that route.
