Rovinj is a city in Croatia situated on the north Adriatic Sea. Located on the western coast of the Istrian peninsula, it is a popular tourist resort and an active fishing port.

Rovinj was eventually incorporated into the Byzantine Empire, later becoming part of the Exarchate of Ravenna in the 6th century, before being taken over by the Frankish Empire in 788. For the following several centuries it was ruled by a succession of feudal lords, and in 1209 it was acquired by the Patriarchate of Aquileia under Wolfger von Erla.
