Rovinj/Rovigno (Croatian pronounced [rǒʋiːɲ]; Italian: Rovigno, Ancient Greek: Ρυγίνιον (Ryginion), Latin: Ruginium) is a city in Croatia situated on the north Adriatic Sea with a population of 14,294 (as of 2011). Located on the western coast of the Istrian peninsula, it is a popular tourist resort and an active fishing port. Istriot, a Romance language once widely spoken in this part of Istria, is still spoken by some of the residents. The town is officially bilingual, Italian and Croatian, hence both town names are official and equal.
Rovinj/Rovigno was already a settlement of Venetian or Illyrian tribes before being captured by the Romans, who called it Arupinium or Mons Rubineus, and later Ruginium and Ruvinium. Built on an island close to the coast, it became connected to the mainland much later, in 1763, by filling in the channel.
Rovigno 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.
