Rovinj is a city in Croatia, situated on the north Adriatic Sea, with a population of 14,294 (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.
From 1283 to 1797, Rovigno was one of the most important towns in Istria governed by the Republic of Venice. During this period, three town gates were constructed and Rovinj was fortified by two rows of defensive walls, remains of which can still be seen today. Nearby the Rovinj/Rovigno pier one can find one of the old town gates, the Balbi's Arch, dating from 1680, and a late-Renaissance clock tower. The first city statute was proclaimed in 1531.
