Peroj (Montenegrin: Перој) is a village in the Town of Vodnjan on the south-western coast of Istria, Croatia. Peroj originally dates back to the Copper Age of prehistory, as testified by a necropolis within the old walls of the town. The town has been settled with families from a variety of origins throughout its history. During the occupation of the Romans, the town was named Pedrolo, and was a popular holiday destination.
