Peroj is a village in the Vodnjan municipality on the south-western coast of Istria. 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.
In 1562 the town had been emptied due to malaria and plague, and Leonardo Fioravanti from Bologna brought to the area 124 families of farmers from the Romagna region of present day Italy, some of which settled in Peroj. However people from Pula felt their territories had been violated and began a series of persecutions which lead the families to leave the area.
