Overview
Petrovaradin is a historic town in the Serbian province of Vojvodina, now a part of the city of Novi Sad. As of 2011, the urban area has 14,810 inhabitants. Lying on the right bank of the Danube, across the main part of Novi Sad, it is built around the Petrovaradin Fortress, the historical anchor of the modern city.
Name
Petrovaradin was founded by the Celts, but its original name is unknown. During Roman administration it was known as Cusum. After the Romans conquered the region from the Celtic tribe of Scordisci, they built the Cusum fortress where present Petrovaradin Fortress now stands. In addition, the town received its name from the Byzantines, who called it Petrikon or Petrikov (Πετρικον) and who presumably named it after Saint Peter.
In documents from 1237, the town was first mentioned under the name Peturwarod (Pétervárad), which was named after Hungarian lord Peter, son of Töre. Petrovaradin was known under the name Pétervárad during Hungarian administration, Varadin or Petervaradin during Ottoman administration, and Peterwardein during Habsburg administration.
Today, the municipality is known in Serbian as Петроварадин, in Hungarian as Pétervárad, and in German as Peterwardein.
