Petrinja is a city in central Croatia near Sisak in the historic region of Banovina. West of Petrinja is Petrova gora (Peter's mountain), site of the Battle of Gvozd Mountain between King Petar Svačić of Croatia and Coloman of Hungary.
The town itself has been through a very grave destruction. Beholding Croatian identity, many monuments have been erected in memory of the Croatian war heroes and victims of the war.
In reconstructing and rebuilding their town, the inhabitants of Petrinja took great care of the town's urban tradition by keeping the old customs alive, celebrating Catholic holidays, and organizing numerous cultural, social and sports events. There is a very lively tradition of the potting and ceramic crafts, which represent the main souvenir production of the items characteristic for this area, all made of high quality clay. The main souvenir is "stucka", an ornamented multi-use jar made of clay that has become a symbol of the town of Petrinja..
