The town was built on a cliff over the Kupa river and the first mention of it dates from 1244, as a free royal town. The Frankopan family owned it since 1398, then it passed to the Zrinski family in 1550, and it stayed theirs until 1671. The city commemorates 30 April as its day, in memory of the event in 1671 when Petar Zrinski and Fran Krsto Frankopan were executed. The Nastamba discovered, on the cliff above Kupa, complete clay pots and tools dating back to 3000 BC the oldest or their kind in this part of Croatia. Various objects from the Bronze Age, the period of the Roman Empire, and the Middle Ages were also found.
