Udbina Castle

Tvrđava Udbina

Udbina Castle is a medieval fortified structure on a hill at the northern end of the town of Udbina, overlooking the Krbava field. It was an important regional stronghold that passed from Croatian noble owners into Ottoman hands in the early 16th century and was retaken in 1689; thereafter it declined and by the 19th century fell into ruin. Today only fragmentary masonry remains on the hilltop.

As it stood in 1600

What Udbina Castle looked like in its prime.

Perched on a rounded hilltop above the Krbava field, the castle centers on a tall, round bergfried (donjon) of roughly carved cut stone with an inner diameter near 7 m and wall thickness about 2–2.4 m (total diameter just over 11 m). Around the tower are three thick concentric defensive stone walls exhibiting a bastionic, earthen-embanked profile; remaining outer curtain walls are thinner and follow the hill slope, all built of local cut stone with raw, irregular masonry.

Its story

The story of Udbina Castle.

Udbina Castle stands on a hill at the northern end of Udbina, overlooking the Krbava field where the fierce and bloody Battle of Krbava between the army of the Kingdom of Croatia and the Ottoman Empire was fought in 1493. Built of cut stone, it was an important stronghold of Croatian troops during the wars of Ottoman expansion in the 15th century.

The castle belonged to the powerful Kurjaković noble family. Shortly before the battle Karlo Kurjaković, who possessed a large part of Lika including Udbina, suddenly died, leaving in the castle his wife Dorotea née Frankopan and his small son Ivan, later ban of Croatia and the last male of the line. Despite the Croatian defeat of 1493, Udbina fell to the Ottomans only in 1527, becoming their stronghold in the region.

A Habsburg-Croatian army retook it in 1689, but by the end of the 19th century the uncared-for castle had slipped into ruin. Excavation revealed a spacious round bergfried over 11 metres in total diameter with walls up to 2.4 metres thick, ringed by three thick walls built bastion-fashion against firearms, along with ceramics, burnt wooden beams and two stone cannonballs.
