History
The village became the site of a mass grave from May 23–25, 1945 when Axis soldiers were massacred there by the Yugoslav Partisans. The Wehrmacht had dug anti-tank trenches in the village, which were used to bury the dead. The mass grave was discovered in 2009. It is estimated that there are 4000 bodies in the graves, with many of them being members of the 392nd (Croatian) Infantry Division (Wehrmacht).
