Budinjak is located in the central area of the Žumberak Mountains at a height of 740 m above sea level, about 50 km west of Zagreb. Near the village a plateau is located where there is a large necropolis burial mound from the early Iron Age. These findings represent the remains of the Hallstatt culture and show the economic wealth and strength of this Iron Age population to be one of the richest Iron Age findings in the southeastern area.
