The prehistoric hillfort of Obersko is characterized by relics of a fortification dating from the Final Bronze age to the Hallstatt Period. Discovered in the 2nd half of the 19th century, the first large excavation – including a section of the earthwork – was carried out in the 1st half of the 20th century. At the beginning of the 21th century, a field survey, including metal detectors, provided evidence of a settlement north-west and south-west of the fortified area. The hillfort shows an oval ground plan of 2.3 ha, and it is situated on a forested mound above the confluence of the Třebůvka and Radnička Rivers. From almost all sides, it is protected by an earthwork and ditch, best visible on the north and north-west side, where the earthwork still reaches to a height of 4–5 m, and the ditch is up to 1 m deep. The northern slope shows an additional outer earthwork. Today, modern technology, for example, aerial laser scanning, enables to distinguish features that would be invisible with the bare eye.
