Hrdlořezy, Hillfort and cultural monument near Hrdlořezy, Czech Republic.

Hrdlořezy, also called Předliška, is an undated hillfort on a spur of the Jizera Table above the right bank of the Jizera, at about 280 m elevation. A steep slope with a 56 m drop bounds it toward the river, and only the northwest side was open; there a rampart about 125 m long enclosed roughly six hectares. The partly spread rampart survives up to 3 m high and 14–18 m wide, with a faint ditch in front.

The promontory called Předliška was occupied in the Eneolithic by the Funnel Beaker and Corded Ware cultures, in the Early Bronze Age by the Věteřov culture, and later in the Urnfield, Hallstatt and early medieval periods. Surface finds include a hoard of bronze objects: a necklace of bronze beads, pins and bracelets. The surviving rampart was probably built by the Lusatian culture of the Late Bronze Age, though the fortification may have been raised or reused later; the site remains undated.

The name Předliška is used alongside Hrdlořezy for the promontory. Surface collections have yielded a hoard of bronze objects: a necklace of bronze beads, pins and bracelets, evidence of the Věteřov culture in the early Bronze Age. The site is protected as a cultural monument of the Czech Republic.

The easiest approach is from the northwest, the only side not bounded by steep slopes or ravines; the original entrance probably led from the shallow ravine to the north. The rampart survives best in sections up to 3 m high and 14–18 m wide, while the ditch in front is faint. The ground is uneven and partly overgrown.

The surviving rampart is about 125 metres long and still stands up to three metres high and 14 to 18 metres wide, though much of it has been spread by ploughing. The ditch in front is barely visible today. The wall turns east at its northern end, guarding the approach from a shallow ravine that may have held the original entrance.
