The hill of Gora near Lobor in northern Croatia is one of the region's most important multi-period archaeological sites, strategically located below Ivanščica Mountain along the ancient Roman road between Poetovio (present-day Ptuj) and Siscia (Sisak). Evidence of occupation during the Bronze and Iron Ages has been found in the form of Litzen pottery and the first earthen ramparts, which were later modified in the Urnfield period. The site flourished during the Roman period, as evidenced by tombstones and sculptural remains. From Late Antiquity onwards, Lobor developed into a major religious centre, with successive church buildings reflecting Early Christian, early medieval, Romanesque, Gothic and Baroque phases.
A magnetic survey was conducted around the Church of the Mother of God in Lobor, as well as in the open fields to the north of the church and hillfort. The magnetic data revealed the remains of several buildings and wall systems, including well-preserved structures with internal room divisions. However, near the church, modern disturbance complicates interpretation, making georadar (GPR) essential for further analysis.
