In 2015 and 2016, a reconnaissance study have been performed on a fortified hillfort in Lipnik, located between Sandomierz and Opatów, which had been discovered in 2015. Neither remnants of the buildings nor the presence of a cultural layer that could indicate permanent, or at least longer residence, have been found on the hillfort. Apart from the ceramics, a series of metal objects were found on the hillfort: silver beads, fragment of silver earring with ‘grape’ pendant, bronze rings, silver and bronze applications of leather straps, strap-ends, pendants and buckles from harness or saddlebags, iron and lead weights, iron arrowheads. Some of the metal artefacts have distinct analogies in Hungarian materials from 10th–11th century. Similar to the materials from a nearby settlement in Kaczyce, they indicate the possibility that groups or units of Hungarian origin that followed nomadic traditions had been staying in the vicinity of Sandomierz between the second half of 10th and the first half of 11th century. They might had been warriors serving in one of the Piast princes, captives brought by Bolesław I the Brave or merchants participating in international trade.
