In 2016 near Bornity (Braniewo district) a so far unknown stronghold was discovered. Within a small area the researchers unearthed a quarter of an early ̔Abbāsid dirham, a bronze spur with bent-in hooked extremities and a fragment of a ring of the Perm-Glazow-Duesminde type. In 2017 a preliminary small test excavation was carried out at the site. The discovered items and radiocarbon analysis of the charcoals from the rampart structure indicate that the site was in use in the last decades of the 9th century and the first quarter of the 10th century. Among the discovered artefacts the Arabic dirhams (two Hārūn ar-Rašīd’s dirhams and one al-Mahdī’s coin) deserve special attention and are discussed in detail in the article.
