One of the most famous events in the history of Catholic-Orthodox relations in medieval Poland is the episode from 1412. King Władysław II Jagiełło received the Orthodox cathedral at the castle in Przemyśl and handed it over to Catholics. The decision had an important political background related to the Polish-Teutonic conflict. Deprived of the main church of the diocese, the Orthodox bishop of Przemyśl had to find another Orthodox church for a temporary cathedral. Historiography maintains the thesis that after 1412 it was the Orthodox church at the Basilian monastery of the Dormition of the Theotokos in Wilcze near Przemyśl. However, there are no sources saying that the cathedral was established there, or data about the period of its functioning in Wilcze. The authors of this paper have assumed that the bishop established the cathedral in one of his residences outside of Przemyśl. It was either a monastery in Wilcze near Przemyśl or a monastery in Spas near Stary Sambor. However, in 1412 there was no Basilian monastery in Wilcze, dedicated to the Dormition of the Theotokos. The earliest information about it comes only from 1608. However, as early as 1378 in Wilcze there was a Basilian male monastery dedicated to Saint Spas (the Saviour). Therefore, information about the situation after 1412 applies to the church at the monastery. Orthodox bishops of Przemyśl returned to Przemyśl in the second half of the 15 th century. Their seat was a new wooden cathedral used until 1535
