The Pauline monastery of All Saints in Streza was founded in 1374 by the endowment of magistrate Ivan Bissen. In less than two centuries, monastery in Streza became one of the most influential monasteries in this part of the late medieval territory of Slavonia. Due to the increasing Ottoman incursions at the beginning of 16th century, Pauline monks have abandoned the monastery in Streza and found refuge in Lepoglava. Abandoned monastery became the main source of building material for the local population, which abetted its further degradation. During six seasons of archaeological research (2006–2011) the external dimensions of the monastery complex were confirmed, as well as the layout of the Church of All Saints, constructed in compliance with the preferences of Pauline Order for building sacral edifices. Nave of the monastery church was entirely examined during works in 2008, 2009, and 2011. In total, 77 graves, which can be dated in the period between the founding (taqn) and the abandonment of the monastery (tpqn), have been excavated. Exception amongst the examined graves in the nave of the monastery church is grave 071, buried in a walled tomb located in the north part of the fourth bay. Social status of the deceased, apart from the location and the construction of the tomb, was evident from the lead bulla of Pope Boniface IX (1389–1404) found on the left side of his chest.
