The origins of the Basilian monastery of St Onufry in Ławrów, located in the eparchy of Przemyśl, probably date back to the late 12th century. In the 17th century the monastery remained under the control of the Orthodox bishops. In 1659, by the decision of the Orthodox Bishop of Przemyśl, Antoni Winnicki, the monastery was organised according to the rules of the Maniów Monastery. Ławrów maintained special relations with the Winnicki family, to which three eparchs of Przemyśl belonged. After the diocese of Przemyśl accepted the union with the Latin Church in 1691, the monastery came under the jurisdiction of the Uniate bishop. Only in 1739 the monastery was transferred to the Basilian Congregation of the Protection of the Blessed Virgin Mary, an association of monasteries on the territory of Russia. Between 1743 and 1780 the Ławrów Monastery was attached to the Province of the Protection of the Blessed Virgin Mary, known as the Polish or Royal Province. In 1780 the monastery became part of the Province of the Redeemer, known as the Galician Province. The residences in Bilin and Wysock Wyżny were then dependent on the monastery. The Ławrów monastery differed from other monasteries in the Polish province in its equipment and the number of monks. In the second half of the 18th century there were between 9 and 29 monks. The superiors of the monastery belonged to the Basilian intellectual elite and served as protoihumens in the Province of the Protection of the Blessed Virgin Mary. The Ławrów monks developed pastoral and educational activities. From the 1840s, monastic studies in rhetoric, philosophy and theology were organised in the monastery. Thanks to the opening of a boarding school for lay youth, the lower nobility was also educated here. The Ławrów Basilians also accepted the sons of the bourgeoisie. Educational activities were supported by the monastery library, one of the largest Basilian libraries in the province.
