Princess Anna I Kostczanka, belonging to the Kostka family, founded a Benedictine monastery in Jarosław in 1611. After her death in 1642, it was headed by Anna II Kostczanka, who led the monastery through a period of wars and unrest. After her death in 1656, Anna III Kostczanka took over the power. Under her rule, the monastery experienced further difficulties, including: Swedish and Hungarian invasions. After her death in 1692, the new abbess was Joanna Gołyńska, who continued her efforts to rebuild the monastery during the period of destabilization. After her death in 1725, the next abbess was one of the two granddaughters of Abbess Anna Kostczanka - Ludwika Tarłówna. Ludwika, daughter of Aleksander, castellan of Zawichost, and Joanna Kostczanka, adopted the habit in 1690 and took vows in 1691. Her reign is poorly documented, but it is known that she carried out a major renovation of the church and monastery and rebuilt the slumping slope of the monastery mountain. The next abbess chosen was Anna Mniszchówna, daughter of Józef, marshal of the Crown, and Eleonora Ogińska. She adopted the habit in 1713 and took her vows in 1715. Despite hopes for a long reign, she died on April 18, 1743, leaving no significant trace in the history of the monastery. The next in the line of succession was Katarzyna Sołtykna, the daughter of Aleksander, a groom from Bracław, and probably his second wife, Franciszka Mycielska. She accepted the habit in 1712 and made her vows in 1714. When she took over in 1743, the monastery was already in a difficult financial situation. She died on June 27, 1766. After her, Helena Łozińska, born in 1712, was chosen as her successor. There is no information about her activities as an abbess, but there are records after her death in 1781, including: about support for the Benedictine nuns from Radom for the reconstruction of the monastery. Her election took place without major problems, although the exact election records have not been preserved. The last abbess mentioned in the text was Franciszka Sołtycena, daughter of Michał Aleksander, the Sandomierz cabinetmaker, and N. Makowiecka. She adopted the habit in 1744 and took her vows in 1745. However, the following year, Emperor Joseph II ordered the dissolution of the monastery, which ultimately led to the liquidation and dispersion of the nuns. Today, more than two hundred years after the dissolution, the Jarosław monastery is coming back to life, once again inhabited by Benedictine nuns from Przemyśl. Their history and the group of abbesses now remain an object of interest, showing that despite the difficulties the order is being revived.
