 During that same period, several filial monasteries were also established, the most noteworthy being the filial monastery in Warsaw, which has remained in operation to this day.In 1796, Prussian authorities confiscated the holdings of the monastery after the third Partition of Poland.Nevertheless, it continued to play an important role in the religious life of the region as the seat of a newly created eparchy for those devout Ruthenians under Prussian rule, starting in 1797 and lasting until it fell under Russian rule after the Treaties of Tilsit in 1807.
