 These brotherhoods existed before the current church was built and, therefore, the imagery is inherited from the previous church.The western (left) transept displays the painting of Blessed Virgin Mary of Mercy and two large Turkish war drums (timpano, in circumference) that were seized from the Ottomans in the Battle of Khotyn of 11 November 1673 and granted to the church by its founder Michał Kazimierz Pac.The transept ceiling has stucco reliefs from the life of Mary (with Visitation at the center) and crucifixion of Jesus.
