The first stone church of Holy Trinity with a belfry was built by Konstanty Ostrogski in 1514 as a token of appreciation for a victory of Polish-Lithuanian forces over Muscovite troops near Orsha (Battle of Orsha). The original church was built in Gothic style. In first half of the 17th century to the church were added three chapels. In 1609 on an edict of the King of Poland Sigismund III Vasa the church and monastery was transferred to the Basialian Order.
