 As with many of the buildings that were reconstructed after the Deluge, Tylman designed the church in Palladian style.Between 1718 and 1721 the trompe-l'œil altars of St. Casimir and Virgin Mary were sponsored by Michał Kazimierz Radziwiłł, voivode of Vilnius.In 1718 the church furnishing was completed with a profuse late baroque pulpit in the shape of a flower and between 1745 and 1748 with a rococo organ.
