On the site of the present church (Dominikonų St. 12) a Gothic single-nave church was built in the 15th century and named Holy Trinity Church. It was reconstructed after the 1748 and 1749 fires: a new presbytery and two towers were built on, and in a place of a Gothic apse a new portal was erected. The church belonged to the university; one of its deans was the university rector, Jesuit astronomer Marcin Odlanicki Poczobutt. The tsarist authorities converted it into a Russian Orthodox church in 1821, but in 1920 it was returned to the Catholics. In Soviet times the church was abandoned. On Divine Mercy Sunday, 18 April 2004 under the care of CardinalAudrys Bačkis, the church was restored, blessed, and given the title Shrine of the Divine Mercy. The church was adapted for the display of the original Image of Merciful Jesus, painted according to the vision of SaintFaustina Kowalska by artist Eugeniusz Kazimirowski in 1934. The Shrine is also decorated with two sgraffiti made by Nijolė Vilutytė: the Virgin of Mercy of the Gate of Dawn and the prayer Jesus I trust in you in eleven languages.[2][3]
