In 1386, on the eve of the baptism of Lithuania, Grand Duke of Lithuania Jogaila granted his privilege to build the parish Church of St Johns in the city of Vilnius. Construction was complete in 1426. The fire-damaged church was handed over to the Vilnius Jesuit College in 1571 by the Grand Duke of Lithuania Sigismund Augustus, which saw to its reconstruction, extending it towards the street; the church belonged to Vilnius University from 1579. A brick belfry was added in 1600–1610. In 1655, during the raiding and plunder of the Muscovite army in Vilnius, the damaged church was rebuilt once again. The Jesuits invited Johann Christoph Glaubitz, the pioneer of the Vilnius Baroque style, to Vilnius to see to the reconstruction of the church after it was damaged in the great fire of 1737. The Church of St Johns and its belfry that were rebuilt based on his design acquired a Late Baroque appearance. The eastern facade facing Pilies Street was decorated with the Chreptowicz family memorial plaque with the epitaph decorated with a skull: “In these walls of Our Lady of Loreto we leave the ashes of the aunt of the Castellan of Samogitia Anna Chreptowicz-Kryszpinowa, the wife of the Castellan of Navahrudak Römer-Chreptowicz and their daughter Marjanna Chreptowicz in the hands of the Eternal God. These words were inscribed by the order of the Castellan of Navahrudak Jan Litawor Chreptowicz in 1759, so that passers-by would sigh in recognition of his sorrow”. There were also frescoes depicting the plague epidemic that ravaged Vilnius in 1706–1710 and the Crucified Christ with the inscription “1706”. The frescoes were painted over by the tsarist government in the 19^th century, while the crucifix disappeared during the Soviet years. A marble plaque with the Chreptowicz family’s epitaph remains on the church wall to this day, above it is a small balcony with a metal fence and roof, and a few details of wall painting.
