The Church under the invocation of the Assumption of the Blessed Virgin Mary the Victorious in Lublin was built at one of the oldest communications treaties of Lublin in the years 1412-1426, on the site of the former existing Chapel of the Blessed Virgin Mary, St. Barbara and St. Sophia, consecrated by the Cracovian bishop, Piotr Wysza in the year 1396. Its inception was closely associated with the deep religious faith of the king Władysław Jagiełło in the effective assistance of God, which he experienced during the fights against the Teutonic Order. The Temple in Lublin was supposed to be a thanksgiving vote for the victory over them at Grunwald and Tannenberg on 15 July 1410. At the same time it was also the first monument in Poland commemorating it.

This event is documented by 3 commemorative plaques, which are located in the chapel of the Blessed Mary and St. Juda-Thaddeus, under the stucco bust of the King - the founder, in a semi-circular niche above the main entrance to the church and in the niche imitating the entrance on the pediment of the church.

Next to the Church, also on initiative of the king, there was built a Bridgettines' monastery ( for nuns and monks), who were brought from Gdansk. It was believed for that the defeat of the Teutonic Order had already been predicted by St. Bridget in her earlier writings. Władysław Jagiełło himself believed that he himself had been a prophesied Commander, who was to punish the Order for the crimes they committed.

According to tradition, the principles of the functioning of the Order of the Most Holy Saviour (so-called Brigids) were revealed to St. Bridget by the Christ himself. Its original feature was that in those monasteries religious sisters and monks lived side by side separated by the monastic wall, while the monastery was in charge of the Abbyss. However, the Tridentine reforms have eliminated the male division (the end of the 16th century). The convent in Lublin was one of the first Brigidian monasteries in Poland, beside existing ones in Gdańsk and Elblag. In the opposite however to the two remaining, which has struggled with financial or organizational problems, the Order in Lublin developed under favorable conditions and for many years was the only female convent on the east of the Vistula River.

On the west wall of the northern chapel in the conch-shaped niche there is a bust of the monarch, King Władysław Jagiełło from the year 1910. On the head of the King there is a royal crown, there is a cross around his neck, a robe tied on his right shoulder. The background of the niche depicts an oak's leaf relief. Beneath the niche there is an inscriptive brown marble plaque with a gold epigraph:
