Sanctuary of Our Lady of Grace, patron saint of Warsaw, is housed in a church under the same call, located in the Old Town. There is a revered, intronized and crowned image of the Blessed Mother of God. It is a copy of the Renaissance polychrome from the Italian city of Faenza dating back to the mid-17th century.
The church was built at the turn of the 16th and 17th centuries on the ruins of townhouses destroyed completely by fire. It combines elements characteristic of Italian and Northern European styles, including the characteristic vaulting of Lublin. A bit asymmetrically, the tower is 65 meters high.
In the basement of the church there are still multi-storey, Gothic cellars, remnants of existing houses here. In one of them the so-called. Vilnius Chapel, dedicated to the memory of teachers and students of the Jesuit gymnasium in Vilnius.
