From the outside it seems like a large church, but step over the threshold and you'll see a rather modest and relatively small worship hall.
The Jesuit Church, also known as Church of the Gracious Mother of God, is an ornate church within the Old Town precinct in Warsaw, Poland. The temple stands on Świętojańska Street, adjacent to St John's Cathedral, and is one of the most notable mannerist-style churches in Warsaw.
