The Church building's design is by Adolphus Druiding. Work began on this grandiose structure in the spring of 1893 and was completed by 1898. The building has a façade of rusticated stone in the High Renaissance style which dictated the use of classical elements such as columns, capitals and arches. At the very top is a monumental pediment decorated with the coat of arms of Poland's failed January Uprising, under which is found the inscription "Boże Zbaw Polskę" (God Save Poland in Polish). Just below this on the entablature, is the Latin inscription "Ad maiorem Dei Gloriam", a text which proclaims that this building is for the Greater Glory of God, a Jesuit motto popular in many churches built around the start of the 20th century. Three Romanesque portals set in receding arches lead into the interior. Like St. Michael's, the entrance is flanked by two asymmetrical towers topped with copper cupolas, and in height, styled after St. Mary's Basilica in Kraków. The whole structure is long and wide and can easily accommodate 2,000 people.
