Church of St. Stanislaw Kostka is one of Krakow's youngest churches was built in the 1930s. After the war, it's parish was the largest in Krakow (13.000). Its position as the primary church across the river in the largely residential disctrict of Debniki ensures that it remains of one the city's largest today.
In fact, Karol Wojtyla (John Paul II) was a parish member while he lived nearby at Tyniecka str., 10 in 1938-1944. Exactly in the Church of St. Stanislaw Kostka he heard mass every day when he started to understand his priestly vocation which would eventually provide him to the papacy.
This church is a little bit different from the others in terms of architecture. I would say that this Church has for the most part, cubic shape. If you pass near, be sure to take a few photos - you wont see a lot of such churches.
