St. Stanislaus Church at Skałka

Saint Michael the Archangel and Saint Stanislaus the Bishop and Martyr Basilica, also known as Skałka, which means "a small rock" in Polish, is a small outcrop in Kraków atop of which a Pauline monastery is located.

It is said to be the place where the Bishop of Kraków saint Stanislaus of Szczepanów was slain by order of Polish king Bolesław II the Bold in 1079. This action resulted in the king's exile and the eventual canonization of the slain bishop.
