Also know as the 'Church on the Rock,' this gorgeous riverside sanctuary is one of the oldest, most legendary and important religious sites in Poland. It was here - or rather at the Romanesque church that once stood here - that the Bishop of Kraków, Stanisław of Szczepanów, was beheaded on the order of King Bolesław II; soon after, the king was exiled and the royal family fell under a curse. To appease the spirit of the wronged bishop, the family rebuilt this church and made annual pilgrimages here from Wawel to atone for the murder - a tradition which continues to this day each May 8th. Since 1472 a monastic order of Pauline Fathers has resided at Skałka, and in the 18th century the church received a Baroque refurb, which endures to this day. Stanisław was canonised in 1253, becoming the patron saint not only of Kraków, but of Poland. Inside an altar marks the place where he was killed and includes a piece of wood upon which he is said to have been quartered. The pool where his remains were thrown still stands outside the church, elegantly adorned with a sculpture of the saint from the 17th century, and the waters bubbling out the fountain there are said to have healing properties.
