Take any of the dark, daunting trails off ul. Rękawka into the wooded limestone cliffs of Krzemionki to discover one of Kraków's oldest, smallest and most mysterious churches in the clearing next to Fort Benedict. The date of the present structure has been hard to determine, but the curious site certainly dates back to the 11th century and a leading theory attributes it to the Benedictine monks of Tyniec, who probably built it in reaction to the pagan practises still taking place on Lasota Hill and the area around Krakus Mound. Saved from destruction and dereliction by a local priest, the tiny, cramped interior - consisting of only a small nave and chancel with a painting of St. Benedict over the pulpit - is now open to visitors in the summer during limited hours.
