The Pilica parish became part of the Kielce diocese only on December 28, 1882, having already had approximately 600 years of history. The first source information about the church in Pilica and parish life comes from 1325, and is provided in the files of the Apostolic Chamber. This publication is the first attempt at a synthetic approach to religious life in this area, prepared on the basis of the author's extensive work entitled "Pilica - Historical Study" contained in the typescript from 1979. In the oldest visitation documents of the Krakow diocese about the parish in Pilica and its church we have no record. Only from the visit carried out in November 1598 we learn that outside the city, on a mountain in Stara Pilica, there is a wooden church of St. Peter, built twenty years ago to replace an old church that had fallen apart over time. This particular church, demolished around 1575, was the first parish church in Pilica after the parish was established there. The time of its creation should be referred to the 11th or 12th century. The Pilica parish, located in the Kraków province and the Lelów castellany, belonged to the Kraków diocese from the beginning of its existence, but until 1334 it was part of the Irzadze deanery, and then it was incorporated into the Lelów deanery. The biggest breakthrough in the history of the settlement and its religious life occurred in the 14th and 15th centuries, when in 1393 Pilica received city rights. The following years brought dynamic development of the parish, the establishment of new churches and a monastery, the introduction of post-Tridentine reforms and new socio-religious institutions. It was the Swedish army in the 17th and 18th centuries that brought severe devastation to the town and surrounding villages.
