St. Nicholas Church in Wilcza is a historic wooden temple located in the Silesian Voivodeship, serving as a parish church in the Knurów deanery of the Katowice Archdiocese. Built at the turn of the 17th and 18th centuries, it is an example of traditional wooden architecture, distinguished by its oriented log structure using oak, pine, and spruce wood. The church features a tripartite layout, with a three-sided closed presbytery and a wider nave covered by a flat ceiling. Inside, Baroque furnishings can be found, including a 17th-century main altar adorned with a painting of St. Nicholas, as well as late-Baroque side altars depicting the Holy Family and Our Lady of the Rosary. An interesting feature is the votive painting of the Frydek Mother of God from 1709, which places the church within the context of the region's Marian devotion. It is also worth noting that the church has witnessed political and religious changes in Upper Silesia, being subject to various influences, which is reflected in its history. The first church in the village was built in 1480 but was destroyed during the Thirty Years' War. The current temple was constructed in 1755 by carpenter Jakub Sedlaczek from Gliwice on the initiative of Father Józef Wran. Surrounding the church is a cemetery, and within the fence, visitors can see a modern Lourdes Grotto and a statue of the Passion of Christ from 1883. The church is also situated on the Silesian Voivodeship Wooden Architecture Trail and near tourist routes, making it an attractive destination for tourists interested in both the religious and cultural history of the region. The church was renovated in 1961 and again between 2007 and 2012, demonstrating a commitment to preserving this unique site for future generations.
