The Parish of Saint Bartholomew the Apostle in Korytnica Łaskarzewska, established in 1326, is one of the oldest parishes in the region. The present brick parish church was built between 1919 and 1926, and its architecture reflects the local style of sacred construction. In 2017, the parish secured over 3.3 million złoty from EU funds to renovate the historic church and parish building, which allowed the restoration of the church’s historical appearance. As a result of this modernization, in 2018, the so-called organist’s house was transformed into the Museum of the Trojanów Land, which promotes local cultural heritage. The parish includes residents of numerous localities, making it an important religious center for the local community. The parish priest is Fr. Zbigniew Grzymała, who actively participates in community integration. The parish combines a rich historical legacy with modern cultural initiatives, making it a significant landmark in the region.
