The Parish of the Holy Apostles Peter and Paul in Krępa Kościelna boasts a rich history dating back to the 14th century, when a local parish priest, Maciej of Krępa, was first mentioned. In the 1440s, the heirs of the village were Piotr and Oswald of the Dębno coat of arms. The first wooden church, built in 1326, was replaced by another in the 15th century, which served as a filial church of the Lipsko parish. After a period of dissolution, the parish was re-established in 1679 thanks to the heir Denhoff. Between 1774 and 1778, another wooden church was built, funded by Konstancja of the Sanguszko family, and consecrated in 1778.
The current church, renowned for its Vistula-style Neo-Gothic architecture and built of red brick, was constructed between 1911 and 1930 based on a design by architect Rudolf Meyer. The new church was blessed in 1930 and consecrated in 1961. Its interior features the altar of St. Tekla, transferred from the previous wooden church. The church is listed in the register of historical monuments and enjoys legal protection status. The parish covers a broad area, including localities such as Krępa Górna, Huta, Jawor Solecki, and Wiśniówek Mały. It is also known for one of its alumni, Bishop Stanisław Sygnet.
Over the centuries, the parish has been led by many pastors, including Fr. Feliks Spychała, who served for 34 years. Since 2019, the parish priest has been Fr. Henryk Kowalczyk. The church not only stands as an architectural treasure but also serves as a significant cultural and historical landmark for the local community.
