The Holy Trinity Church in Iwanowice Włościańskie is a wooden temple located in the Lesser Poland Voivodeship, included on the Wooden Architecture Route. It was built in 1745 on the site of an earlier Gothic church from 1408. The history of the church is closely linked to the Polish Brethren and their activities in the 16th century, as well as to the re-Catholicization of the village after the Dłuski family converted to Catholicism in the 17th century. The temple, founded by August Aleksander Czartoryski, is built in a log structure with vertically boarded walls and a steep roof covered with sheet metal. It is characterized by two towers with a post-and-frame structure, topped with cupola spires. The interior is decorated with false vaults and several historic Gothic sculptures, including a statue of Saint Christopher from the years 1480–1490 and sculptures from the first half of the 16th century. The church has been renovated multiple times, including in the 19th century and the 1970s. The building also features three altars with paintings in the Mannerist style, including a Gothic painting of the Madonna and Child and a late Gothic crucifix from the 16th century. The church is a valuable element of the region's cultural heritage and has been entered into the register of immovable monuments of the Lesser Poland Voivodeship.
