The mannerist altars date from the turn of the C17th; the main altar has polychrome decoration imitating sculptural elements. The oldest relic is the late-gothic statue of St. Nicholas from around 1400, located in one of the side altars. Inside the church you can also see a statue of the Risen Christ, moved from the church in Chechło, and the wooden baroque epitaph of Father Krzysztof Zawalski with a painting of The Crucifixion and the figure of the deceased.
