The church comes from the end of the 19th century, but the first sanctuary was built in this place at the end of the 14th century. The Neo-Gothic walls are decorated with scarps and an arcaded crowning cornice. Inside there is a Classicistic main altar from the beginning of the 19th century with a miraculous picture of the Mother of God with Child, which probably comes from the second half of the 15th century. The meaning of the image is emphasised by the silver crowns on the Madonna’s head and the Child’s head, Mary’s gold-plated dress, and numerous votive offerings. When the settlement in Biskupin was discovered in 1933, a picture frame was made of black oak excavated at the archaeological site.

The side altars are made in Rococo style and come from the second half of the 18th century. On the altars there are Baroque crosses from the 18th century. What deserves special attention are The Early Baroque crucifix from 1632 and the Baroque statues of St. Peter and St. Paul which come from the old Dominican church in Żnin. The walls are decorated with polychromes made in 1921.

The traditional indulgence fair is celebrated in the parish on the first Sunday after 8th September. Each year, pilgrims from Gąsawa and Żnin come to the sanctuary, but in the past the pilgrims went to Wenecja from as far away as Bydgoszcz. As a result of the burning of the parish register in 1775, no records of the miracles from the past survived, but some of them can be investigated on the basis of the visitation files.

Walenty Szwajcer, the discoverer of Biskupin, was buried in the nearby cemetery.
