The Grudziądz I Deanery is one of 24 deaneries in the Diocese of Toruń, with a rich history dating back to the times when it belonged to the Diocese of Chełmno, based in Pelplin. Territorial structural changes occurred in 1992 when the deanery came under the jurisdiction of the Diocese of Toruń, and a significant reorganization took place at the turn of 2001 and 2002. Architecturally, the deanery stands out for the diversity of styles in its constructed temples, which reflect the development of the local community and changes in the religious life of its inhabitants. Many of the parish churches have historical significance, and some of them are recognized as monuments, which in turn highlights their cultural value.

The parishes in the Grudziądz I Deanery serve as meeting places not only in a spiritual context but also a cultural one, organizing various events that integrate residents and nurture regional customs.
