The Jadow Deanery, part of the Warsaw-Praga Diocese, was established in 1918 and comprises parishes separated from the Radzymin Deanery. The current dean is the parish priest of the Church of St. James the Apostle in Jadów. The history of the deanery is enriched by the figure of Blessed Father Michał Woźniak, who served as dean from 1920 to 1923 and was beatified in 1999 as one of the 108 Martyrs of World War II. The Jadow Deanery is characterized by its sacral architecture, reflecting local traditions and building styles that may incorporate elements from various historical periods. Culturally, the deanery plays a significant role in the region, uniting residents through religious and social activities. Furthermore, the history of the deanery is an important part of the cultural heritage, where parishes serve not only as places of worship but also as social centers. Interestingly, the role of dean has been associated with various parishes over the years, influencing the development and integration of local communities. It is also worth noting that the deanery reflects historical and political changes in Poland, making it an important reference point for researchers and residents of the region.
