In modern times, the Uniate deanery of Gródek was the easternmost part of the Przemyśl diocese. Located in the basin of Wereszyca and the Dniester, it bordered in the east with the diocese of Lviv-Halitsko-Kamenets, in the south with the deanery of Mokrzany, and in the west and north with the deaneries of Jaworów and Sądowo. Its history dates back to at least the 16th century, when Gródek was the seat of a well-developed deanery. The Uniate community dominated the region, constituting 64.6% of its population. The deanery had 51 parishes covering 59 towns in an area of 784.3 km2. The right of patronage over 31 parishes (61%) of the deanery belonged to the nobility, 36% to church institutions, and 17 (33%) to royal institutions. The latter group therefore constituted a significant part of the deanery, mainly in its north, occupying approximately 328.7 km2, i.e. over 2/5 of its total area. Among the royal settlements in which there were Uniate parishes, one belonged to the Janów starosty, one to the Jaworów starosty, and fifteen to the Gródek starosty. The richest of these seventeen were three parishes in Gródek. The other parishes were poorer. The Uniate parishes of royal patronage in the Gródek deanery were one of many places of intersection of Western and Eastern cultures in Poland, constituting a typical area of coexistence of two rites of the same denomination in the Polish-Russian mixed space.
