The Brzeźnio Commune, located in the Sieradz County of the Łódź Voivodeship, plays a key role in the region, with its administrative seat in the central village of Brzeźnio. Known for its flat, sculpted terrain, the commune focuses on agriculture and food production, a result of its dominant agricultural land use (70% of its area). The commune covers an area of 128.73 km², which constitutes 8.63% of the county's total area.
Demographically, the commune had a population of 6,336 in 2017, reflecting a decrease compared to 2008. Brzeźnio Commune stands out not only for its natural assets but also for its historical richness, exemplified by its preserved monumental trees. In Kliczków Mały and Kliczków Wielki, several impressive oaks and linden trees grow, with the thickest oak having a circumference of 772 cm and an estimated age of about 400 years.
Another point of interest is the Próba Reservoir, located near Brzeźnio, which offers recreational opportunities for both residents and tourists. The commune encompasses numerous village administrative units, such as Barczew, Dębołęka, and Rybnik, and borders communes like Brąszewice, Burzenin, Sieradz, Wróblew, and Złoczew, further highlighting its strategic location in the region.
Despite its relatively small size, Brzeźnio Commune is rich in natural resources, cultural traditions, and natural beauty, making it an interesting place to live and visit.
