Koziczyn is a village in Poland, located in the Masovian Voivodeship, within Ciechanów County, in the gmina (administrative district) of Regimin. The first historical records of the settlement date back to 1396, when it was a ducal estate. By the 16th century, Koziczyn had become a noble village, and its social and cultural heritage was enriched by figures such as Bolesław Biegas, a renowned artist born in Koziczyn in 1877.
One of the village’s notable landmarks is its modern palace, built in 1890 in the Neo-Renaissance style. Despite suffering damage during the wars, the palace remains an important part of the local landscape. Koziczyn also has a rich religious history: it was the seat of a parish church patronage, and in the 18th century, a hospital was founded by Stanisław Radzymiński.
In the 20th century, Koziczyn became an important national hub, engaging in social and educational activities, thanks in large part to the efforts of Zygmunt Choromański, who supported the local Volunteer Fire Department. After World War II, the village underwent significant demographic and administrative changes. Today, it remains primarily agricultural but also serves as a cultural center for the local community.
As of 2021, Koziczyn had a population of 199. The village includes the Parish of St. Dionysius and a parish cemetery, both of which underscore the region’s religious significance and historical heritage.
