Antoniówka is a village in the Łódź Voivodeship, located in the Opoczno County, within the administrative district of Sławno, in the area of the Spała Landscape Park. The village lies on the Słomianka River, a right tributary of the Pilica, and is well-connected thanks to the provincial road No. 713 and the Koluszki–Skarżysko-Kamienna railway line. The population of Antoniówka is 378, with a majority of women. The village features a Community Hall, a grocery store, a mineral plaster production plant, and an agritourism farm offering accommodation. Antoniówka is also a venue for recurring events such as summer cinema screenings and beach volleyball tournaments, which promote local culture. Historically, in 1619, the village belonged to the Sandomierz Voivodeship, and in the 19th century, it became a distinct settlement. During World War I, the front line passed through Antoniówka, which was associated with the presence of Russian and German soldiers. Cholera crosses preserved in the village serve as a reminder of the epidemic at the end of the 19th century, which decimated the local community. Architecturally, Antoniówka features wooden cottages from the late 19th century, as well as an old stone railway bridge dating back to 1885. The village's folklore is diverse, influenced by both Lesser Poland and Masovia, as evidenced by local customs and folk songs. The Rural Housewives' Circle actively promotes and cultivates Opoczno traditions. An interesting fact is that in 1986, scenes for the film "Prywatne śledztwo" (Private Investigation), directed by Wojciech Wójcik and starring Roman Wilhelm, were filmed in Antoniówka. In 1944, the village became part of the Łódź Voivodeship, having previously belonged to various administrative units. The area of Antoniówka is rich in history, and its local folklore and architecture reflect the cultural traditions of the region that have endured to this day.
