The Church of St. John the Baptist in Warszawice is a wooden, oriented religious structure, built on a brick foundation, which constitutes a significant element of the cultural heritage of the Sobienie-Jeziory municipality in the Otwock County, Masovian Voivodeship. The foundation of the church was laid in 1736 by Dorota née Przebendowska and her husband Franciszek II Bieliński, the Grand Crown Marshal and Chełmno Voivode. Although the construction of the church was initially planned in Radwanków, it was ultimately decided to locate it in Warszawice. An important event in the history of the church was the relocation of the parish seat to Warszawice on October 1 of the same year. The church was built in a short period of time, using materials from an earlier, destroyed temple. The consecration of the church took place on September 30, 1855.
The church was entered into the register of historical monuments in 1962, which underscores its cultural and historical significance. In 2013, a renovation of the façade was carried out, contributing to the preservation of the building in good condition. Inside, there is a foundation plaque that has been entered into the list of movable monuments of Otwock County, further enriching the history of this place. The temple is an example of local wooden architecture, commonly found in Poland, and serves as valuable evidence of the region's construction traditions. From a cultural perspective, the church in Warszawice is a venue for important religious events and community gatherings, which help strengthen local traditions and communal bonds. An interesting fact is that the construction process itself, completed in a single day, highlights the determination of the founders and the importance of local communities in shaping the religious landscape of Masovia.
