The Church of the Transfiguration of the Lord in Wasilków is a neo-baroque structure from the 19th century, built between 1880 and 1883 according to the design of Romuald Lenczewski. It belongs to the Parish of the Transfiguration of the Lord, in the Wasilków deanery of the Białystok archdiocese, and is located in the town of Wasilków in the Podlaskie Voivodeship, within the Białystok County. The church draws inspiration from Romanesque and Gothic styles, which is evident in its single-nave structure and the bell tower that dominates the entire building. During World War II, the church suffered significant damage, but it was rebuilt in 1944, highlighting the determination of the local community and the importance of this site in the region. Until 1961, the church served as a parish church, then became a subsidiary church, only to regain its parish status in 1983. The interior of the church is adorned with rich furnishings, including 14 Stations of the Cross paintings, a carved confessional, and a baptismal font from 1860, which predates the church itself. Interestingly, despite historical turmoil, the church has retained its cultural significance, serving as a vital element of local identity and tradition.
