Built in 1816 as a rectangular basilica, the central section of the church is higher and has a double-pitched roof, while the sides are covered by lean-to roofs. The façades used to have Gothic Revival pointed arch windows which have been replaced with tall, rectangular ones. As a result of several renovations, the church’s current appearance differs slightly from its original form. In the western section of the church, a new altar was built on the site of the old altar combined with the pulpit - a typical structure for Protestant churches. The church in Osiecznica was consecrated as a Roman Catholic temple in 1947 as a filial church of the parish in Krosno Odrzańskie.
