Assumption of Mary Church in Bielawa, Roman Catholic parish church in Bielawa, Poland

The Church of the Assumption of the Blessed Virgin Mary is a neo-Gothic, three-nave brick church on a cruciform plan, designed by Alexis Langer of Wrocław and built in 1868–1876. Its tower rises 101 metres. The interior holds fifteen ornamental stained-glass windows and nineteen glazings made in 1872–1876 by Adolph Seiler's stained-glass institute in Wrocław, and a 1913 canvas of the Assumption in the main altar.

Construction of this church took place between 1868 and 1876 under architect Alexis Langer from Wrocław, with consecration performed by Dean Adolf Rinke upon completion. The building underwent major renovations in the 1990s that addressed structural and mechanical systems.

The parish belongs to the Bielawa deanery of the Diocese of Świdnica. Its patronal feast is the Assumption of the Blessed Virgin Mary, and the main altar holds a canvas painting of the Assumption made in 1913. A 30-voice organ donated by Father Franciszek Krauze as a personal gift is still played today.

The church can be accessed through main entrances located on the western side of the building. Visitors should note that entry is typically available during worship services and special events rather than for casual daytime browsing.

The roof is covered with copper sheet metal that was installed in 1976, giving the structure a distinctive appearance that sets it apart from other religious buildings in the area. This specific material choice became an identifying feature of the building over time.
