Church of Immaculate Conception Of Blessed Mary, Roman Catholic church in Niemcza, Poland.

The Church of the Immaculate Conception of the Blessed Virgin Mary in Niemcza is a Neo-Romanesque hall church built in 1864–1865 to designs by Friedrich August Stüler. It measures 40 m long and 20 m wide, with a 60 m tower. The interior has a beamed ceiling, wooden galleries, three 18th-century Baroque altars and a pulpit from the former castle church.

This church was built in the 1800s by combining medieval architectural traditions with construction techniques of that era. It was officially recognized as a protected monument in 2014 in the Lower Silesian region.

The three Baroque altars and the pulpit came from the castle church, which no longer exists; the remaining altars and the Neo-Gothic baptismal font were made in the second half of the 19th century. From 1530 to 1945 the church belonged to Protestants, and since 1947 it has served as a Catholic parish church.

The church stands in Niemcza, in the Dzierżoniów district of Lower Silesia, and is an active Roman Catholic parish church, so visits are best arranged around Mass times rather than assumed. The building is 40 metres long, 20 metres wide and its tower rises 60 metres, making it easy to spot from the surrounding streets. It was entered in the state register of monuments on 30 September 2014 under number A/5939.

The neo-Romanesque church was designed by Friedrich August Stüler, the architect behind Berlin's Neues Museum. King Frederick William IV rejected Alexis Langer's competing neo-Gothic plans. The building was entered in the state register of monuments on 30 September 2014 under number A/5939.
