Donnersmarck mausoleum in Świerklaniec, Neo-Gothic mausoleum in Świerklaniec, Poland.

The Donnersmarck mausoleum in Świerklaniec is a brick and sandstone structure on a Greek cross plan, built 1903–1905 to Julius Carl Raschdorff's design. It has two levels: sarcophagi above and concrete burial chambers below. A high roof is topped by a hammered-copper angel, and the interior has star and rib vaults. An L-shaped open cloister links it to the church.

The mausoleum was built in 1903–1905 to a design by Julius Carl Raschdorff, architect of Berlin Cathedral, and linked to the church by an L-shaped open cloister. After 1945 it was looted and partly devastated, and the burial chambers were opened. The church and mausoleum were entered in the monument register on 3 October 1983 (A/1317/83) and re-entered on 4 August 2021 (A/865/2021).

The church is a filial church of the Parish of Christ the King in Świerklaniec, dedicated to the Good Shepherd after its 1983 consecration by Bishop Herbert Bednorz; the name of Our Lady of Częstochowa is also used. Its 1998 windows hold stained glass by Werner Lubos, made in the workshop of Anna and Ireneusz Zarzycki, with fragments of the Lord's Prayer in various languages.

The mausoleum sits within park grounds accessible via marked pathways. Visitors should dress appropriately when visiting during active church services.

This building is one of the few remaining structures from the original Donnersmarck residential complex that survived the post-war period. Its preservation makes it a rare witness to the former prosperity of the area.
