The Architectural, Residential and Cultural Complex of the Radziwill Family at Nesvizh is located in central Belarus. The Radziwill dynasty, who built and kept the ensemble from the 16th century until 1939, gave birth to some of the most important personalities in European history and culture. Due to their efforts, the town of Nesvizh came to exercise great influence in the sciences, arts, crafts and architecture. The complex consists of the residential castle and the mausoleum Church of Corpus Christi with their setting. The castle has ten interconnected buildings, which developed as an architectural whole around a six-sided courtyard. The palaces and church became important prototypes marking the development of architecture throughout Central Europe and Russia.
