20 Roubles Nesvizh

Nesvizh Castle, the subject of this issue, served as the ancestral seat of the Radziwiłł family for over four centuries — one of the most powerful noble dynasties in the Polish-Lithuanian Commonwealth. The castle's archives and library were looted repeatedly, by Swedish forces in the early 18th century and again by Napoleonic troops in 1812. What survived was largely dispersed after the Russian imperial government confiscated the estate following the 1939 Soviet annexation of western Belarus.

UNESCO inscribed Nesvizh on its World Heritage List in 2005, alongside Mir Castle, under a single joint nomination — an unusual dual-site designation driven by their shared Radziwiłł provenance.
