1 Rouble The Radziwills' Castle. Nesvizh

Nesvizh Castle was the ancestral seat of the Radziwiłł family for over four centuries — one of the most politically powerful dynasties in the Grand Duchy of Lithuania and later the Polish-Lithuanian Commonwealth. The castle's construction began in the 1580s under Mikołaj Krzysztof "the Orphan" Radziwiłł, designed by Italian architect Giovanni Maria Bernardoni. It passed through Tsarist confiscation, Nazi occupation, and Soviet conversion into a sanatorium before Belarus began restoration work in the early 2000s, which provides the direct occasion for this issue. UNESCO World Heritage status followed in 2005, one year after this coin's release.
