Radvilas Family (exhaustively)
 

In 1990 the first small exhibition was opened. One of the halls reminds the visitors of the owners of the Palace – the famous noble Radvilos family. 165 portraits of the family are exhibited in the hall. The portraits were engraved on the request of Mykolas Kazimieras Radvila (1702–1762) by a self-taught engraver Hirsz Leybowicz (1700–1770). In the 16th-19th centuries the eminent and influential family gave the country chancellors, vaivodes, hetmen, bishops and even a queen (Barbora Radvilaite, 1520–1551) and a cardinal (Jurgis Radvila, 1556–1600).
The Radvilos had so much wealth and collections of art that they could easily compete with the Court. Creations by Italian, Flemish, Dutch, Spanish, French, German, Austrian, Russian painters and drawers are exhibited here. In the gallery halls one can see admire pictures by Antonio Campi (died in 1591), Lodovico Carracci (1555–1619), Bartholomaeus Spranger (1546–1611), Jan Fyt (1611–1661), Cornelis Mahu (1613–1689), Cornelis van Haarlem (1652–1638), Meindert Hobbema (1638–1709), Francisco Ximenez (1598–1670), Juan Rizi (1600–1681) and other well-known and almost unknown masters of Western Europe.

Radvilas Family Portraits (exhaustively)
 

Feodalist mansions in Lithuanian Great Duchy were famous for their large picture collections. One of such picture galleries, compiled of paintings of different genres created by local and foreign artists, was in the possession in the Lithuanian nobles Radvilos, in Nesvyzius.
This collection was being formed for many years, obsolete pictures used to be substituted by new replicas. The Radvilos kin accumulated a large collection of family portraits, which was of great value for them. In the eighteenth century there were about 1000 paintings in the Nesvyzius collection. 
However, in the course of time the works of the Radvilos picture gallery were  scattered. In museums of Lithuania and Poland there has remained only a small part of those creations.In the eighteenth century Mykolas Kazimieras Radvila, called Zuvele (Small Fish), commisioned Herszek Leybowicz (1700–1770), the Nesvyzius mansion artist, to engrave the Radvilos family portraits. Thus during the period of 1745–1758 H. Leybowicz created 165 portraits. They were published by F. Wobe in the book Icones Familiae Ducalis Radvilana (Pictures of Dukes Radvilos Family). The book was republished in Petersburg 1875.
This collection of engravings is valuable, especially in the historical and iconographic aspect - it is a part of cultural heritage and a source of historic perception.
