The Great Assembly Hall
During the reign of Stanislaus Augustus this room was used for state ceremonies. The courtiers met in this room, and it was here that banquets, balls and concerts were held and theatrical performances staged.The room was decorated and furnished in the years 1777-81 according to a design by the architects Domenico Merlini and Jan Christian Kamsetzer. The statues of Apollo and Minerva and the allegories of Justice and Peace, located on either side of a medallion with a portrait of Stanislaus Augustus, were the work of the sculptors André Le Brun and Jacopo Monaldi. The huge ceiling depicts the Disentanglement of Chaos. The Hall was reconstructed in strict accordance with a pre-1939 design, making use of salvaged fragments of the stucco work. The new ceiling was reconstructed by Łucja and Józef Oźmin.
