The walls are decorated with painted wall panels in the shades of pink and green. The exhibits include: a longcase clock from 1758, made in Münster (Germany), a Baroque commode (early 18th century) with a one-door Gdańsk-style cabinet (3rd quarter of the 18th century) on it, and a table (from the Franciscan Nunnery in Cracow), a secretary desk with an oblique hinged desktop and a bronze statuette of Jean-Jacques Rousseau.

The Antechamber leads to an apartment located on the ground floor of the west wing, consisting of three rooms arranged in an enfilade.
