In 1705, Baroque composer Georg Philipp Telemann became Kapellmeister to Erdmann II of Promnitz, privy Councillor to Augustus II the Strong, elector of Saxony and king of Poland, and spent considerable time at the Pszczyna Palace when the latter's court summered there.

During the First World War, the palace, then in the Prussian Province of Silesia, at times hosted William II, German Emperor, and there are pictures on display of him together with Generals such as Erich Ludendorff and Paul von Hindenburg discussing military operations.

Following the joint German-Soviet invasion of Poland in September 1939 at the start of World War II, the complex was occupied by the Wehrmacht.

The Royal Apartments, also referred to as the Apartamenty Cesarskie, are the rooms in which the rulers of the principality and the German Kaiser resided.

When ascending the Grand Staircase, designed by Destailleur, the apartments of Princess Mary Theresa Olivia Cornwallis-West von Pless are reached.

The princess, called Daisy, lived there from 1891, when she married Prince Hans Heinrich XV and left her native England, until her death in 1943.
