The southern wing apartment of the Palace, which Antal Grassalkovich I rendered at the disposal of his friend, Count Kristóf Migazzi, Bishop of Vác and Cardinal Archbishop of Vienna, was converted into a theatre by Prince Antal Grassalkovich II between 1782 and 1785. The Palace theatre was opened earlier than the Castle Theatre that the Buda Carmelite church was converted into at the instigation of Farkas Kempelen in 1787.

Empress and Queen Elizabeth was surrounded by great respect in her life, and this deep respect evolved into a myth after her death. Much of the reason why she was that much adored originated from the role she played in the process of reconciliation. She was attributed the 'Guardian angel' role soon after coronation and her role as a link between the ruler and the ordinary people also appeared. This role then gradually transformed into a Maria-analogy by evoking the figure of Patrona Hungariae (Our Lady).

In the beginning, the suite of the Queen was characterized by her favoruite colour, violet. During the 1879 renewal, the colour of the silk wallpapers and upholstery was changed for red. The presence of the favourite colour is of special importancein this room since the furnishings here are meant to be suggestive of the Queen’s complex personality.
