In 1840, for the purposes of the Tsar family, who resided in the Royal Łazienki, a small, cosy room was created in the Small Gallery. It was named the Balcony Room owing to its direct access to the southern balcony – through the tall balcony door. The balustrade, visible through the windows, was installed in the 1780s according to the design by Stanisław August himself. The walls of this room are lined with fabric. At present, the interior is decorated with portraits of personalities living in two periods: the 18th century – Stanislavian times, and the 19th century, when the Palace became the property of the House of Romanov. Attention is drawn by the beautiful portrait of Empress Catherine II, most likely by Giovanni Battista Lampi, an outstanding portrait artist, popular among the European aristocracy in the last quarter of the 18th century. In the Balcony Room, we may also admire the portrait of Anna (Anetka) Tyszkiewiczówna, daughter of Stanisław August’s niece, who was known for her sharp sense of humour. Another personality from the entourage of the last king of the Republic whose portrait can be found in the Balcony Room is Augustyn Deboli, Polish ambassador to Saint Petersburg.

The room’s interior has been equipped with pieces of furniture from the 18th century, in the style of Louis XV (commode), and Louis XVI (armchairs, inlaid wooden table). Small figurines standing in this room are also interesting: A Bathing Woman by Étienne Maurice Falconet, as well as Malabar Man and Malabar Woman – executed in the oriental style in the Royal Porcelain Manufactory in Messen.
