Lennart's son Anders, governor of Estland, made unsuccessful attempts to sell the property to save his economy, and the palace was subsequently taken over by the Crown in 1696 but eventually given back to Torstensson's heir.

[2] The architect not only had to create a copy of the building on the opposite side of the square, he was also ordered to ensure the old Renaissance palace would be included into the new, a demand which reflects Gustav III's passion for Gustavus Adolphus and his era.

[1] While Sophia Albertina, before her death in 1829, had the palace bequeathed to the Swedish heir presumptive (i.e. the hereditary prince), it was during the ensuing decades used by court officials and as offices for various authorities, a faith which would eventually prevail.

Before Oscar II became king in 1872, he and his wife Sofia used the palace as their residence, where their son, Gustav V, and other members of the royal family, including Prince Eugén, spent parts of their childhood.

East of the square, a new opera building was erected in 1782 (demolished in 1892) and the façade on the western side was designed as a copy of the former, echoing its pilasters and the columns of the accentuated central portion.

Some of the grand visions Tessin developed were carried through with the construction of the bridge Norrbro, even though the centrepiece in his plans, a royal church on the northern side of the square, remained a dream.

The wall frameworks by Louis Masreliez featuring nymphs, cupids, and muses, were once surrounding the embroideries produced by the princess and her court, but are today replaced by wallpapers with painted flowers.

In the room are two 17th century desks by Gottlieb Iwerson and Georg Haupt, the latter featuring an ornamental inkstand originally intended to be a gift to Marie Antoinette.

Many of the furnitures in the room date back the Princess' era and are still found on their original locations, as are the painting Belshazzar's Banquet and the Rococo cabinet featuring with the Swedish Coat of Arms in bronze.
