Early history When
Frederiksstaden was laid around 1748, it was envisioned as a uniform
Rococo district. All new buildings had to comply with certain guidelines stipulated by
Nicolai Eigtved, the district's master planner. After Eigtved's death in 1754 they were in principle upheld, but as fashions changed they were somewhat relaxed. In the new
cadastre of 1756, the property was listed as No. 71 I. It was by then owned by Johan Jegind. On Christian Gedde's map of St. Ann's Quarter from 1757, it was marked as No. 316. The Yellow Mansion was built from 1759 to 1764 for the merchant and slave trader
Frederik Bargum. The architect was
Nicolas-Henri Jardin and he designed it in the
Neoclassical style.
Carl Friedrich Busky, 1775–1808 Carl Friedrich Busky (1743–1808), a wealthy merchant and Prussian consul, acquired the mansion in 1775. Busky was married to Ana Sophia Gad, a daughter of shipbuilder at Fabritius & Wever's shipyard Ole Gad and his wife Maren Gad. They resided in the building with their five-year-old daughter Ana Maria Elisabet, a coachman, a male servant and two maids at the time of the 1787 census. Another daughter, Caroline Frederikke Louise Busky (1789–1872), was born in 1789. She was later married to Peter Sigvard Neergaard (1784–1858). In the new cadastre of 1806, the property was listed as No. 123. Busky owned it until his death in 1808.
Royal ownership King
Frederick VI purchased the mansion in 1810 to use it as a guest residence for relatives visiting the royal family. In 1837, King
Frederick VI handed the property over to his wife's nephew Prince Christian of Schleswig-Holstein-Sonderburg-Glücksburg, who had just arrived in Copenhagen from Germany. At this stage no one knew that he was later to become King
Christian IX as the first
Glücksburg king of Denmark. Prince Christian took up residence in the mansion and lived there with his family until 1865, when he became king and moved into Amalienborg Palace. Later, his youngest son
Prince Valdemar lived in the Yellow Palace with his family until his death in 1939 as its last royal resident. ==Architecture==
