Det Gule Palæ Palace

The Palais Det Gule Palæ, also known as the Yellow Palace, is a residence in Copenhagen, Denmark. Located in the Frederiksstaden district, right next to Amalienborg Palace, it is a pioneering example of Neoclassical architecture in the Danish capital. Its history is intertwined with the Danish Royal Family, as it once served as the residence for Prince Christian of Glücksburg, who later ascended to the throne as Christian IX, and became the birthplace of several European royals.
History+
The construction of the Yellow Palace took place between 1759 and 1764, commissioned by the timber merchant H. F. Bargum. It was designed by Nicolas-Henri Jardin in the Neoclassical style, making it an early representative of this architectural movement in Copenhagen. Originally conceived as a burgher's house, the palace was acquired by King Frederick VI in 1810 to serve as a guesthouse for royal relatives.
