'Sorrow free', a calque of Sans Souci) is a royal residence of the Danish monarch, located in Lyngby-Taarbæk Municipality, on the east side of Lyngby Kongevej, in the northern suburbs of Copenhagen.

The current house was built in 1756 by Lauritz de Thurah and later adapted and extended by Peter Meyn in the 1790s.

Sorgenfri Palace is located at the site of a medieval settlement, Mølletorp, which was owned by the Bishopric of Roskilde but confiscated by the crown during the Reformation in the 1530s.

He commissioned the architect François Dieussart to build a new summer residence at the site and renamed it Sorgenfri.

The building was refurbished by Lauritz de Thurah who also constructed new stables and a new wing for the gentlemen of the Court.

After his ascend to the throne in 1747, Frederick V gave the property to his aunt, Sophie Caroline, Dowager Princess of East Frisia.

When Crown Prince Frederik died in 1805, Sorgenfri was passed on to his son, the later King Christian VIII, who used it as a summer residence.

[5] Prince Knud and Princess Caroline-Mathilde continued to live in Kavalerfløjen until Christian X's death in 1947 and then moved into the main building.

From 1991, Count Christian of Rosenborg, a first cousin of Margrethe II, and Countess Anne Dorte lived in a detached wing of the palace called Damebygningen until they died in 2013 and 2014, respectively.

Crown Prince Frederik adapted it in the English style with winding paths and romantic garden furniture such as a well, a grotto and gazebos.
