Sorgenfri Palace was built by the architect Francois Dieussart in 1705-06 for Carl Count Ahlefeldt. From 1730, this country house was owned by the royal family, and Crown Prince Frederik (V) had court architect Lauritz de Thurah build a wing for the gentlemen of the Court and a horse stable. When Frederik V became king, the palace was given to his aunt, grand duchess Sophie Caroline of East Friesland, who let de Thurah demolish the main building in 1756-57 and build a new palace. From 1791-94, the heir apparent, Frederik (VI), expanded and modernised the palace.
Frederik VII later transferred the palace to the state. In 1898, the state placed the palace at the disposal of Crown Prince Christian (X) after modern conveniences and a glassed veranda were installed. Sorgenfri Palace was Christian X and Queen Alexandrine’s preferred summer residence, and both Frederik IX and the heir presumptive, Prince Knud, were born there. Prince Knud and his wife, Princess Caroline-Mathilde, lived in the Palace until their deaths in 1976 and 1995, respectively. Sorgenfri Palace is not open to the public, but part of the park is accessible to the public.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
