Château de Ternay was built by the Aviau de Ternay family. In twelfth-century foundations, the present château is the result of building campaigns from the fifteenth to the seventeenth centuries.
Charles Louis d'Arsac, Chevalier de Ternay (1722–1780), styled Chevalier de Ternay, born at the château, escorted the French troops of Rochambeau to join the American Revolution. Felled by a fever, he is buried in Trinity churchyard, Newport, Rhode Island.
Still the seat of the Comte and Comtesse de Ternay, today the château is open for tours and overnight guests.
Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
