There has been a castle on the site of current Balnagown Castle since the 14th century, although the present building was remodelled in the 18th and 19th centuries. Balnagown is the ancestral home of the Chiefs of Clan Ross.
In the early 14th century, a castle was begun at Balnagown by Hugh, Mormaer (Earl) of Ross. Hugh was husband of Maud, sister of King Robert the Bruce, although after Hugh's death in 1333, his family lost royal favour and their lands were forfeit. Balnagown was acquired by a stepson of Hugh in 1375 who expanded the estate, a process which continued over the following centuries. In 1585 Alexander Ross, 9th laird of Balnagown, was outlawed, as was his son George.
During the Wars of the Three Kingdoms, David Ross, 12th of Balnagown, fought for King Charles II at the Battle of Worcester (1651), although he was captured and died in the Tower of London. The 13th laird, another David, married Anne, daughter of James Stuart, 4th Earl of Moray, in 1666. David and Anne rebuilt Balnagown, as attested by a datestone of 1672 on the castle, although they left no heir, and the estate passed to the Rosses of Halkhead in 1711.
In 1754 Balnagown passed to another branch of the family, when it was inherited by Admiral Sir John Lockhart-Ross, 6th Baronet. The admiral spent much time and money improving the Balnagown estate. His son and heir Sir Charles Lockhart-Ross consulted James Gillespie Graham on Gothic Revival style alterations to the castle, and Italian gardens were laid out. Sir Charles Ross, 9th Baronet, inherited in 1911. He continued the tradition of agricultural improvement, introducing the silo and the combine harvester to the estate. He also invented the Ross rifle, which he had manufactured in Canada. To prevent the seizure of Balnagown by the Inland Revenue, Ross had the estate declared a ward of the court of Delaware, and he was subsequently unable to return to Britain for fear of imprisonment. From his death in 1942, until 1972, the castle was unoccupied and became dilapidated. In 1972, it was purchased by Mohamed Al-Fayed, who began restoration of the house and grounds.

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.
