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.

The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
