Over the years, the Trust has raised substantial funds which have been spent on the castle including major works to stabilise the remaining building and on conducting major archaeological research which has resulted in highly important historical discoveries.
The Trust's 2006 Financial Statement[4] reported that in April of that year "the Trust acquired Noss Head Estates Limited, a privately owned company" with a generous donation from Niven Sinclair [1] and his cousin Sandi Sinclair Pershing from the US.
[5] The purchase was from Ian Sinclair and Joan Burton and comprised 35 acres of land at Noss Head, together with two houses and outbuildings.
Funds released by this sale augmented the reserves held by the Clan Sinclair Trust.
In addition, access improvements were made so that it was and is safe for members of the public to visit the castle.
