In 1983, the castle was bought by the McTaggart family and they still own it today.
While not run as a hotel, the property is available as a wedding venue – its popularity undoubtedly boosted by its appearance in The Traitors.
Last year Loukas Tsarmaklis, a director of Ardross Castle Enterprises, told The Press and Journal, external they “try to keep a low profile… but there is no chance now.”
“This has put us on the map and helped local B&Bs, tradesmen, taxi drivers, cleaners. It was a big operation for this part of the world,” he added.

Ross and Cromarty Heritage Society said views of its page about Ardross increased significantly last January because of the US show.

On the day episode one of the second series of the UK show aired earlier this month, searches increased by 4,500% compared to the average volume over the last five years.
