The Traitors is filmed at Ardross Castle in Scotland, near Alness in Ross- shire, Highlands. Ardross Castle serves as the main location for both the UK and US versions of the show, providing the castle interiors and surrounding grounds used for the competition and social dynamics. The property is a 19th- century Scottish Baronial style castle with about 100 acres of parkland and gardens, set along the River Alness, which creates the distinctive, dramatic backdrop seen on screen. If you’re hoping to visit, note that while Ardross Castle is a real filming site, access for occasional tours or stays is typically limited and may require special arrangements or events.
