Clava Cairns Stone Circle North stands as one of Scotland's most mystical prehistoric sites and serves as the real-world inspiration for Outlander's fictional Craigh na Dun stone circle. This Bronze Age monument, dating back 4,000 years, consists of standing stones and burial cairns that create an atmosphere of ancient Scottish spiritual power. While the actual time-travel scenes were filmed elsewhere using a constructed set, Clava Cairns provides the authentic archaeological foundation that inspired Diana Gabaldon's creation of the mystical stone circle central to Claire's journey through time. The site's astronomical alignments and ritual significance demonstrate the sophisticated understanding of time and celestial movements possessed by ancient Scots, themes that resonate throughout Outlander's exploration of past and present connections. The North Circle's preserved stone arrangements and ceremonial atmosphere offer visitors the opportunity to experience the genuine spiritual energy of Scotland's ancient sacred sites that form the mystical backbone of the entire Outlander story.
