About This Structure

Five pyramid-shaped stone constructs arranged on Lot 15, originally dubbed "Pirate Piles" by the late Fred Nolan. The cairns point toward the swamp. In Season 11, archaeoastronomer Professor Adriano Gaspani analyzed the positioning of the cairns and determined they were built in alignment with the stars, sun, and the moon's position in the night sky. By calculating how long ago those alignments were exact, Gaspani dated their construction to approximately 1250 AD - the same period he attributes to Nolan's Cross (dated 1200 AD). Gaspani concluded that both monuments were built by the same group and attributed the work to the Knights Templar. Metal detecting near the cairns by Gary Drayton recovered a decorated lead strip suspected to be medieval. Analysis revealed similarities to a twisted lead artifact from Lot 13 with Scandinavian origins, raising the possibility of Viking involvement alongside the Templars.
