The Rosslyn Frequency: Uncovering the Hidden World of the Knights Templar 2009

Directed by Philip Gardiner

Author Brian Allan is your guide in this documentary that examines provocative evidence that Rosslyn Chapel -- the church in Scotland featured prominently in Dan Brown's novel The Da Vinci Code -- harbors a heretofore undisclosed secret. Unveiling the existence of a puzzling frequency within the chapel walls, Allan then explores the implications of the strange phenomenon, including the possibility that it opens a doorway to another reality.
