SummaryThe theory that the Knights Templar, a medieval Christian military order, buried treasures such as the Holy Grail and the Ark of the Covenant on Oak Island. This is often linked to the Cathar theory and the Sinclair expedition.
OriginThe theory gained popularity in the 20th century, especially after the publication of 'Holy Blood, Holy Grail' and the TV show The Curse of Oak Island. It is also connected to claims that Prince Henry Sinclair visited Nova Scotia in 1398.
Claimed
  • The Knights Templar transported treasures to Oak Island after their disbandment.
  • The Holy Grail and the Ark of the Covenant are buried there.
  • The Money Pit was constructed by the Templars as a vault.
  • Prince Henry Sinclair, possibly a Templar, sailed to Nova Scotia in 1398.
Evidence / consensusThere is no archaeological or historical evidence for Templar presence in North America. The Sinclair voyage is disputed, and the Holy Grail and Ark are considered mythical or lost.
> OBSERVER NOTE:
A popular but unsubstantiated theory. The Templar connection relies on speculation and misinterpreted symbols.
