Excellent post, ty.

Many stories about the location/disposition of the Arc of the Covenant. Some say that that was the real reason why the Templars were in Jerusalem for as long as they were, and that they spirited it out of Jerusalem and to France, and then to Scotland, and then eventually to the USA, etc. Still others say that it was brought up the Nile to Ethiopia and is still there today.

Lots of stories. Not a lot of proof for those stories.
