Isn't the Ark supposedly in some fleaspeck church in the Sudan or some such? I remember seeing a tv special on the Ark that traced it through its journey, and eventually tracked it to this little sub-saharan church on the Nile. Supposedly it was brough there by Jews fleeing enslavement by Babylon or some such. They couldn't prove the ark was there because the priest said no one was allowed to get too close to it (natch), but they had reasonably good supporting evidence to suggest it might really be there.
Ethiopia I thought.
