I just googled where they are going, it is Ethiopia, OH MY that is different. Now I see that Axum has a church that houses the Ark of the Covenant that holds the 10 commandments. Now that is a historical and exciting thing to visit. Just Wow.
The Ethiopian Orthodox Church claims that the Church of Our Lady Mary of Zion in Aksum houses the Biblical Ark of the Covenant in which lie the Tablets of Law upon which the Ten Commandments are inscribed.[4] The historical records and Ethiopian traditions suggest that it was from Aksum that Makeda, the Queen of Sheba, journeyed to visit King Solomon in Jerusalem. She had a son called "Menelik I" from King Solomon. He grew up in Ethiopia but traveled to Jerusalem as a young man to visit his father homeland. He lived several years in Jerusalem before returning to his country with the Ark of the Covenant. According to the Ethiopian Church and Ethiopian tradition, the Ark still exist in the town of Axum
Correction, there is a chapel that houses the Ark of the Covenant and no one may go in there but the guardian monk, so you can't view it. The chapel is between the two churches.
