Traditionally Ethiopian emperors were crowned at the Church of Our Lady Mary of Zion in Axum, the site of the chapel in which is kept what is believed to be the Ark of the Covenant, in order to validate the new emperor's legitimacy by reinforcing his claim to descent from Menelik I, the son of King Solomon and the Queen of Sheba, who is believed to have brought the Ark from Jerusalem to Axum. Their imperial crowns were afterwards frequently donated to the church and are kept in the church's treasury, although other monarchs have given their crowns and other regalia to various other churches. The Crown Jewels used at the coronation of Emperor Haile Selassie are kept at the museum in the National Palace (formerly the Jubilee Palace) in Addis Ababa.
