The coronation oil was created using olives harvested from two groves from monasteries on the Mount of Olives — a mountain ridge on the eastern borders of Jerusalem’s Old City.
The site has great significance to Christians: The Bible says Jesus prayed on the day before his crucifixion. The olives were picked from groves at the Monastery of Mary Magdalene and the Monastery of the Ascension and pressed into oil just outside Bethlehem, believed by Christians to be the birthplace of Jesus.
