In 1969, the Al-Aqsa mosque in Jerusalem was attacked and a precious work of art, the minbar (pulpit) of Saladin, originally installed in 1187, was destroyed. Here’s an excerpt from “Stairway to Heaven,” a film the made by The Prince’s Charities, which tells how the minbar was reconstructed with the help of Britain’s Prince of Wales and Jordan’s Prince Ghazi. Narrated by Kenneth Branagh.
