The shrine marking the place where Jesus is believed to have ascended to heaven offers Christians a disappointing experience. All that remains of the several churches built to celebrate the Ascension is a small octagonal structure on a property that is now part of a mosque. Plain and unadorned, the Dome of the Ascension stands in a walled compound east of the main road that runs on the top of the Mount of Olives in Jerusalem. The location is just north of the Church of Pater Noster — which is built over a cave that the first Christians used as a more secluded place to commemorate the Ascension. Map.
