He ascended Mt. Zion to the Coenaculum, the hall in which the Last Supper had taken place, on a new road which had been constructed in his honor.
The way to Mount Zion was a narrow dirt-track. While preparations were under way for the visit of Pope Paul VI to Jerusalem in January 1964, therefore, it was decided to widen the path and lay a proper road. The Pope had expressed a wish to pray at the Coenaculum; an improved road would make his journey more comfortable. The Jordanians did not object and the road was laid to within about 60 meters of the Coenaculum.
In 1964 Pope Paul VI visited Mount Zion. The road that winds around the right side of the mountain was built especially for the car that drove him to Dormition Abbey and to the Cenacle — site of the Last Supper.
It can be reached by car on the "Pope's Road", built in 1964 on the occasion of his visit.
