The Cenacle on Mount ZION
This site commemorates Jesus' Last Supper, and the descent of the Holy Spirit on Pentecost. The Franciscan order constructed this building in 1335 AD, and when they were expelled in 1523, it became the Nabi Daoud mosque. Note the handsome carved mihrab (prayer niche facing Mecca), and the Crusader capitals of the columns. The Arabic inscriptions honor King David.
According to tradition it is the place where the last Supper occurred, where the apostles returned after witnessing the ascension of Jesus and where Peter delivered his sermon after the Holy Spirit had descended upon the apostles on Pentecost. The room immediately above the "Tomb of David" is dedicated to the descent of the Holy Spirit on Pentecost and is called "Chapel of the Holy Spirit."
