History: The modern Church of the Pater Noster is built right next to the site of a fourth-century basilica commissioned by Constantine I to commemorate the Ascension of Jesus Christ. It was built under the direction of Constantine's mother Helena in the early 4th century, who named it the Church of the Disciples.
Importance: In the early fourth century, St. Helen visited the Holy Land, and, with the help of the local community, identified this cave as an important place where Jesus gathered his followers. She led the building of a large church here; its sanctuary covered this cave.
Location: church located on the Mount of Olives in Jerusalem. It is part of a Carmelite monastery.
