The Chapel of the Ascension (Hebrew: קפלת העלייה‎ Qapelat ha-ʿAliyya, Greek: Εκκλησάκι της Αναλήψεως, Ekklisáki tis Analípseos) is a shrine located on the Mount of Olives, in the At-Tur district of Jerusalem. Part of a larger complex consisting first of a Christian church and monastery, then an Islamic mosque, it is located on a site the faithful traditionally believed to be the earthly spot where Jesus ascended into Heaven after his resurrection. It houses a slab of stone believed to contain one of his footprints. The Status Quo, a 250-year-old understanding between religious communities, applies to the site. Shortly after the death and resurrection of Jesus, early Christians began gathering in secret to commemorate his Ascension at a small cave on the Mount of Olives. The issuance of the Edict of Milan by the Roman Emperor Constantine I in 313 made it possible for Christians to worship overtly without fear of government persecution. By the time of the pilgrim Egeria's travels to Jerusalem in 384, the spot of veneration had been moved to the present location, uphill from the cave, which had been integrated into the Constantinian Church of Eleona, dedicated by then just to Jesus' teachings about good and evil (Matthew 24:1-26:2). Egeria witnessed the celebration of the Ascension at an "open hillock" near the cave. The first church was erected there a few years later, sometime before 392, by a lady from the imperial family, Poimenia. Later a legend attributed the church to Saint Helena, mother of Constantine I. The legend holds that during Saint Helena's pilgrimage to the Holy Land between 326 and 328, she identified two spots on the Mount of Olives as being associated with Jesus' life - the place of his Ascension, and a grotto associated with his teaching of the Lord's Prayer - and that on her return to Rome she ordered the construction of two sanctuaries at these locations.
