Since the 7th century, the Muslim Nuseibeh family has been responsible for opening the door as an impartial party to the church's denominations. In 1187, Saladin took the church from the Crusaders and entrusted the Joudeh Al-Goudia family with its key, which is made of iron and long; the Nuseibehs remain its doorkeepers. The 'immovable ladder' stands beneath a window on the façade. Just inside the church entrance is a stairway leading up to Calvary (Golgotha), traditionally regarded as the site of Jesus' crucifixion and the most lavishly decorated part of the church. The exit is via another stairway opposite the first, leading down to the ambulatory. Golgotha and its chapels are just south of the main altar of the Catholicon. Calvary is split into two chapels, one Greek Orthodox and one Catholic, each with its own altar. On the left (north) side, the Greek Orthodox chapel's altar is placed over the rock of Calvary (the 12th Station of the Cross), which can be touched through a hole in the floor beneath the altar. The rock can be seen under protective glass on both sides of the altar. The softer surrounding stone was removed when the church was built. The Roman Catholic (Franciscan) Chapel of the Nailing of the Cross (11th Station of the Cross) stretches to the south. Between the Catholic and the Orthodox altar, a statue of Mary with an 18th-century bust marks the 13th Station of the Cross. On the ground floor, just underneath the Golgotha chapel, is the Chapel of Adam. According to tradition, Jesus was crucified over the place where Adam's skull was buried. According to some, the blood of Christ ran down the cross and through the rocks to fill Adam's skull. Through a window at the back of the 11th-century apse, the rock of Calvary can be seen with a crack traditionally held to be caused by the earthquake that followed Jesus' death; some scholars claim it is the result of quarrying against a natural flaw in the rock. Behind the Chapel of Adam is the Museum of the Greek Orthodox Patriarchate, which holds many relics, including a 12th-century crystal mitre alleged to have once held a fragment of the Holy Cross. Just inside the entrance to the church is the Stone of Anointing (also Stone of the Anointing or Stone of Unction), which tradition believes to be where Jesus' body was prepared for burial by Joseph of Arimathea, though this tradition is only attested since the crusader era (notably by the Italian Dominican pilgrim Riccoldo da Monte di Croce in 1288), and the present stone was only added in the 1810 reconstruction.
