The Mosque of Omar in Jerusalem is located opposite the southern courtyard of the Church of the Holy Sepulchre in the Muristan area of the Christian Quarter.  After the Siege of Jerusalem in 637, Patriarch Sophronius refused to surrender except to the Caliph Omar himself. Omar travelled to Jerusalem and accepted the surrender. He then visited the Church of the Holy Sepulchre where Sophronius invited him to pray inside the church, but Omar declined. Instead he prayed outside, on the steps east of the church. A wooden “Mosque of Omar” was later built at that site where Omar prayed.  The current Mosque of Omar however, was built at a different site than the one where Caliph Omar has allegedly prayed. This new position is likely due to the fact that the entrance to the Church of the Holy Sepulchre had by then moved from the east to the south of the church. Another nearby mosque, the Al-Khanqah al-Salahiyya Mosque, located on the other (northern) side of the Church of the Holy Sepulchre, has an almost identical minaret. The two minarets were obviously designed as a pair, and it is interesting to notice that a line connecting the two minarets would intersect the door of the Tomb of Jesus inside the church. Murphy-O’Connor suggests that the Mamluk rulers may have had the intention to nullify the Holy Sepulchre, since Islam does not support the notion of Jesus’ crucifixion and death.
