Some scholars believe that when Jerusalem came under Christian rule in the 4th century, there was a purposeful transference of respect for the Temple Mount and the Western Wall in terms of sanctity to the Church of the Holy Sepulchre, while the sites around the Temple Mount became a refuse dump for Christians. However, the actions of many modern Christian leaders, including Pope John Paul II and Pope Benedict XVI, who visited the Wall and left prayer messages in its crevices, have symbolized for many Christians a restoration of respect and even veneration for this ancient religious site.
