One of the oldest and holiest Christian churches known to Westerners as the Church of the Holy Sepulchre. It was established by Queen Helena, the mother of King Constantine in the year 335 AD, and she built three buildings in the place, the first of which is the Church of Calvary at the place of the crucifixion according to Christian belief. Today it is located on The right of the entrance to the Church of the Holy Sepulcher, and the second one above the Holy Sepulcher, which is the place where Christians believe that Jesus was buried. And the third is above the well in which the three crosses were found, through which the church was located, but the Crusaders who occupied Jerusalem in 1099 CE united the church geometrically in the form of a cross.
