Finally liberated from the demons, that corner of Rome could be devoted to Christian worship. Paschal II, to the sound of hymns, placed the first stone of an altar at the former site of the walnut tree. This was incorporated into a simple chapel which was completed in three days. The construction was celebrated with particular solemnity: the Pope consecrated the small sanctuary in the presence of a large crowd, accompanied by ten cardinals, four archbishops, ten bishops and other prelates. He also granted the chapel many relics and dedicated it to the Virgin Mary.
