Our Lady of Loreto is the Virgin's title with respect to the Holy House of Loreto, contained within the Shrine of Our Lady of Loreto, in Loreto, Italy. A number of saints have consideed it the holiest place on earth, since in the Holy House "the Word became Flesh." The House has been been shown to be constructed of materials native to Nazareth and with dimensions which suit the site of the cave venerated in Nazareth as the home of Mary at the time of the Annunciation.
On the hillside of Nazaraeth in Christ's time it was common to adjoin a structure to one of the many caves, and so a very equitable interior climate was maintained in this partially underground home. The archeology of the House, and of the cave in Nazareth over which both the ancient and modern basilicas of the Annunciation were built, support the connection between the two.
