Loreto is one of the most important sacred places for Catholic pilgrims in the Marches Region. Its history begins December 10, 1924, when the Sanctuary of the Holy House of the Virgin Mary was moved from Nazareth to its current site; this belief is supported by the research that recently has been carried out on the graffiti found inside this house. The sacred house (Santa Casa) has a very simple structure with three walls, each of them reaching the height of three metres, composed of sandstones and refined with a particular technique that was used in Palestine in the time of Jesus. This site is remarkable for its religious and spiritual values as well as for the artistic importance of its highly-decorated marble work. Pope Julius II commissioned Donato Bramante for the marble vestments.
