The Sanctuary of Caravaggio is a monumental religious building located in the territory of the town of Caravaggio in Lombardy, and dedicated to Our Lady of the Fountain. The erection of the Marian shrine, strongly backed by Archbishop Carlo Borromeo, began in 1575 to a design of architect Pellegrino Tibaldi (known as The Pilgrim), at the exact place of the apparition. The monumental temple stands in the middle of a vast plain surrounded by arcades symmetrical on all four sides, which run with 200 arches, for almost 800 meters. In front of the driveway connecting with the city center is an obelisk which. Just beyond the obelisk is a large fountain, whose water passes under the shrine, the sacred spring flows into the rear yard, where it is collected in a pool.
