Grotta di Lourdes (also Grotta della Madonna di Lourdes) is an artificial cave in the Vatican gardens. It was built in 1902–05 and is a replica of the Lourdes Grotto in France. The context of building this grotto is the vision of the Madonna that a young girl, Bernadette Soubirous, experienced 18 times. Prior to that the Pope had promulgated the dogma of the Immaculate Conception in 1854. Read more on Wikipedia
