An artificial cave in the Vatican gardens. It was built in 1905 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.
The Grotta di Lourdes in the Vatican is smaller than the French original but is on an appropriate scale. Is a simple structure with an evocative altar and a small statue of the Immaculate. Below this statue there is an inscription of Mary’s message to young Bernadette Soubirous.
