Completed in 1930, the Shrine at Lourdes exists in reinforced concrete form at Inchicore in Dublin. Measuring 50 feet in height, 130 feet in width and with a depth of 40 feet, the Grotto provides an opportunity for those unable to travel to France to express their devotion to Our Lady Immaculate. Located behind the Church of Mary Immaculate, this architectural oddity, its dimensions which match the original in South West France, remains relatively unknown here in Ireland.
