The Our Lady of Lourdes Grotto in Heiligenkreuz is a Lourdes grotto in Heiligenkreuz, a municipality in the Vienna Woods in the district of Baden near Vienna, which was created in 2017 by the Heiligenkreuz Abbey as a religious monument in honor of the Blessed Virgin Mary. Like all similar grottoes of Our Lady of Lourdes around the world, it is reminiscent of the world-famous grotto of the apparition of the Virgin Mary in the French pilgrimage town of Lourdes.
