A reflective site for Marian believers, these stone caverns function as a New World counterpart to the famous French shrine to Our Lady of Lourdes, where it’s said the Virgin Mary’s apparition once appeared. You’ll marvel at the naturally formed twin grottos, positioned across the road from each other, as well as the oversize statue of the Virgin Mary, which weighs in at 1,500 pounds. A priest named Erkamp and his parishioners placed the imposing icon here in 1958.
