Marian Grotto in Orchard Lake Village

We never cease to be amazed at the variety and beauty of what can be found in Michigan. Overlooking beautiful Orchard Lake is a unique structure called the Marian Grotto of Our Lady of Lourdes which is visited by an estimated 25,000 people a year. It is on the campus of St Mary's Preparatory School and the Orchard Lake Campus of Madonna University. In 1941 Josephine Rzeppa, a Detroit business woman, donated $5000 which was used to build the shrine in just 31 days using tufa rock from Blue Hole, Ohio.
