Pictured here is the Lourdes Grotto located between the Chapel and the Courtyard.
The tribute refers to the Marian apparition that is reported to have appeared before various individuals on separate occasions around Lourdes, France in a grotto in the late 1850's.
The Sacred Heart grotto offers an outdoor setting for prayer and contemplation. Though I would think that only the truly brave would do so in this winter snow.
I have taken several pictures on numerous visits of this wonderful monument and feel that I have yet to capture it properly. I hope someday to feature it in its own post when I do.
