The Grotto, built through the generosity of donors and the dedication of Hartley families, faculty and staff, now stands as a spiritual centerpiece for the school. Nestled in the center courtyard of campus, the Grotto provides a peaceful space for prayer, reflection and devotion. At its heart is a statue of the Blessed Virgin Mary, reminding all who visit of her loving intercession and her guiding presence in the life of the Church. The particular depiction is the Immaculate Conception based off of the painting by the Spanish artist Murillo.
