PHILADELPHIA (CNS) — In front of Philadelphia’s Cathedral Basilica of SS. Peter and Paul stands a visible representation of Pope Francis’ favorite religious image: “Mary, Undoer of Knots.”
The “Knotted Grotto” is a dome-shaped lattice-work frame that stands about 10 feet high with an approximately 20-foot circumference and features tens of thousands of white ribbons knotted into a lattice structure.
Each ribbon represents a prayer intention, which visitors may read and offer in their prayers, as well as add a new ribbon.
