The Sanctuary of Our Lady of Knock in County Mayo, Ireland, marks the place where on Aug. 21, 1879, a group of villagers saw a vision of the Blessed Virgin Mary bathed in a bright light. A barefoot St. Joseph was on her right while St. John the Evangelist, vested as a bishop and wearing a mitre, was on her left. A lamb symbolizing Jesus, the Lamb of God, stood on an altar with a cross behind Him, surrounded by angels. The Marian apparition continued for two hours, and although the night was stormy, no rain fell on that spot. You can learn more and take a virtual tour while you gather as a family to make Irish potato salad. This lighter take on the country’s hearty fare pairs perfectly with summer cookouts.
