The Grotto will be unlocked every day in May from 9 am to 7 pm for you and your family and friends to come and pray. Bring a candle and/or flowers if you wish. The Grotto is one of the lovely and prayerful spots on our Cathedral grounds. Come and discover it for yourself—an oasis of prayer in the heart of the city. St. Mary wants nothing but that we love and follow her Son and wishes to inspire and intercede for us.
