Built Upon a Rock Fest is a free outdoor Catholic concert to be held on the grounds of the Cathedral of Our Lady of the Rosary in Duluth, MN. After the 5:00pm Mass in the Cathedral, head across the street to enjoy the stunning on-stage musical performances from nationally known Catholic artists Ike Ndolo and Luke Spehar. Free live entertainment (and free food!) with the backdrop of beautiful Lake Superior: an exhilarating and breathtaking experience, regardless of your faith background. Eucharistic Adoration will take place in the Cathedral, coinciding with the concert, and there will be opportunities for Confession.
