Saint Mary, Star of the Sea Catholic Church
Who We Are
Adorned with Statuary and offering both traditional and contemporary Masses
St. Mary, Star of the Sea and Our Lady of Mercy Parishes in Duluth, MN are nourished and lead by one pastor, Fr. John C. Petrich. St. Mary is in the heart of Downtown Duluth and Our Lady is on Park Point.
St. Mary is adorned with magnificent statuary and stained glass windows and is of Polish descent. Many Polish families still find their way here and, being at the heart of Downtown, we are a melting pot of people of all walks of life.
Home to the only 24-hour Eucharistic Adoration Chapel in Duluth, St. Mary is unique in its calling to all Catholics of the area.
