The Cathedral of Mary Our Queen is a Catholic cathedral located in northern Baltimore, Maryland. The structure, remarkable in size, was completed in 1959. The cathedral is the seat of the Archbishop of Baltimore, joining the Basilica of the National Shrine of the Assumption of the Blessed Virgin Mary, on Cathedral Street at Mulberry Street, in downtown Baltimore. Because the archdiocese is the premier see of the United States and the downtown basilica was the nation's first Catholic cathedral, this second edifice now serves as co-cathedral. Location The cathedral is located in the Homeland area of northern Baltimore near Loyola University Maryland and St. Mary's Seminary and University, the first Catholic seminary in the United States. It was constructed using funds bequeathed by an Irish Baltimore merchant, Thomas J O'Neill. It is said to be "the only cathedral in the 2,000 year history of the Church that was donated by a single individual." History Groundbreaking In October 1954, ground was broken for the new cathedral. On the morning of October 13, 1959, a few days past the fifth anniversary of the groundbreaking, Bishop Jerome Sebastian consecrated the cathedral. Building The design is modified Gothic with Art Deco accents, constructed of brick faced with limestone, and uses a classical east-facing cruciform floor plan. The cathedral measures long, wide and to the top of the two spires and can accommodate 2,000 people. The Cathedral features and extensive sculptural program executed by Joseph Coletti.
