Archdiocese of Baltimore
The Co-Cathedral of Mary Our Queen was consecrated by Bishop Jerome Sebastian on October 13, 1959. The construction of the Co-Cathedral was largely financed by funds donated by Mr. Thomas O’Neill of Baltimore, in whose honor the chapel of St. Thomas More was constructed. The architectural style of the sandstone and brick structure, located at the northern end of the city, near St. Mary’s Seminary and Loyola University is late art deco. The Co-Cathedral has the distinction of having been visited by Pope John Paul II, a plaque located at the entrance to the chapel of the Blessed Sacrament commemorates the Holy Father’s visit.
