This post-World War II modern Gothic Roman Catholic cathedral is both contemporary and indicative of local architectural conservatism. Designed by prolific Roman Catholic church architects Maginnis, Walsh and Kennedy of Boston, it has a Latin cross plan with a central entrance flanked by towers. While the form and plan are traditional, down to the load-bearing masonry construction, side aisles, and buttresses, the angular lines, stylized sculptural program, and smooth random ashlar limestone walls firmly place its design in the mid-twentieth century. The massive sanctuary seats 1,900 worshippers and serves as the co-cathedral with the downtown Basilica of the Assumption for the Archdiocese of Baltimore, the first in the United States.
