The Cathedral's initial benefactor, Thomas O'Neill is honored near the Sacristy because of his visionary understanding of the importance of building a cathedral, although the city of Baltimore and the Archdiocese of Baltimore already had a basilica that served as the home of the Premier See of the United States. Our cathedral has become a community gathering place for many important public events.
