On Fifth Avenue, surrounded by glass, flagship boutiques, office towers and the constant movement of Midtown Manhattan, St. Patrick’s Cathedral looks almost impossible. Its white marble walls and Gothic Revival spires seem to have been carried here from another age, yet that is exactly its power. It does not disappear among the skyscrapers. On the contrary, it makes the city around it feel even more dramatic. In New York, where everything reaches upward, this cathedral reminds us that height can be not only architectural, but spiritual.
