Since 1892, the construction of this titanic cathedral has been stretching over more than a century, blending Roman, Byzantine and French Gothic styles in an unmatched unfinished masterpiece in the world. Imagine a rose window with 10,000 pieces of stained glass filtering magical light, granite columns weighing 130 tons each, and a vibrant altar by Keith Haring alongside works from the XV century. In the heart of Harlem, this warm episcopal site honors firefighters of September 11th in its Work Chapel, houses a Poets' Corner and verdant gardens. Self-guided tours with information in 9 languages, open doors since today until 2099. A living treasure where New York history and art cross audaciously.
