The Cathedral Church of Saint John the Divine is not merely for the faithful, but for anyone who appreciates impressive architecture. This huge structure is not only the fourth largest church in the world, but it's also one of America's crown jewels when it comes to stone work, a truly stunning example of expert design and craftsmanship. Inside, the large pipe organ, a number of stained glass windows and artist-created altars present a magnificent image. Inside the church, there is a poet's corner as well, which notes the distinguished contributions of celebrated American authors. Construction on the church began in 1882 and though it has received countless refurbishments and additions, it is still not complete according to the original design.
