Considered to be the largest cathedral in the world, The Cathedral of Saint John the Divine offers not only services, talks, and concerts, but also education programs. In these programs, the cathedral is used for site-specific learning, a chance to connect math and engineering principles with real-world uses and iconic New York grandeur. Here, as flying buttresses and stained glass help students learn math, they are also discovering art, engineering, and history, and how all four are related, as well as how the abstractions of traditional school subjects are necessary to the making of everything that surrounds us.
