"The Cathedral of St. John the Divine on 112th and Amsterdam in Upper Manhattan’s Morningside Heights is the largest cathedral in the world and the sixth-largest church by area. Hundreds of thousands of visitors walk through these doors annually for a reason. The cathedral itself—and its remarkable Gothic architecture, story-telling stained glass windows, and 17th century tapestries—is already worth visiting. But there is artwork that is especially meaningful to New York City here as well, including Keith Haring's white gold and bronze altarpiece and a 9/11 memorial sculpture by Meredith Bergmann, which holds debris of the towers in it. The cathedral holds daily and Sunday worship services, which welcome all. There is no charge to pray, meditate, or contemplate in the cathedral. Visitors who show for sightseeing purposes can enter for $5 admission. Special tours are offered depending on the day of the week." - Melissa Liebling-Goldberg, Alex Erdekian
