The Upper East Side is a luxurious neighborhood, and the Episcopal Church of the Heavenly Rest fits right in with the grand buildings nearby. Architecture fans won’t want to miss the Gothic-inspired church, known for its Art Deco design and the altar's carved reredos. Art enthusiasts should go to see the church's stained-glass windows, designed in the Arts & Crafts style.
Visit the church independently, or take advantage of a flexible hop-on hop-off bus tour—most include stops on Fifth Avenue. For a well-rounded day uptown, plan to visit the Church of the Heavenly Rest along with a nearby museum, then take a stroll in Central Park.
