Fodor's Expert Review Church of the Covenant

This 1867 Gothic Revival church, a National Historic Landmark at the corner of Newbury and Berkeley Streets, has one of the largest collections of liturgical windows by Louis Comfort Tiffany in the country. It's crowned by a 236-foot-tall steeple—the tallest in Boston—that Oliver Wendell Holmes called "absolutely perfect." Inside, a 14-foot-high Tiffany lantern hangs from a breathtaking 100-foot ceiling. The church is now Presbyterian and United Church of Christ.
