Washington National Cathedral (among the largest cathedrals in the U.S. and world, rankings vary)

The Washington National Cathedral is one of the largest cathedrals in the United States by overall size and is frequently ranked among the world's largest cathedrals; exact placement varies depending on whether measurements use interior volume, length, or other criteria. Built in a Gothic style over much of the 20th century, the Cathedral hosts national services and large public events and is noted for its expansive nave, transepts, and chapels. Because different lists use different metrics, statements about its exact rank are sometimes debated.
