National Cathedral Washington Dc<br />
Washington National Cathedral, whose official name is the Cathedral Church of Saint Peter and Saint Paul, is a cathedral of the Episcopal Church located in Washington, D.C., the capital of the United States. It is of neogothic design, and it is the sixth largest cathedral in the world, the second largest in the United States, and the fourth tallest structure in Washington, D.C. Its final design shows a mix of influences from the various Gothic architectural styles of the Middle Ages, identifiable in its pointed arches, flying buttresses, a variety of ceiling vaulting, stained-glass windows and carved decorations in stone, and by its three similar towers, two on the west front and one surmounting the crossing. The cathedral is located at Massachusetts and Wisconsin Avenues in the northwest quadrant of Washington. It is listed on the National Register of Historic Places. In 2007, it was ranked third on the List of America's Favorite Architecture by the American Institute of Architects.
