Washington, D.C. is a city widely recognized for its monuments, memorials, and landmarks. Visitors are routinely drawn to the great sites that mark the nation's history such as the Vietnam Veterans Memorial, Arlington National Cemetery, the Lincoln Memorial, and the Washington Memorial, among others. One site that is often overlooked is the Washington National Cathedral. From its home atop Mt. St. Alban (a hill in the city's northwestern quadrant), the cathedral (also known as the Cathedral Church of Saint Peter and Saint Paul) towers in elevation above the rest of the city, even the Washington Monument. The cathedral is certainly worth a visit when visiting Washington, D.C. for its beauty and for its contribution to U.S. history. In this article, the authors describe the history of the structure and notable events that happened in the cathedral--as well as a few curious facts about this landmark. (Contains 5 notes.)
