30 years ago today, construction on the National Cathedral in Washington, DC was finally completed—83 years-to-the-day after the foundation stone was laid in the presence of President Theodore Roosevelt in 1907. Including 112 gargoyles, many carved by master stone carver Roger Morigi, this Episcopal Church features a dizzying array of whimsy, including—one of its most popular attractions—a stone carving of Darth Vader installed as a gargoyle in 1986 on the building’s north “dark” side. The sixth largest cathedral in the world and the second largest in America, it is filled with memorials to persons or events of national significance, including statues of Eleanor Roosevelt, Rosa Parks, Presidents Washington and Lincoln, and stained glass commemorating events like the Lewis and Clark expedition and the raising of the American flag at Iwo Jima. Tours of the grounds host a quarter million visitors every year. There are many other works of art including over 215 stained glass windows, the most familiar of which may be The Space Window, honoring mankind's landing on the Moon, which actually has a fragment of lunar rock embedded at its center. Sitting on 57 acres atop a hill with a tower that constitutes the highest point in the nation’s capital, more than 220 people are interred in the Cathedral, including President Woodrow Wilson and Helen Keller, who is buried alongside her teacher Annie Sullivan in the Cathedral crypt.a quick video tour...
