The Cathedral of Saints Peter and Paul, or Washington Cathedral, is the main cathedral of the Anglican Episcopal Church in the United States. The building of the cathedral is made in the Neo-Gothic style, modeled on the English Gothic of the late fourteenth century.

It is the fifth largest cathedral in the world, and the second largest in the United States, and the third tallest building in Washington, DC.

Of the more than 200 glass mosaic windows, the most famous is the “cosmic window” in honor of the landing of man on the moon, which includes a fragment of a moonstone inlaid in the center of the mosaic.

Interred near Shepard are the ashes of Helen Keller, author, lecturer, and disability activist, and her teacher and companion, Annie Sullivan. More than 200 other notable diplomats, congressmen, and members of the military are also buried at the cathedral.
