File:Clerestory window over Kellogg Bay - North Nave By J - National Cathedral - DC.JPG

English: "Universal Peace" -- a stained glass clerestory window on the north side of the nave at the Washington National Cathedral in Washington, D.C. It is located in the Kellogg Bay, which is dedicated to Frank Billings Kellogg. He was a U.S. Senator, Secretary of State, Judge at the World Court at The Hague, and co-author of the Kellogg-Briand Pact (which attempted to outlaw war as a national policy). He won the Nobel Peace Prize for his efforts. The window was designed and fabricated by Joseph G. Reynolds, Jr. It was dedicated in 1940.

The left window features soldiers marching over the bodies of the dead (bottom) and the signers of the Kellogg-Briand Pact (above). In the right pane, people beat swords into plowshares (bottom) while the throne of God (on which Jesus, the Lamb of God, stands) allows justice to flow out like mighty waters.

A "clerestory" window is one that is high above the floor, and usually is quite narrow. They are designed to allow light into a cathedral.

Originally, the cathedral building committee required that all stained glass in the cathedral be the modestly colored English-style stained glass. Lawrence Saint designed most of the stained glass windows for the chancel, choir, and side chapels. But in the 1950s, financial patron James Sheldon convinced the building committee to abandon that plan in favor of the more vibrant, light-filled style of the French and Spanish cathedrals. This is why the Washington National Cathedral has such vibrant, glowing windows instead of gloomy pastels that let in almost no light.
