The United States Air Force Academy Cadet Chapel, completed in 1962, is the distinguishing feature of the Cadet Area at the United States Air Force Academy north of Colorado Springs.

The most striking aspect of the Chapel is its row of seventeen spires.The structure is a tubular steel frame of 100 identical tetrahedrons, each 75 feet  long, weighing five tons, and enclosed with clear aluminum panels.   The tetrahedrons are spaced a foot apart, creating gaps in the framework that are filled with 1-inch-thick  colored glass. The tetrahedrons comprising the spires are filled by triangular clear aluminum panels, while the tetrahedrons between the spires are filled with a mosaic of colored glass in aluminum frame.[Read More]
