Look at this. And track forward to look at the interior as well.
I'm ashamed to confess that I lived in Oklahoma for many years, in OKC for a year, and never heard of this chapel, nor heard of its architect, Duane Conner. The photographer of this set is Conner's granddaughter, presenting a gift to future generations by documenting his work.
Note that the fantastic windows were designed by returning WW2 vets attending Central State University on the GI bill!
