From Wired.com comes a wonderful slide show of majestic churches. You can see it here.
These photos are the work of Christoph Morlinghaus and all are from the United States except one from Germany.
I have been blessed over the years to see magnificent church structures here in America and in Europe. Of those photographed by Morlinghaus, I have seen the Air Force Academy Chapel and Kramer Chapel at Concordia Theological Seminary, Fort Wayne IN. I was a student at Fort Wayne for two years when the campus was Concordia Senior College in the 70s.
As you travel, try to take in a good church. It will lift your spirits!
