a chapel
I'd seen the chapel at the United States Air Force Academy from the road; I wanted to see it up close too.
This afternoon we headed to the entrance to the base that was open to the public, driving to the location of the chapel, then walking across the open areas. It's an impressive and fascinating structure. According to the Cadet Chapel page on the U.S. Air Force Academy web page the construction was started in 1959 and completed in 1963 at a cost of $3.5 million dollars.
