United States Air Force Academy Cadet Chapel (Colorado Springs, Colorado)
Not a Catholic church but one open to all denominations, the Air Force Academy Cadet Chapel is highly regarded for its modern architecture. The building features 17 spires that span its length. The design originally called for 21 spires, but it was reduced due to monetary restrictions. As this place of worship is owned by the US government, it contains spaces for people of all faiths to worship.
