Cadet Chapel at the U.S. Air Force Academy - Colorado Springs, Colorado

The most recognizable building at the academy, the all-faith center of worship is also the most-visited, man-made tourist attraction in the state. Its aluminum, glass and steel structure — designed by Walter Netsch Jr. of Skidmore, Owings and Merrill and opened in 1962 — features more than a dozen spires soaring 150 feet into the sky, a testament to American academic architecture.
Emmanuel Episcopal Church - Pittsburgh

An unusual shape combined with distinctive brickwork — selected as an economical choice but eventually becoming its signature — mark this 1886 building that was one of the last designs of Henry Hobson Richardson. A National Historic Landmark, the Emmanuel Episcopal Church continues to operate today as an active parish.
