Seventeenth Church of Christ, Scientist, built in 1968, is a modern style Christian Science church building located in The Loop at 55 East Wacker Drive, (at Wabash Avenue) in Chicago, Illinois in the United States. It was designed by noted Chicago-based architect Harry Weese, whose most famous work is the Washington Metro but who is remembered best as the architect who "shaped Chicago’s skyline and the way the city thought about everything from the lakefront to its treasure-trove of historical buildings."
