The Fountainhead Part 4, Chapter 20
Dominique, now Mrs. Roark, goes to the construction site of the Wynand building. She sees the words "Howard Roark, Architect" on a plaque on the fence surrounding the building. Looking for Howard, she goes up the elevator of the unfinished building, past all of the smaller buildings in the city, to the top, where she finds nothing but Howard and the sky.
