Government Service Center, Boston, MA
"I wanted to hollow out a concavity at the bottom of Beacon Hill, a spiraling space like a conch in negative relation to the convex dome of the State Capitol on top of the hill. I wanted it to wrap around a tower which turned and was not only visible in its upward thrust but penetrating visibly below the ground."
Black, Carl John. "A Vision of Human Space: Paul Rudolph: Boston State Service Center." Architectural Record 154 (July 1973): p. 106.
