Captured wonderfully by Thomas Hawk is this elegant spiral staircase located at the Embarcadero Center in San Francisco’s financial district. Spanning four city blocks, the Embarcadero Center is a commercial complex of five office towers with over 3 million square feet of office and retail space.

The Embarcadero Center has numerous spiral staircases but this is certainly one of the most photographed and surely the most geometrically elegant spiral staircases in the complex. Even the tiles are hypnotic! A fantastic composition and great use of black and white.
