Glass Steps

The glass architecture of the modern city turns even a staircase into a spectacle. Here a transparent glass stair and its cylindrical glass-walled shaft let you watch the building from inside its own structure — engineering that hides nothing, all panels, bolts, and clear treads.

Photographed May 2013, looking up. Feet and silhouettes move across the glass overhead, the spiral of panels and steel fittings curving away. Black and white turns it abstract — light, glass, and the dark shapes of people walking on air.
