This spiral staircase is located at the end of the Vatican Museum. It consists of two intertwined spirals, one leading down and the other going upwards. Taken with a Tokina 11-16 2.8 wide-angle lens. Three-exposure HDR composite, using relatively slow shutter speeds to evoke movement. Oddly, this photo is meant to be a portrait -yes, a portrait of my then 1 and a half year-old daughter and her mother, who are patiently standing still towards the middle of the frame.
