This is the emergency staircase of "Palazzo della Ragione", a building dated 1233 located in Mercanti square, Milano. Each step of this staircase is made with 116 pieces of glass.
This is my first shot with the Samyang fisheye. Ironically I preferred to trim the picture, thus reducing the extrawide view offered by this lens.
