It wasn't until nearly the end of our morning at Poveglia that I explored a corner of the building that seemed to contain equipment for cleaning and sanitizing. This spiral staircase was on one side but it was getting late and I didn't get a chance to see where it went.

This was photographed with an Olypmus OMD-EM1 and an Olympus 7-14mm lens. Multiple exposures were taken and later combined in Photomatix to address the contrast differences.
