|Sistine Chapel's Secret Staircase.|
I usually don't take photos of interiors as the lighting is usually bad. In this case, it was different. With the help of technology, I managed to get some nice bokeh and blurs to enhance the shot. Shot with the iPhone 7 plus. I dig its camera.
Addendum: Rose reminded me that this was the modern double helix staircase designed by Giuseppe Momo in 1932, and was inspired by the original Bramante Staircase. This staircase, like the original, is a double helix, having two staircases allowing people to ascend without meeting people descending; as with the original the main purpose being to allow uninterrupted traffic in each direction. Kind of like driving in the Los Angeles Freeway.
