Climbing the cupola at St. Peters Basilica

I've received several requests for images of the narrow "cup" at the top of St. Peters Basilica in Rome. This was a 500+ step climb with winding, oddly spaced stairs, getting narrower the closer we came to the top. It was a quick climb, maybe 5 minutes, with many locals climbing in heels. Here is the steep, winding staircase where I got horrible vertigo on the way back down. I'm falliiiing!
