St. Peter's Basilica inside

Supposed to be the biggest church, I wasn't super impressed, but I have seen the world's tallest cathedral which IMO is equally impressive, and since I used to live by and study by that world's tallest Cathedral(in Ulm, Germany) I think I've been desensitized by big churches. Also they were preparing for mass, so much of the church was closed off to tourists, which prevented me from getting the full feel of the church or it's full depth.

I did find it horribly pretentious that they had markers on the floor to show how much smaller other churches were in comparison XD
