The Vatican is a pretty impressive site to visit. The Vatican Museum is way beyond vast...every single Pope added his own wing and collection to it...."humble" and "modest" were not terms these guys applied to their designs. St. Peter's itself is a good example of what I'm talking about. Look at the two pictures below and notice how tiny the people at the bottom of the columns are in comparison to the buildings and statues. Inside is all marble and gold. The floor, ceiling, and walls can only be measured in terms of acres. And there are no chairs.
Above: This Swiss guards still wear the same outfits designed by Michelangelo. And yes, they are all actually Swiss. I asked.
