The Vatican has an overwhelming amount of priceless paintings, sculptures, tapestries, etc., and I'll post pictures of those soon. However, right now I'm going to show you some photos of domes, staircases, lamps, and buildings!
Vatican spiral staircase!
Too bad I couldn't climb on the ceiling to get an overhead view.

Zoooooom...
After we saw the Sistine Chapel
(where photo-taking was not allowed, but that's OK, because check this out!) we walked down these stairs.
The doors at the top open into the Chapel.
We also came across these stairs, which are apparently reserved for the Pope.

The top layer of building, with the buttresses, is the Sistine Chapel.
