Today I went over to the Vatican to draw a dome for homework. The church and the Piazza San Pietro are both very beautiful and grand in scale. The whole area was pretty touristy, so much so that they even had a hamburger stand, the first I've seen. Lots of Americans in the Piazza but also people from everywhere in the world as well, mainly Asians.
The city itself is very interesting because as a free state they have their own police although its really no bigger than any other neighborhood in Rome. If you look at old maps of the city the Vatican fell on the outskirts, and today, even though the city grew around it, it still feels somewhat separate from Central Rome.
