There's some open space around the museum as well, where you can take in bits of the rest of Vatican City. However, if you're interested in mingling with the cardinals, you'd have to get through some pretty tough security. There's a big central courtyard, which is a great place to break your visit. You can also admire the great dome of St. Peter's cathedral, the only other publicly accessible part of this golf course-sized country. Somewhat obnoxiously, the powers that be arranged that, despite the insignificant size of the country, visitors would have to walk almost a mile from the museum exit to the cathedral entrance. After five hours at the museum, we needed a lunch break along our trek to the cathedral.
