Whether you are Roman Catholic or not, a visit to the
Vatican is strongly recommended for all visitors to Rome Italy.
Separate queues exist for St. Peter's Cathedral, the
Cathedral Dome and the Vatican Museum (which includes the Sistine Chapel).
Consequently,
it is a good ideal to prioritize what to you want to see before you
arrive. There are no entry charges to visit St. Peter's, but admission charges
are applied at the museum and to climb the dome. Wait-times at each of the
attractions can be lengthy.
