Sunday museum access follows a specific calendar with exceptions. Verify your date on the official site rather than relying on a general rule about the last Sunday of the month. Special opening conditions can differ from ordinary timed admission.

A museum closure does not mean the whole Vatican area is inaccessible. The Square and Basilica follow their own security and religious-event arrangements. Check the day’s notices, especially if you hope to combine sightseeing with a public event.
