Do I have to be Catholic to visit the Vatican City?

With 109 acres (44 hectares) within its walls, the Vatican is easily traveled by foot; however, most of this area is inaccessible to tourists.

No reference about Anglicans, Muslims or any other - just tourists. Any where that a Catholic can get in, you can too, regardless of your background. And also importantly, regardless of your gender - a recent change!

However:

• Since Vatican City is a Papal state, as such respect and reverence to the Roman Catholic Church and its practices and doctrine is encouraged.

• Sleeveless shirts and short pants or skirts are not permitted within the border of the Vatican.

Some areas typically off-limits can be applied for access to them, including the famous Vatican Secret Archives.

From Wikipedia:

Qualified scholars from institutions of higher education pursuing scientific researches, with an adequate knowledge of archival research, could apply for an entry card. Scholars need an introductory letter by either a recognized institute of research or by a suitably qualified person in the field of historical research. Applicants need to specify their personal data (name, address etc.) as well as the purpose of their research. Undergraduate students are not admitted.

No, there are tours for everyone. Unless a cardinal or a church employee, I can't see how one being a catholic provides any benefits there.

Getting into Vatican is pretty straightforward. There are no border checks. Problems may arise when you want to enter St. Peters Basilica. However, religious beliefs don't matter. I am not a Catholic and I have already visited Vatican and St. Peter's basilica twice. Nobody asked me about my beliefs.

I can think about three things which are eliminatory:

• Indecent dress
• Abusive behavior
• Carrying guns

Also note that for visiting places other than St. Peter's square, St. Peter's Basilica, and the museums, you need special arrangements.
