The Vatican archives aren't secret and anyone can apply to view documents. There's a huge waiting list, though, so don't expect to just show up and be allowed to paw at 1,000 year old documents. The relics of the Saints are highly protected, but anyone can view them.
There's nothing secret. The Vatican isn't some Dan Brown fap fantasy. You don't even have to be Catholic to go there and look around. Obviously there are private areas - like the Pope's private quarters - but whoever told you that the Vatican is like some mystical place, full of magic and wonders beyond comprehension, lied to you.

They aren’t secret. The other poster literally just told you they aren’t. The relics are mostly things like, as the other user said, dead saints. Others are objects associated with certain saints, and things like splinters of the True Cross, and so on. Things you’d otherwise see in a museum I suppose.

St. Anthony's Chapel in Pittsburgh has the largest collection of relics in the United States. Not all relics are held in the vatican.
I dunno … the Pope's bathroom? What exactly are you asking for? Super secret magic hidden things like alien bodies or caged demons? PROTIP: If it's "secret", then nobody knows about it.

That reminded me of the ending to Assassin's Creed 2 where they find aliens hidden beneath the Vatican. What a shitty video game series.
Just look at the list of templar allies. Apparently Richard Nixon and George W. Bush are on the same side as Thatcher and Putin. It's worse than Metal Gear in terms of how convoluted it all is.
