There are libraries and there are libraries. The Vatican Library and Secret Archive (yes it is called Secret Archive) are about as impressive as you can get. There is little chance of this Library falling prey to the modish fashion of pointlessly renaming themselves as a ‘knowledge center’ , ‘Learning resource center’ or even more laughably ‘info hub’. They don’t need to rename themselves, already one of their buildings is called the Tower of Winds.

The Secret Archive is now no longer secret, it never really was. It is just the repository for the documents of the Holy See, and as such was not public. Access is now granted to scholars, who may view the treasures within, and the wonders of the physical space.
