The Vatican Library
Though officially inaugurated in the 15th century, The Vatican Library vastly pre-dates this. Certain sources even suggest the library has existed since the 4th century. The Vatican Library houses not only the theological documents of the papacy, but other fascinating artifacts such as Henry VIII’s love letters, ancient Chinese manuscripts, and one of only 50 bibles made especially for the first ever Christian Roman Emperor, Constantine. With almost 2 million books inside its stores, the wonders of The Vatican Library know no bounds.
