World’s Oldest Museums – Musei Capitolini in Rome, Italy

Unsurprisingly, the prestige of being the oldest building containing old things is fought over quite vigorously by people who should perhaps know better.
Anyway, just about every place housing a dusty old relic will claim to be the oldest museum by inserting some kind of sub-clause, but the most convincing argument comes from the Musei Capitolini (Capitoline Museums) in Rome, Italy.
They go back to 1471, although they would have been admittedly a pretty poor effort back then, containing only some bronze statues donated by Pope Sixtus IV.
It was 1734 before the museums opened to the public, and is now home to a wealth of artefacts from the Roman Empire, as well as various impressive sculptures.
