This museum is housed in what was once the Roman residence of Thomas Le Roy, a Breton prelate who accompanied King Charles VIII to Rome in 1494. In 1522-23, Le Roy had this elegant palazzo built by Jean de Chenevières, the architect of San Luigi dei Francesi church; the building is so refined that it was long attributed to Sangallo. Today it is home to works of Ancient sculpture (Assyrian, Egyptian, Etruscan, Greek, Roman) collected by Giovanni Barracco, a rich Calabrian aristocrat, who gave his collection to the city of Rome in 1904.
