Benedetto Maurizio di Savoia was the youngest son of Carlo Emanuele III, King of Sardinia, (1701-1773) and his third wife Elisabetta Teresa of Lorena (1711-1741). Benedetto Maurizio married his niece, Marianna di Savoia, the daughter of Vittorio Amedeo III, King of Sardinia, (1726-1796) in 1775.
The name of Benedetto di Savoia is connected to the refurbishment of the important Palazzo Chiablese. This historical Turinese building, owes its harmonious architectural style to the architect Benedetto Alfieri, who was commissioned by Carlo Emanuele III in 1753 to modify the neglected palace in order for it to become the residence of his son, Benedetto Maurizio. Upon the death of the Duke in 1808, the palace fell into a state of disrepair. It was inherited by Carlo Felice, King of Sardinia, (1765-1831) then by Ferdinando di Savoia, Duke of Genoa, (1822-1855) and most notably was the place of birth of his daughter Margherita, the first Queen of Italy. The palace was later severely damaged during the Second World War, but has since been restored.
