Palazzo Madama e Casaforte degli Acaja is a palace in Turin, it was the first Senate of the Italian Kingdom, and carries its traditional name from the embellishments it received under two queens (Madama) of the House of Savoy. At the beginning of the first century BC, the site of the palace was occupied by a gate in the Roman walls from which the decumanus maximus of Augusta Taurinorum (the ancient name of Turin) departed. Two of the towers, although restored, still testify to this original foundation. After the fall of the Western Roman Empire, the gate was used as a fortified fortress in the defenses of the city. In the early 14th century, this structure was turned into a castle, a century later it was rebuilt it again in a square shape, with an inner court and a patio, and four cylindrical towers at each corner. Later on the structure became a residence for guests of the house of Savoy and now Palazzo Madama houses the Turin City Museum of Ancient Art. Despite its name, it is a large collection of paintings, statues, church ornaments, porcelain, and decorative art, mostly from the late Middle Ages to the 18th century.
