Palazzo Madama stands in the centre of Castle Square. The history of the Palace reflects the history of the city. Infact its baroque facade contrasts sharply with older medieval parts to lend the building a most unorthodox apparence. The palace incorporate parts of ancient Roman gate, wich was converted into a castle in the Middle Ages. In the 17th century it became the residence of the Madama Reale (Royal Widow). In 1721 Filippo Juvarra enbellish the palace with a splendid baroque facade. The Palace housed the work of Subalpine and Italian Senate from 1848 to 1864. Today, it's used like Civic Ancient Art Museum (Museo Civico di Arte Antica).
