The Treasury of the Grand Dukes (formerly known as the Silver Museum) is located on the ground and mezzanine floors of Pitti Palace, occupying the rooms that were once the summer apartments of the Medici family. Its walls, entirely frescoed on the occasion of the marriage between the Grand Duke of Tuscany Ferdinando II de’ Medici and Vittoria della Rovere (1637), are one of the first examples of quadrature and trompe-l’oeil perspective in Florence. It houses the precious “Medici’s Treasure”: semi-precious stone vases, rock crystals, ambers and ivories. The silverware comes from the “Treasure of Salzburg”, from the collections of the Bishops of Salzburg brought to Florence by Grand Duke of Tuscany Ferdinand III. The Museum also houses an important collection of jewellery made between the 17th and 20th centuries and has a large section dedicated to contemporary jewellery.
