and the municipality of Florence. The collection was housed in apartments recently vacated by members of the Italian Royal family. The gallery was first opened to public viewing in 1928. Today, further enlarged and spread over 30 rooms, this large collection includes works by artists of the Macchiaioli movement and other modern Italian schools of the late 19th and early 20th centuries. The pictures by the Macchiaioli artists are of particular note, as this school of 19th-century Tuscan painters led by Giovanni Fattori were early pioneers and the founders of the impressionist movement. The title "gallery of modern art" to some may sound incorrect, as the art in the gallery covers the period from the 18th to the early 20th century. No examples of later art are included in the collection since In Italy, "modern art" refers to the period before World War II; what has followed is generally known as "contemporary art" (arte contemporanea). In Tuscany this art can be found at the Centro per l'arte contemporanea Luigi Pecci at Prato, a city about from Florence. Treasury of the Grand Dukes The Treasury of the Grand Dukes (Tesoro dei Granduchi), formerly called the Silver Museum (Museo degli Argenti), contains a collection of priceless silver, cameos, and works in semi-precious gemstones, many of the latter from the collection of Lorenzo de' Medici, including his collection of ancient vases, many with delicate silver gilt mounts added for display purposes in the 15th century. These rooms, formerly part of the private royal apartments, are decorated with 17th-century frescoes, the most splendid being by Giovanni da San Giovanni, from 1635 to 1636. The Silver Museum also contains a fine collection of German gold and silver artefacts purchased by Grand Duke Ferdinand III after his return from exile in 1815, following the French occupation. Porcelain Museum First opened in 1973, this museum is housed in the Casino del Cavaliere in the Boboli Gardens. The porcelain is from many of the most notable European porcelain factories, with Sèvres and Meissen near Dresden being well represented. Many items in the collection were gifts to the Florentine rulers from other European sovereigns, while other works were specially commissioned by the Grand Ducal court. Of particular note are several large dinner services by the Vincennes factory, later renamed Sèvres, and a collection of small biscuit figurines.
