Picture galleries in Florence include the Uffizi and the Pitti Palace. Two superb collections of sculpture are in the Bargello and the Museum of the Works of the Duomo. They are filled with the creations of Donatello, Verrochio, Desiderio da Settignano, Michelangelo and others. The Galleria dell'Accademia has Michelangelo's David – perhaps the best-known work of art anywhere, plus the unfinished statues of the slaves Michelangelo created for the tomb of Pope Julius II. Other sights include the medieval city hall, the Palazzo della Signoria (also known as the Palazzo Vecchio), the Archeological Museum, the Museum of the History of Science, the Garden of Archimedes, the Palazzo Davanzatti, the Stibbert Museum, St. Marks, the Medici Chapels, the Museum of the Works of Santa Croce, the Museum of the Cloister of Santa Maria Novella, the Zoological Museum ("La Specola"), the Bardini, and the Museo Horne. There is also a collection of works by the modern sculptor, Marino Marini, in a museum named after him. The Strozzi Palace is the site of special exhibits.
