is located inside the Castellani Palace in Piazza dei Giudici. The Museum contains the precious scientific instruments from the Medici and Lorraine family collections. It is one of the most important collections in the world and it also includes Galileo Galilei's original instruments.
The scientific collection was started by Cosimo I, who kept it in Palazzo Vecchio in the Sala delle Carte Geografiche (Hall of Geographical Maps); in 1600, his son Ferdinando I moved it to the Stanzino delle Matematiche (Mathematics Room) in the Uffizi Gallery . In 1775, Grand Duke Leopoldo of Lorraine founded the Royal Museum of Physics and Natural History in Palazzo Torrigiani. In 1930, the Institute of the History of Science was created, now the Museo Galileo, to which the University of Florence entrusted all the Medici-Lorraine scientific collections. In 2007, a large bronze sundial with brass and travertine inlays was installed in Piazza dei Giudici and, thanks to the glass polyhedron placed on top of the large stele, it indicates the real solar time and the date. The hours are visible on the ground, thanks to some brass radial lines, while the date is indicated by travertine transverse lines that mark the path of the sun.
