Museo Galileo

A museum of the history of science housed in the Palazzo Castellani on Piazza dei Giudici. It holds the Medici and Lorraine collections of scientific instruments: more than 5,000 objects, of which around 1,000 are on permanent display across 18 rooms on two floors. The most celebrated exhibits are the two surviving telescopes that Galileo built himself. The ground floor traces the Medici mathematical instruments, while the upper floor covers the Lorraine contributions to electricity, electromagnetism, and chemistry.
