One of the most valuable historical collections of scientific instruments of the Sienese university is that preserved in the Physics Section: around 400 devices, instruments and models, in perfect condition, mostly from the 19th century, which testify to the history of the discipline, from its being a subject of teaching in the study program from the origins of the Medical Faculty to the more recent Faculty of Mathematical, Physical and Natural Sciences.
The Collection of Physics Instruments is part of the SIMUS - Siena University Museum System.
