The Museum of Physics in Naples can be found in the group of buildings erected between 1937 and 1940 to house ‘Mostra d’Oltremare’ - the triennial fascists’ fair. In this collection are scientific instruments from the 19th Century up to the 1920s and 30s. Of note is a unique collection of instruments from the Bourbons physics laboratory. The museum is open on request and there are guided tours and a photographic archive. There is no charge for admission.
