The Postal and Telegraphical museum of Trieste, located in the historical Palazzo delle Poste (Post Office building) in Trieste, witnesses the evolution of postal services from mid-19th century to present times. The exhibition is subdivided into various sections: the post, with relics and documents from Austrian times to modern ages; the telegraphy, with telegraphic machinery and equipment of different ages and types; the postal cartography, with historical maps of the postal routes; the military post, with the complete equipment for a camp post office. An octagonal structure hosts the reconstruction of a late 19th century post office. Lastly, worthy of mention are the collections of postal history and philatelics, which periodically alternate.
