The Communications Museum contains a number of exhibitions that show the different stages of the development of communications technology through different historical eras and periods. Here you can explore the history of the first postal system, see many ancient telephones, learn about communication languages used in wars, and see many valuable telegraphs. When you come to the museum, be sure to look at its impressive collection of thousands of postage stamps, some of which were used during the early days of the postal service. This museum holds many temporary exhibitions so that museum-goers do not get bored of the existing exhibits, and it holds many wonderful workshops and discussions.
