No human society can function without the exchange of information. Named after the Russian scientist and inventor Aleksander Stepanovich Popov, the Museum aims to inform about the history of innovations and inventions in the field of technology. It is one of the oldest museums of science and technology in the world but is distinctly contemporary in outlook, documenting for example, new achievements in the fields of telecommunications. The exhibition begins with the oldest ways of delivering messages, from stage coaches to radio to the telephone. Its archives contain more than 8 million items, such as a huge collection of stamps, and old postboxes. It is highly recommended for children as it is very interactive. During working hours the following services are available: post office, research library, cafeteria, internet-cafe and souvenir shop. It is a little hard to find, but worth searching for.
