The Polytechnic Museum is one of the oldest science museums in the world and is located in Moscow. It showcases Russian and Soviet technology and science, as well as modern inventions. It was founded in 1872 after the first All-Russian Technical Exhibition on the bicentennial anniversary of the birth of Peter the Great at the initiative of the Society of Devotees of Natural Science, Anthropology, and Ethnography. The first stage of the museum was designed by Ippolit Monighetti and completed in 1877. The north wing was added in 1896 and the south wing in 1907.
