The Polytechnic Museum (Russian: Политехнический музей) is one of the oldest science museums in the world, located in Moscow that emphasizes the progress of Russian and Soviet technology and science, as well as modern inventions and developments. 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 Natural Science, Anthropology and Ethnography. The first stage of the museum was designed by Ippolit Monighetti and completed in 1877. Almost from the beginning, the collection was too big for the space. The north wing was added in 1896 and the south wing in 1907. At present the main building of the museum (Novaya sq., 3/4) is closed for reconstruction.
