About five million people visit the Cité each year. Attractions include a planetarium, a submarine (the Argonaute), an IMAX theatre (La Géode) and special areas for children and teenagers. The CSI is classified as a public establishment of an industrial and commercial character, an establishment specialising in the fostering of scientific and technical culture. Created on the initiative of President Giscard d'Estaing, the goal of the Cité is to spread scientific and technical knowledge among the public, particularly for youth, and to promote public interest in science, research and industry.
