Tour Les Poissons

Tour Les Poissons, known in corporate real estate as Tour Ciel, is a 42-storey, 129.5 m (425 ft) skyscraper located west of Paris in Courbevoie, Hauts-de-Seine, France. While often grouped with the many office towers of La Défense business district, it is actually located half a mile to the northeast in a smaller mixed use complex called Centre Charras, of which it remains the highest building. Completed in 1970, it has occasionally been described as France's first true skyscraper, although Tour Perret in Amiens is more frequently cited. Between its inauguration and that of Tour Montparnasse in 1973, Tour Les Poissons was France's highest building designed for occupancy (which excludes antennas or observation towers such as the Eiffel Tower).
