The Paris observatory is the origin point of the meridian in France, geodisic meridian (1729-Jacques Cassini) that crosses the country from Dunkerque to Perpignan (meridian used for the first map of France). It was in 1884 that an international convention adopted the meridian of Greenwich as the meridian of origin.
