If you walk in Paris today, maybe you saw one of these stones. They have a long and rich history.
The meridian of Paris, which is also called ” Meridian of France ” goes through the center of Paris. This invisible line was created in 1667 by a group of french scientists and was used to define the european time zone, but the project was aborted. In 1807, a man called François Arago decides to carry on with the project. Because of the war between France and Spain, he was jailed and could not never continue his work. Finally, in 1911 the meridian is officialy adopted.
Since 1994, the meridian has been physically represented with a series of 135 pavements stones of twelve centimer each. These stones were called ” Médaillons François Arago ” in tribute to this man.
They are present from the north to the south of Paris. Some of the stones have vanished, but you can find several at L’Observatoire de Paris or at Le Parc Montsouris. You can walk around Paris to follow the line…
