Astronomical Observatory located on Avenue de l'Observatoire, in the 14th arrondissement of Paris, the Paris observatory has two other sites in Meudon and Nançay. Created in the second half of the 17th century, in 1667, it played an important role in the development of Western astronomy.
Run for 125 years by the family of Cassini, the building is somewhat battered by the French Revolution. It is gradually recovering its superb, and it is here that François Arago will develop polarimetry and photometry, producing the first daguerreotype of the Sun.
Today it is the largest French research center in astronomy, with more than 600 permanent positions. Several fields are covered like the formation of stars, astroparticles, cosmology, metrology or the interstellar system. The observatory of Paris also offers courses ranging from master to doctorate.
In order to transmit its discoveries to the general public, the site offers many events such as itinerant temporary exhibitions, visits to the observatory, open days or night observations once a year.
