The observatory was established in Juvisy-sur-Orge in 1883 by the French astronomer and author Camille Flammarion. In March 2010, the structure was classified as a historical monument by the French Ministry of Culture. The observatory belongs to the Société astronomique de France.
The observatory is located on Route nationale 7 (formerly the avenue de la Cour de France), close to the downtown of Juvisy. The site, which is on a prominent hilltop location, is a large parcel of land that contains several buildings, a monumental gate, gardens, and a small forest.
The building housing the observatory was originally a post house constructed in 1730. In 1883–1884, Flammarion transformed the structure into an astronomical observatory by adding a large equatorial room for the telescope, a library, a scientific museum, a meteorological station and an agricultural research station. [1]
In 1899, the architect François Giamarchi was commissioned to transform the east façade of the building (garden side) by adding a decorative relief of ionic columns supporting a cornice. [2]
In 1910, Flammarion installed a vertical sundial on the upper level of the observatory. The sundial was restored in 1998 and 1972. [3]
In March 2010, the French Ministry of Culture classified the building and the large gate as protected historical monuments. [4]
Flammarion's second wife, Gabrielle Renaudot Flammarion, bequeathed the entire site to the Société Astronomique de France upon her death in 1962. In 1971, the society signed a 99-year lease with the municipality of Juvisy to ensure the site's maintenance, preservation and accessibility. Today, the society organises regular observations at the observatory for the general public. [5]
The 5 meter dome was constructed by the engineer Adolphe Gilon. It houses Camille Flammarion's equatorial mount refracting telescope, which has a diameter of 240 mm and a focal length of 3600 mm. The telescope was built by Denis Albert Bardou, a Parisian optics manufacturer. Flammarion's choice of the telescope was inspired by a similar instrument in the west tower of the Paris Observatory. [6]
Astronomers who conducted research at the observatory included:
The results of their research at the observatory were published in numerous articles and photographs in L'Astronomie, the journal of the Société astronomique de France.
In 1906, German astronomer Max Wolf discovered a minor planet orbiting the Sun and named it 605 Juvisia in honor of the location of Flammarion's observatory.

Joseph Jean Pierre Laurent was a French amateur astronomer and chemist who discovered the asteroid 51 Nemausa in 1858, for which he was a recipient of the Lalande Prize awarded by the French Academy of Sciences. It is also likely that he is the same person as the person of that name who provided chemistry assistance to photography pioneer André-Adolphe-Eugène Disdéri in 1853.
Bernard Ferdinand Lyot was a French astronomer.
Nicolas Camille Flammarion FRAS was a French astronomer and author. He was a prolific author of more than fifty titles, including popular science works about astronomy, several notable early science fiction novels, and works on psychical research and related topics. He also published the magazine L'Astronomie, starting in 1882. He maintained a private observatory at Juvisy-sur-Orge, France.

The Astronomy Tower of the Sorbonne is a tower at the Sorbonne University's Paris campus built to house an astronomical observatory for its students. The structure was erected during the reconstruction of the Sorbonne, between 1885 and 1901. The tower is 39 meters high, has an upper and lower dome, and includes several rooms. The upper dome houses the telescope, and the lower dome contains an optics workshop for amateurs to make mirrors. The tower is operated by the Société astronomique de France and is available for tours and amateur observations.
