Английская Википедия:Camille Flammarion Observatory
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.
Building and grounds
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]
Telescope
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]

605 Juvisia
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.
